Résumé :
Cyclohexane, methylcyclohexane, and adamantane are hydroxylated by a radical process using perbenzoic acid. A regioselectivity of 60–90% in favour of tertiary alcohols is noted. In the case of cis and trans decalins, stereoselection leading to 9-decalols can reach 97%. Such a stereoselectivity for hydroxylation by use of a peracid does not necessarily indicate lack of a radical pathway.

The new data about oxidation of unsaturated aldehydes of a general structure R–CH = C(R)–CHO by molecular oxygen (in liquid and gaseous phase), peracids and hydrogen peroxide were obtained. The composition of reaction products for a series of aldehydes with different structures was determined. The dependencies of the selectivity of reaction from an aldehyde structure and oxidant type have been evaluated. It has been assumed that a stage of aldehyde interaction with peracid determines the formation of reaction products. The common mechanisms of unsaturated aldehydes oxidation by different oxidants have been established on the basis of generalization of obtained results.

Résumé :
Herein, we report density functional calculations on the epoxidation of cyclohexene with H2O2 activated by (Me2EBC)MnCl2 (Me2EBC stands for 4,11-dimethyl-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane). The computed energy landscapes for different interaction modes of cyclohexene with the MnIV-hydroperoxo complex and the MnV-oxo species support recent experimental findings by Busch and co-workers [J. Am. Chem. Soc. 127, 17170 (2005)], according to which the MnIV-hydroperoxo species is the active complex for olefin epoxidation. Thus, the dominant olefin epoxidation pathway is via direct transfer of the distal protonated oxygen of the hydroperoxo adduct without changes in the oxydation state of its tetravalent metal centre, i.e., the mechanism commonly observed in the uncatalyzed epoxidation by peracids. The homolytic decomposition of the O–OH bond in the active manganese complex leading to the MnV-oxo species is found to be the only epoxidation pathway that could possibly compete with the Oβ transfer from the hydroperoxo adduct. However, the generated MnV-oxo is shown to be a rather poor oxidant resulting in low yields of the target epoxy cyclohexane.Key words: epoxidation, density functional theory, permanganic acid, peracid.

Résumé :
Background/Aims: Protein tyrosine phosphatases are crucial enzymes controlling numerous physiological and pathophysiological events and can be regulated by oxidation of the catalytic domain cysteine residue. Peracids are highly oxidizing compounds, and thus may induce inactivation of PTPs. The aim of the present study was to evaluate the inhibitory effect of peracids with different length of hydrocarbon chain on the activity of selected PTPs. Methods: The enzymatic activity of human CD45, PTP1B, LAR, bacterial YopH was assayed under the cell-free conditions, and activity of cellular CD45 in human Jurkat cell lysates. The molecular docking and molecular dynamics were performed to evaluate the peracids binding to the CD45 active site. Results: Here we demonstrate that peracids reduce enzymatic activity of recombinant CD45, PTP1B, LAR, YopH and cellular CD45. Our studies indicate that peracids are more potent inhibitors of CD45 than hydrogen peroxide (with an IC50 value equal to 25 nM for peroctanoic acid and 8 µM for hydrogen peroxide). The experimental data show that the inactivation caused by peracids is dependent on hydrocarbon chain length of peracids with maximum inhibitory effect of medium-chain peracids (C8-C12 acyl chain), which correlates with calculated binding affinities to the CD45 active site. Conclusion: Peracids are potent inhibitors of PTPs with the strongest inhibitory effect observed for medium-chain peracids.

Journal of Porphyrins and Phthalocyanines 17, no 01n02 (janvier 2013) : 63–72. http://dx.doi.org/10.1142/s1088424612501234.

Texte intégral
Résumé :
The mechanism of the reaction between ferric Caldariomyces fumago chloroperoxidase (CCPO) and meta-chloroperoxybenzoic acid (mCPBA) has been examined. It has previously been established that an Fe(IV) -oxo porphyrin radical species known as Compound I (Cpd I) is formed by two-electron oxidation of the native ferric enzyme by a variety of oxidants including organic peracids and hydroperoxides. Cpd I can return to the ferric state either by direct oxygen insertion into an organic substrate (e.g. a P450 oxygenase-like reaction), or by two consecutive one-electron additions, the first resulting in an intermediate Fe(IV) -oxo species known as Compound II (Cpd II). There has been much debate over the role of Cpd II and the details of its structure. In the present study, both CCPO Fe(IV) -oxo intermediates are formed, but unlike most CCPO reactions, Cpd I and Cpd II are formed using the same reactant, mCPBA. Thus, the peracid is used as an oxo donor to produce Cpd I and then as a reductant to reduce Cpd I to Cpd II, and finally, Cpd II to the ferric state. The observation of saturation kinetics with respect to mCPBA concentration for each step is consistent with the formation of CCPO-mCPBA complexes in each phase of the reaction. The original reaction mechanism for ferric CCPO with mCPBA was hypothesized to involve a scrambling mechanism with a unique Fe -OOO-C(O)R intermediate formed with no observed Cpd II intermediate. The data reported herein clearly demonstrate the formation of Cpd II in returning the oxidized enzyme back to its native ferric state.

Texte intégral
Résumé :
During Baeyer–Villiger (BV) oxidation of cyclohexanone with peracids, oligo(ε-caprolactone) (OCL) may be formed. In this work, a two-step one-pot method for the synthesis of OCL involving the BV oxidation of cyclohexanone with peracids and then oligomerization of the resulting ε-caprolactone has been developed. The process was carried out in two solvents: toluene and cyclohexane. Based on the studies, it was determined that the increased temperature (45–55 °C) and the longer reaction time (4 h) favor the formation of OCls. Among the tested peracids (perC8-C12), perC10 turned out to be the most effective oxidant. Moreover, the obtained oligomers were characterized by means of NMR, MS MALDI TOF, and TGA analyses, which made it possible to determine the structure of oligomers (length and terminal groups of the chains). Additionally, the oligomers obtained after the distillation of the reaction mixture were analyzed.

Résumé :
In current investigation, the Ni-P-W/ZrO2 electroless nanocomposite coatings are deposited upon mild steel substrate (AISI 1040 grade). The W/ZrO2 nanoparticles (50 to 130 nm range) were incorporated separately into acidic electroless Ni-P matrix as a second phase materials. The as-plated EL Ni-P-W/ZrO2 depositions were also heated at 400 οC in Argon atmosphere for one hour duration and analyzed by SEM/EDAX and XRD physical methods. The Ni-P-W/ZrO2 as-plated coupons revealed nebulous type structures while heated coupons showed crystalline structures in both cases. Furthermore Ni-P-ZrO2 coatings have very less cracks and gaps as compared to Ni-P-W coatings. The corrosion tests result in peracid (0.30 ± 0.02 % active oxygen) solutions point up that corrosivity of peracid ( 500 ppm Cl) is more than peracid (0 ppm Cl) and corrosion resistance of tested coupons varies as Ni-P-ZrO2 (as-plated) > Ni-P-ZrO2 (heated) > Ni-P-W (as-plated) > Ni-P-W (heated) > MS. The utilization of Ni-P-ZrO2 nanocomposite coatings in peracid solutions can be considered a cost effective option on the basis of its better cost/strength ratio in addition to its fair corrosion resistance.

Dans le cas du mmpp, qui en milieu aqueux se degrade plus vite qu'il ne reagit avec l'ester, on montre que les accelerations exceptionnelles observees en milieu micellaire (km/kw = 350 000m) resultent a la fois de fortes concentrations du nucleophile a l'interface micellaire et d'une reactivite km particulierement grande (km = 35 1/s). Ce resultat spectaculaire decoule en partie du choix de la glycine, plutot que du carbonate ou du borate, pour tamponner le milieu.

Résumé :
In recent years, polymer-assisted solution-phase synthesis has become a prevalent method because of its various advantages over conventional solution-phase chemistry, such as the ease of separation of the supported species from a reaction mixture by filtration and washing, the opportunity to use an excess of the reagent to force the reaction to completion, and the adaptability to continuous-flow processes. Peroxycarboxylic acids are common oxidants in a wide range of chemical transformations, but their use is often limited because of the associated handling risks. Some relatively stable peracids, such as meta-chloroperoxybenzoic acid, are commercially available, but quenching of unreacted species followed by extractions and/or chromatography separation is often required. The immobilisation of this type of reagent on a solid support can offer distinct advantages with respect to handling and stability. Carboxylic ion-exchange resins, such as acrylic macroporous matrix, can be oxidised to give highly functionalised supported peroxycarboxylic acids. The polymer-supported peracid generated from Dowex MAC-3® proved to be the best in terms of oxidation capacity among the supports and reaction conditions tested. The new high-loading polymer-supported peracid was stable under standard laboratory practice, also when it was crushed or heated, and it was used successfully in the oxidation of sulfides, alkenes, and pyridines, giving the products with high yields and purities without the need for any additional purification step.

Résumé :
L'etude realisee entre dans le cadre de la recherche de nouveaux reactifs non chlores pour le blanchiment papetier. Deux peroxyacides ont ete evalues : l'acide peroxyacetique et l'acide peroxymonosulfurique. La premiere partie a ete consacree a l'optimisation des procedes de blanchiment. Differents aspects de l'usage de ces reactifs en application au blanchiment des pates a papier chimiques kraft ont ete envisages. Ces travaux montrent que les peroxyacides sont des agents de blanchiment efficaces pouvant etre utilises pour la delignification de pates cellulosiques a fortes teneurs en lignine, comme pour parfaire la decoloration de pates comportant de faibles taux de lignine residuelle. Une application industielle a pu voir le jour decoulant de ces travaux. La seconde partie, a developpe l'etude de la caracterisation de lignines residuelles issues de pates traitees par les peroxyacides. Ce travail constitue en fait une reponse a des travaux anterieurs a cette these, sur l'effet activateur des peroxyacides. Les resultats obtenus par mesure en rmn#1#3c montrent que, contrairement au modele propose pour interpreter cet effet, les lignines issues des pates traitees ne presentent pas un enrichissement en unites phenoliques. En revanche, une reduction sensible de la teneur en unites aromatiques totales, assortie d'une conservation du ratio groupements phenoliques / groupements aromatiques totaux a ete note. Par ailleurs, les lignines residuelles se sont enrichies en groupements carboxyliques. Enfin, la troisieme partie, a etudie l'action de certains cations metalliques sur les peroxyacides. Ainsi, les peroxyacides sont decomposes catalytiquement par les metaux les plus couramment rencontres dans les pates, tels le fer ou le cuivre. De plus, les mecanismes de decomposition peuvent conduire a la generation de radicaux hydroxyles nefastes pour la qualite de la cellulose. D'autre part, l'etude de l'influence du cobalt s'est averee interessante, dans la mesure ou ce metal decompose efficacement les peroxyacides en conduisant a la generation d'especes sans consequence pour la cellulose, mais tres actives pour oxyder des molecules modeles de lignine. Ce point ouvre un champ d'applications potentiel des peroxyacides en blanchiment, en presence d'activateurs tels le cobalt ou encore les complexes de celui-ci.

Résumé :
Les mecanismes de decomposition thermique des peracides ont ete largement etudies; l'etape d'amorcage de ces processus est la rupture homolytique de la liaison o-o du peracide. La nature des produits formes depend de la structure de peracide (aliphatique ou aromatique), de la nature du solvant (donneur d'hydrogene ou non) et de la temperature. Il a ete montre que le radical acylperoxyle est vraisemblablement implique dans ces processus. Dans le but d'identifier ce radical, nous avons montre que l'utilisation du peroxydicarbonate de di(4-tert-butyl) cyclohexyle (bchpc) comme source de radicaux (alcoxycarbonyl) oxydes, tres electrophiles, permet d'induire la decomposition d'un peracide (acides peroxybenzoique et peroxydecanoique) par arrachement de l'hydrogene peroxydique et cela a une temperature suffisamment basse pour que la decomposition auto-induite du peracide soit particulierement lente. La presence du radical acylperoxyle comme intermediaire du processus de decomposition induite a ete etablie sans ambiguites par piegeage du radical sur le cis-stilbene et identification de l'epoxyde trans resultant de la reaction d'epoxydation radicalaire du cis-stilbene par le radical acylperoxyle

Résumé :
Abstract This thesis examines three different areas of water treatment technology: the application of organic peracids in wastewater treatment; the removal of organic residues from boiler make-up water; and the use of geopolymers as sorbents. The main advantages of peracids as alternative wastewater disinfectants are their effective antimicrobial properties and high oxidation power, as well the absence of harmful disinfection by-products after their use. Performic, peracetic and perpropionic acids were compared in laboratory-scale disinfection, oxidation and corrosion experiments. From the techno-economical point of view, performic acid proved to be the most effective disinfectant against E. coli and fecal enterococci. However, in the bisphenol-A oxidation experiments, no advantages compared to hydrogen peroxide use were observed. It was also determined that corrosion rates on stainless steel 316L were negligible, while carbon steel seemed unsuitable in terms of corrosion for use with peracids even in low concentrations. Organic compounds in the boiler plant water-steam cycle thermally decompose and form potentially corrosive species. Activated carbon filtration was confirmed to be a suitable method for the removal of organic residue from deionized boiler make-up water. No significant differences in terms of treatment efficiency between commercial activated carbons were observed. However, acid washing as a pre-treatment reduced the leaching of impurities from new carbon beds. Nevertheless, a mixed-bed ion exchanger was required to remove leached impurities, such as silica and sodium. Geopolymers, or amorphous analogues of zeolites, can be used as sorbents in the treatment of wastewater. Metakaolin and blast-furnace-slag geopolymers showed positive potential in the treatment of landfill leachate (NH4+ ) and mine effluent (Ni, As, Sb)
Tiivistelmä Tämä väitöskirja käsittelee kolmea erillistä vedenkäsittelyteknologian osa-aluetta: orgaanisten perhappojen käyttöä jäteveden käsittelyssä, orgaanisten jäämien poistoa suolavapaasta kattilalaitoksen lisävedestä ja geopolymeerien sovelluksia vedenkäsittelysorbentteina. Orgaanisten perhappojen pääasialliset edut verrattuna kilpaileviin tekniikoihin ovat hyvä desinfiointiteho, korkea hapetuspotentiaali ja desinfioinnin sivutuotteiden muodostumattomuus. Permuurahais-, peretikka- ja perpropaanihapon vertailu osoitti permuurahaishapon olevan kemikaaleista tehokkain E. coli - ja enterokokkibakteerien inaktivoinnissa kustannus- ja teknisistä näkökulmista. Hapetuksessa, jossa käytettiin bisfenoli-A:ta malliaineena, ei kuitenkaan havaittu etua verrattuna edullisempaan vetyperoksidiin. Ruostumattoman teräksen (316L) pinnalla ei havaittu merkittävää korroosiota, kun taas hiiliteräs ei sovellu käytettäväksi perhappojen kanssa. Orgaaniset jäämät kattilalaitoksen vesi-höyrykierrossa hajoavat termisesti pienen moolimassan hapoiksi ja aiheuttavat korroosioriskin. Aktiivihiilisuodatuksen todettiin olevan soveltuva menetelmä orgaanisten jäämien poistoon lisävedestä. Aktiivihiililaatujen välillä ei havaittu merkittäviä eroja, mutta happopesu aktiivihiilen esikäsittelynä vähensi hiilestä liukenevien epäpuhtauksien määrää. Geopolymeerit ovat zeoliittien amorfisia analogeja ja niiden ioninvaihtokykyä voidaan hyödyntää vedenkäsittelysovelluksissa. Metakaoliini- ja masuunikuonapohjaisten geopolymeerien todettiin olevan lupaavia materiaaleja malliliuosten, kaatopaikan suotoveden ja kaivoksen purkuveden käsittelyssä poistettaessa ammoniumia, nikkeliä, arseenia ja antimonia

Résumé :
Abstract Chemical and oxidative biocides are designed to sanitize water by reducing aerobic and anaerobic bacterial populations in the fresh, brackish and reclaimed source waters. These biocides are used extensively in high-rate fracture stimulations to reduce formation damage, chemical degradation, biogenic H2S and microbial induced corrosion (MIC). Oxidative biocides work by removing electrons from the cell wall of aerobic and anaerobic bacteria. The same electron transfer mechanism can be detrimental to surface equipment. This study presents the impact of several oxidative biocides on the corrosion rate and pitting of different frac iron alloys and how those biocides effect the mechanical integrity of elastomer seals. It also presents different remediation methods to mitigate their oxidative effects. The oxidative biocides tested were Chlorine, Chlorine Dioxide and a Peracidic Acid blend. The corrosion rate of the iron alloys coupons was measured by weight loss analysis. This method can measure the rate of corrosion in pounds per square foot at time and was used to compare the impact of different residual oxidizers on the corrosion rate of the ground iron. Structural changes to the elastomers were detected visually. The results of the study showed that the corrosion rate varied depending on the alloy/residual oxidative biocide combination. Usually, Peracidic Acid blend or Chlorine had the highest corrosion rates across all alloys tested; depending on the oxidative biocide/alloy combination, the corrosion rate could vary by a factor of 2X over the nine-week timeframe. Elastomer testing over 6 weeks showed variability in the types of structural changes depending on the concentration and oxidative biocide tested. The lab and field testing included onsite monitoring of the corrosion rate, oxidation reduction potential (ORP), oxygen in solution and determination of the Langelier Saturation Index (LSI). The methodology has been effective in predicting iron failures related to the composition of the water and/or presence of oxidizers. Chemical solutions implemented to mitigate the surface iron failures included use of intermittent blends of water-soluble quaternary amines and surfactants. Since these remediation attempts have started, the replacement cost of frac iron has decreased from over 550K US$ per month, per frac spread to none, over a 3-month period.
