Resumo:

Ion/molecule reactions of C2H3Cl+ have been studied in a mixture of vinyl and ethyl chlorides. The ionic processes have been followed using two mass spectrometers; one is based on the ionic cyclotronic resonance (ICR) while the other is based on photo-ionization at high pressure. The results obtained on these two instruments are complementary and they indicate that the ion C2H3Cl+ does not react directly with ethyl chloride. However, the ions C4H3Cl+ and C4H6Cl+, which are formed following the decomposition of the excited ion-dimer of vinyl chloride, do react with ethyl chloride in a series of condensation reactions involving in each step an elimination of HCl or of Cl. In a mixture of the two chlorides, the most important ions are the C8H13+ and C8H14+; at a pressure of 1 Tonr, their total intensity is equal to 50%. Keywords: ion/molecule reactions of C2H3Cl+, vinyl and ethyl chloride mixtures, mass spectrometry. [Journal translation]

Resumo:

Poly(vinyl chloride) suffers from degradation through oxidation and decomposition when exposed to radiation and high temperatures. Stabilizers are added to polymeric materials to inhibit their degradation and enable their use for a longer duration in harsh environments. The design of new additives to stabilize poly(vinyl chloride) is therefore desirable. The current study includes the synthesis of new tin complexes of 4-methoxybenzoic acid and investigates their potential as photostabilizers for poly(vinyl chloride). The reaction of 4-methoxybenzoic acid and substituted tin chlorides gave the corresponding substituted tin complexes in good yields. The structures of the complexes were confirmed using analytical and spectroscopic methods. Poly(vinyl chloride) was doped with a small quantity (0.5%) of the tin complexes and homogenous thin films were made. The effects of the additives on the stability of the polymeric material on irradiation with ultraviolet light were assessed using different methods. Weight loss, production of small polymeric fragments, and drops in molecular weight were lower in the presence of the additives. The surface of poly(vinyl chloride), after irradiation, showed less damage in the films containing additives. The additives, in particular those containing aromatic (phenyl groups) substitutes, inhibited the photodegradation of polymeric films significantly. Such additives act as efficient ultraviolet absorbers, peroxide quenchers, and hydrogen chloride scavengers.

Poly(vinyl chloride) (PVC) suffers from photo-oxidation and photodegradation when exposed to harsh conditions. Application of PVC thus relies on the development of ever more efficient photostabilizers. The current research reports the synthesis of new complexes of tin and their assessment as poly(vinyl chloride) photostabilizers. The three new complexes were obtained in high yields from reaction of 4-(benzylideneamino)benzenesulfonamide and tin chlorides. Their structures were elucidated using different tools. The complexes were mixed with poly(vinyl chloride) at a very low concentration and thin films were made from the blends. The effectiveness of the tin complexes as photostabilizers has been established using a variety of methods. The new tin complexes led to a decrease in weight loss, formation of small residues, molecular weight depression, and surface alteration of poly(vinyl chloride) after irradiation. The additives act by absorption of ultraviolet light, removal the active chlorine produced through a dehydrochlorination process, decomposition of peroxides, and coordination with the polymeric chains. The triphenyltin complex showed the greatest stabilizing effect against PVC photodegradation as a result of its high aromaticity.

During organochlorine wastes thermal utilization formed at direct chlorination of ethylene to 1,2-dichloroethane in the production of vinyl chloride at Karpatnaftohim LLC, the ash is formed, which clogs gas pipelines and heat exchange elements of the steam generator, causes disruption of normal technological process and leads to emergency shutdowns.The composition of this ash was determined by chemical methods of quantitative analysis and flame photometry for such macrocomponents as Fe2O3 (28%) and FeCl3 (5%), as well as magnesium chlorides (30%) and sodium (4%), the rest (about 32% ) probably resinous highly chlorinated unburned components of VAT residues, carbon particles and nitric acid-insoluble iron compounds. Utilization methods and possible ways to reduce the amount of ash from the organochlorine waste combustion formed at the production of vinyl chloride are briefly considered.

The l-proline-catalyzed reaction of enolizable α,β-unsaturated aldehydes with N-chlorosuccinimide (NCS) gave the corresponding 4-substituted 2,4-dichloro-2-butenals with moderate yields and excellent diastereoselectivities (Z/E = >20/1) through consecutive double chlorination at the α- and γ-positions of the dienamine intermediate. The corresponding 2,4-dichloro-2-butenals contain a multireactive 1,3-dichloro allylic unit useful for the construction of Z-vinyl chlorides; the chloride on the allylic position was replaced with mild nucleophiles such as MeOH and EtOH via an SN2 substitution reaction, and its aldehyde moiety was used as a synthetic handle and transformed into an alcohol or a vinyl group. All products obtained after those synthetic manipulations maintained excellent diastereoselectivities (Z/E = >20/1).

The review paper considers main regularities of the hydrogen chloride oxidation (the Deacon reaction) and oxidative chlorination of methane and ethane. The most efficient catalysts for these processes were shown to be the copper chloride systems on various supports, which contain also chlorides of alkaline and rare-earth metals that decrease the carry-over of the active phase from the catalyst surface and increase the activity. The main kinetic and technological regularities of the oxychlorination processes were considered. The conditions that promote an increase in the yield of target products – lower chloromethanes at oxychlorination of methane and vinyl chloride at oxychlorination of ethane – were revealed. Variants of technological schemes for the oxychlorination processes were proposed.

Resumo:

Recently, vinyl chlorides has been increasingly used as electrophilic partners in various cross-coupling reactions. In contrast to inaccessible and expensive vinyl bromides and iodides, in many cases vinyl chlorides are highly active in the presence of not only traditional palladium complexes, but also economical and safe compounds of iron, cobalt and nickel. Earlier, we reported on the development of new approaches to the getting of stereochemically pure (E)- and (Z)-vinyl chlorides and their successful use at the synthesis of medicines and insect pheromones. Continuing this work, an effective method of the synthesis of (E)- and (Z)-isomers of 2-(3-chloroprop-2-en-1-yl)cyclohexanone - convenient precursors of 2-(alk-2-en-1-yl)cyclohexanones, known flavors and intermediates in the synthesis of polycyclic compounds was developed. In the reaction of ethyl 2-oxocyclohexanecarboxylate with the (E)- and (Z)-isomers of 1,3-dichloropropene under the phase-transfer catalysis conditions in the presence of K2CO3, the corresponding (E)- and (Z)-isomers of ethyl 1-(3-chloroprop-2-en-1-yl)-2-oxocyclohexanecarboxylate were obtained in high yields (80-86%), without allyl rearrangement. The complete retention of the configuration of the chlorovinyl group is observed. Standard methods of the decarboxylation of isomers of ethyl 1-(3-chloroprop-2-en-1-yl)-2-oxocyclohexanecarboxylate under acidic or basic conditions result in very average yields of the corresponding chlorovinyl ketones. The best results were obtained by their decarbalkoxylation in slightly modernized Krapcho conditions. Carrying out reaction in N-methylpyrrolidone at 140-150 °C in the presence of 3 eq. LiCl and 2 eq. of H2O leads to individual (E)- and (Z)-isomers of 2-(3-chloroprop-2-en-1-yl)cyclohexanone in 79-82% yields and a stereochemical purity of ~ 99%. The structure of the obtained compounds were confirmed by HRGC, NMR, and GC/MS data. The configuration of the vinyl group was proved by the coupling constants of the vinyl hydrogens, equal to 13.2-13.4 and 7.0-7.3 Hz for the (E)- and (Z)-products, respectively, as well as by the downfield shift of the allyl carbon atom of trans-isomers by ~4 ppm as compared to the cis-analogs.

Resumo:

The catalytic mechanism and activation energies of metal chlorides RuCl3, AuCl3, and BaCl2 for 1,2-dichloroethane (DCE)-acetylene exchange reaction were studied with a combination of density functional theory (DFT) calculations and experiments. Two reported reaction pathways were discussed and acetylene-DCE complex pathway was supported through adsorption energy analysis. The formation of the second vinyl chloride monomer (VCM) was proven to be the rate-determining step, according to energy profile analysis. Activity sequence of BaCl2 > RuCl3 > AuCl3 was predicted and experimentally verified. Furthermore, reversed activity sequences of this reaction and commercialized acetylene hydrochlorination reaction were explained: the adsorption abilities of reactants are important for the former reaction, but chlorine transfer is important for the latter.
