Full textIn recent years, industrial and academic researches have experienced unprecedented changes related to the concept of sustainable development. Health and environment new requirements have prompted chemists to develop chemical products and processes that reduce or eliminate hazardous substances. The research work described in this thesis is focused on the development of new reducing systems using hydrosiloxanes as substitutes for aluminum and boron hydrides. In order to achieve this goal, reducing systems combining 1,1,3,3-tetramethyldisiloxane (TMDS) or polymethylhydrosiloxane (PMHS) with titanium or vanadium complexes have been developed for the reduction of amides and nitriles. The nature of both the association “hydrosiloxane – metal” as well as the studied substrate played an important role on the performance and the selectivity of the reaction. On the one hand, selective reductions of amides (tertiary and secondary) and nitriles to aldehydes were carried out respectively in the presence of titanium(IV) tetraisopropoxide and vanadium(V) triisopropoxide oxide. On the other hand, reductions of amides (primary) and nitriles afforded the corresponding primary amines in the presence of titanium(IV) tetraisopropoxide. Finally, these systems have been applied for the synthesis of saturated N-heterocycles. Reduction of dinitrile compounds led, in one step, to piperidine, pyrrolidine and azetidine derivatives through an intramolecular reductive alkylation reaction

Fatty acid is a carboxylic acid with a long saturated or unsaturated aliphatic chain. It is a main ingredient used in cosmetic products. Part of fatty acids show the antimicrobial efficacy of microorganisms such as bacteria or fungi, but the problem of solubility leads to use of inconvenience. This study utilized 1,1,3,3-tetramethylguanidine to react with different carbon chain length of fatty acid, producing nine 1,1,3,3-tetramethylguanidium aliphatate (TGA). Antimicrobial activity of the TGA was evaluated with (a) disc diffusion assay; (b)minimum inhibitory concentration, (MIC); (c)minimum microbicidal concentration, (MMC) to evaluate the antibacterial capacity. This study showed that the different types of TGA should be dissolved in water. According to our experimental results revealed that the antibacterial activity had not obvious effect in C8~C12 carbon chains of TGA. For example, 1,1,3,3-tetramethylguanidium dodecanoate at 20 mg/mL could inhibit the Staphylococcu aureus and Baccillus Subtilis growth to 23 mm and 22.3 mm of inhibition zones (MIC, 142.6 µg/mL and 189.0 µg/mL ; MMC, 227.3 µg/mL and 254.0 µg/mL, respectively), the inhibition zones of Escherichia coli and Pseudomonas aeruginosa were about 12 mm (MIC >1000 µg/mL, MMC >1000 µg/mL, respectively), the growth inhibition zones was about 11 mm (MIC 325.3 µg/mL and MMC 489.6 µg/mL, respectively) in Candida albicans.

In this study, phase equilibrium conditions for carbon dioxide hydrates in the presence of 2-methoxyethyl ether, tetrabutylammonium hydroxide and 1,1,3,3-tetramethylguanidine were experimentally measured. The three-phase (H-Lw-V) equilibrium pressures and temperatures were determined by isochoric method in the pressure range from 1.68 to 3.44 MPa with various concentrations of the additives. Also, the kinetic behaviors were investigated in the presence of 2-methoxyethyl ether at 0.2 and 0.3 mass fraction. Compared with pure water system, addition of 2-methoxyethyl ether and 1,1,3,3-tetramethylguanidine in the system cause inhibition effect on carbon dioxide hydrate formation and the maximum decrease of dissociation temperature is about 5.7 K and 11.1 K, respectively. On the other hand, addition of tetrabutylammonium hydroxide in the system gives rise to promotion effect on carbon dioxide hydrate formation and the maximum increase temperature is about 11 K, compared with pure water system. To simulate the seawater environment, this study also measured the additives in brine system with 0.035 mass fraction of NaCl. Moreover, the structure and dissociation enthalpy of hydrates are estimated by using Clausius-Clapeyron equation. The structures of carbon dioxide hydrates with addition of 2-methoxyethyl ether and 1,1,3,3-tetramethylguanidine are both classified as structure I, whereas those with addition of tetrabutylammonium hydroxide are classified as structure TS-I. In this study, the kinetics of carbon dioxide hydrate with 2-methoxyethyl ether as the additive at 0.2 and 0.3 mass fraction were also investgated. With an increase in initial operating pressure, the driving force increased. That is due to the fact that higher initial pressure created higher supersaturation, which induced stronger driving force. At 0.3 mass fraction of 2-methoxyethyl ether in the system, the induction time was shortened as the driving force increased. In addition, the carbon dioxide consumption was increased almost linearly with increasing the driving force. However, the average hydrate formation rate stayed almost constant with the increased driving force. Also, addition of 2-methoxyethyl ether at 0.2 mass fraction in the system was studied. The results showed the induction time was shortened in comparison to that of 0.3 mass fraction. However, the average hydrate formation rate and carbon dioxide consumption were not effectively influenced.
