Paragraph 0035; 0036; 0070, (2019/04/26)
The invention discloses a fatty alkyl dimethyl benzyl quaternary ammonium salt preparation method, which comprises: carrying out a salt formation reaction on fatty alkyl dimethyl tertiary amine and abenzyl halide in an organic solvent at a temperature of 30-70 DEG C, wherein R in the fatty alkyl tertiary amine is C6H13-C22H45, the halogen in the benzyl halide is chlorine, bromine or iodine, and the organic solvent is one or a plurality of materials selected from methanol, ethanol, n-propanol, isopropanol, acetone and acetonitrile. According to the present invention, the yield of the preparation method is high, and can reach more than 90%; the purity is high, and can achieve more than 99%; the water content is low; the product has good appearance and simple post-treatment effect; and the method can reduce the energy consumption, and is suitable for industrial production.

When organic esters or alcohols were dissolved in each of three novel ionic liquids (which have no effective vapour pressure), the vapour-liquid equilibria (as measured by infrared spectroscopy of the gas phase) revealed significant positive deviation from Raoult's law for a wide range of perfume raw materials. The addition of water amplified the repulsive effect of the ionic liquid matrix, and this was exemplified by a series of ternary phase diagrams.

The parameters which influence the quaternization reaction of some N,N-dimethylalkylamines of RN(CH3)2, type (R = octyl, decyl, dodecyl, tetradecyl and hexadecyl) with benzyl chloride were studied. By thermogravimetric analyses, the kinetic parameters, the reaction order, "n", and the activation energy, "Ea", of the thermal decomposition of the quaternary salts prepared in this study, were established.
