About technically useful properties of esters on the base of alkylaromatic hydrocarbons

Method obtaining of ecologically pure dielectric liquid of acetoxymethyl-secondary hexylo-xylol has been developed. Its electro-physical properties allow considering it as perspective substitute of natural castor oil. Efficiency of acetoxylation stage of chlorine methylation products without prelaminar division has been shown. Carried out distillations at chlorinemethylation stage lead to the formation of significant amount of diarylalkanes and yield dielectric liquid is 72.27%. By involving of diarylalkanes into the acetoxylation stage, decomposition of chlorine methylate is prevented under the influence of high temperatures and yield of dielectric liquid increases up to 87.7%. It has been determined that the reaction chlorine methyl-secondary-hexyl-o-xylol of interaction with sodium acetate in presence of triethylphenmethyl chloride proceeds in conditions of heterogenous interphase catalysis. The yield of the product obtained under heterogeneous catalysis conditions is 98% compared to the yield in the product medium in acetic acid 89.5%. The solidification temperature of the synthesized complex product was -42 °C, which greatly exceeds the castor oil solidification temperature.
