In this work are developed the basic electrophysical properties of the ester- acetoxymethyl-sec.hexyl-o-xylene; methods for its purification and stabilization. There were chosen the adsorption method of thermo-oxidative stabilization to clean dielectric fluid from conductive impurities. As a result of The electrophysical characteristics of the acetoxymethyl-sec.hexyl-o-xylene ester, as well as the method of its purification using alumina, and hydrogenation on a catalyst representing 0.2% palladium on alumina and stabilization using additives NG-2246. As a result of the research, it was possible to obtain an ester with improved electrophysical parameters.
