Research of electric conductivity of esters of (C4-C10) terminal dicarboxylic acids depending on their chemical structure

Using a teraohmmeter, the resistance indices of synthesized symmetric, asymmetric and complex esters of terminal dicarboxylic acids (TDA) of various structures were determined. The specific resistance and electrical conductivity of the obtained samples were determined. The properties of electrical conductivity are investigated depending on the structure of diesters and complex esters of TDA. It was found that in complex esters of TDA containing 3 or 4 ester groups, with an increase in the length of the carbon chain in the acid molecule, the electrical conductivity decreases. It was revealed that symmetric, asymmetric and complex esters of succinic acid, complex ester of adipic acid (based on octanol-1, ethylene glycol and caproic acid) and dibenzyl ester of sebacic acid have relatively good electrical conductivity.
