Additives are important components of PVC composites, providing polymer modification and retention of its properties throughout the entire period of operation. The development and application of environmentally friendly adipate plasticizers is urgent. The article presents the results of kinetic studies of the esterification of adipic acid with ethoxylated n-butanol of varying degrees of ethoxylation. The effect of various catalysts on the yield of the target ester and the degree of ethoxylation on the rate of the esterification reaction was studied. A mathematical model of the kinetics of the process of obtaining dibutoxyethyl adipates of various degrees of ethoxylation has been developed, which makes it possible to predict the technological indicators of the efficiency of the acid catalyst and the effect of the degree of ethoxylation of the alcohol used. Keywords: adipate plasticizer; kinetics; mathematical model; polyvinyl chloride; prediction; esterification.
