Increased efficiency of empirical models to predict the kinetics of extraction of the plasticizer from the tank on the basis of polyvinyl chloride that has achieved the introduction of a complex parameter, eliminating the dependence of the coefficient of the model from the thickness of the tank and extraction conditions. The complex parameter provides the use of experimental results of different works on the basis of which the receipt depending on a complex parameter on the temperature of the extractant at a certain content of plasticizer and from the initial plasticizer content at a certain temperature of the extractant.
