Calculation of the Kinetic Parameters of the Modification
Reaction of Polyisobutylene With Acrylonitrile
Abstract
In the article, the results of the research on the calculation of the mathematical model and parameters of the copolymer production process by modifying polyisobutylene with acrylonitrile polar monomer at a temperature of 20-600C in the presence of AlCl3 catalyst have been reflected. Using this, the results of the study of the effect of polyisobutylene with acrylonitrile on the reaction conditions have been given, the kinetic equations of those reactions have been calculated, the values of the parameters, the analysis of the researches in the field of mathematical modeling of the process were reflected. This method allows us to reduce the number of experiments, resources and time, and also to obtain an arbitrary ratio of acrylonitrile to polyisobutylene that satisfies us within the limits of experimental parameters. The functional dependence between those parameters has been drawn up by analyzing the regularities of the ratio of the solidities of [AN] and [PIB] in the copolymer on temperature, reaction time, and the solidities of PIB, AN and the catalyst (AlCl3) in the initial solution. The kinetic parameters of the PIB modification reaction with AN have been calculated on the basis of the developed kinetic model and experimental materials. The rate constants of the reactions corresponding to the temperatures of 20, 40, 600C for 1.8% (mass) catalyst amount are 0.7699; 0.8322 and 0.89 s-1 have been obtained. The rate constants corresponding to those temperatures and 0.92% amount of catalyst were 0.2976, 0.3288, 0.3581s-1. The effect of the amount of catalyst on the activation energy has also been studied; E=3000 C/mol. (AlCl3=1.8%) (mass) and E=3750 C/mol. (AlCl3=0.92%).
