The study and modeling of cyclocarbonylation reactions for chlorinated epoxy resins with applying Calvet calorimetry

Abstract

The methodology and results of cyclocarbonylation kinetic study for chlorinated epichlorohydrine oligomers with sodium bicarbonate are presented. Calvet calorimetry is applied as the main kinetic research technique. Correlation between heat production and epichlorohydrine groups conversion has been established. A mathematical model of the cyclocarbonylation reaction in a two-phase “solid–liquid” system has been developed. The proposed model takes into account mass transfer phenomena between the two phases as well as chemical reactions in the liquid reaction phase. The mathematical model kinetic parameters were determined in the result of solving an inverse kinetic task with applying heat production experimental data together with product concentrations data. The model developed in course of the work was used to determine the optimal conditions for running cyclocarbonylation process.
