Modeling and optimizing the process of modifying chlorine-containing epoxy resins using butanediol

The results of an investigation of the modification kinetics of chlorine-containing epoxy resins by 1,4-butanediol in the presence of alkali catalyst have been considered. Experimental investigations have been carried out using a Setaram C80 calorimeter of heat flow in combination with analytical methods for determining initial and final functional groups. The link between conversion and the heat effect was set. A two-phase kinetic model of the modification process was proposed. The parameters of the proposed model have been determined from the condition of minimum disagreement between the experimental and calculated data using nonlinear programming methods in order to find the minimum. The task of finding the optimal temperature profile has been set and solved. A scheme of process control for maintaining the optimal temperature has been proposed.
