Abstract

This paper introduced extractive distillation to overcome the drawbacks of conventional distillation in separating dimethyldichlorosilane and methyltrichlorosilane. Based on the prediction of UNIFAC model, this paper adopted vapor-liquid equilibrium experiment for the entrainer selection. Aspen plus was employed to simulate the extractive distillation process to determine the overall energy consumption and separation effect. Simulation results showed that extractive distillation of dimethyldichlorosilane and methyltrichlorosilane was industrially feasible.
