摘要
The present invention relates to a method for preparing dimethyl carbonate and ethylene glycol by using a pre-reactor, and more particularly, dimethyl carbonate (ethylene carbonate) and methanol (methanol) by reacting in a reaction distillation column In the continuous process of combining dimethyl carbonate and ethylene glycol, conventional reaction by reacting ethylene carbonate and methanol as reactants in a pre-reactor that can easily change the reaction conditions such as temperature before the reaction distillation column It is possible to improve the production speed of the product by supplementing the disadvantages of the distillation method, as well as to properly distribute the amount of unreacted methanol circulated to the pre-reactor and the reaction distillation column, which is improved to enable the optimal production of dimethyl carbonate and ethylene glycol. Dimethylcarbone using reactor It relates to a process for the production of whey and ethylene glycol.;Dimethyl carbonate, ethylene glycol, reaction distillation, pre-reactor, reaction temperature
