摘要：采用萃取精馏法对甲醇－碳酸二甲酯二元恒沸物进行了分离；得到了适宜的萃取剂，研究了萃取剂的配比和回流比对分离性能的影响，并考察了萃取剂的回收和循环使用对分离性能的影响。
The separation of azeotrope formed by methanol and DMC has been investigated by extractive distillation. The better extractant has been selected. The effects of extractant ratio and reflux ratio on the separation have been investigated. The better extractant and reflux ratio have been determined, and the recycle and the recovery of extractant have been studied.
