摘要
通过萃取精馏、精馏对甲醇、丙酮与乙酸乙酯的混合溶媒加以分离,通过对生产数据的调整,确定了萃取精馏过程中混合溶媒与萃取水加入比例为1∶1,此条件下,萃取效果最好。萃取塔顶可以得到丙酮与乙酸乙酯和水的共沸物,塔底可以得到纯度为99.5%的甲醇。
To separate the mixture solvent including methanol,acetone and ethyl acetate by extractive distillation and distillation.Through adjusting production data,to determine the ratio of the mixture solvent to water was 1∶1 in the the extractive distillation process,and under the conditions,the extraction results were the best.To obtain the azeotrope including acetone ethyl acetate and water in the top of the tower,99.5% methanol in the bottom.
