Separation of the Ternary System of Methanol/ Methyl Butyl Ether/1-Butylchloride

摘要

The separation of ternary methanol/methyl butyl ether/1-butylchloride mixtures was inves- tigated, which are the main components of the waste liquid. After preliminary studies on the ternary system, the integrated process of extraction and distillation was put forward to separate the ternary system. The results show that methanol can be removed from the mixtures by extraction using wa- ter as the extracting agent. Through distillation of extract and dried raffinate respectively, methanol, methyl butyl ether and 1-butylchloride can be separated and recovered. In addition, the optimal vol- ume for the extracting agent and effects of reflux ratio on the yield of product were also studied. The optimal volume ratio of the extracting agent to material is 1:3:5, and the yield of the product increa- ses with the increase of reflux ratio.
