发明名称 Dehydration of 2-methoxyethanol by extractive distillation
摘要 2-Methoxyethanol cannot be completely separated from water by conventional distillation or rectification because of the minimum boiling azeotrope. 2-Methoxyethanol can be readily separated from water by extractive distillation. Effective agents are dimethylsulfoxide, sulfolane, dimethylformamide or 1,4-butanediol.
