发明名称 Separation of 3-methyl-2-butanol from 2-pentanol by extractive distillation
摘要 3-Methyl-2-butanol is difficult to separate from 2-pentanol by conventional distillation or rectification because of the proximity of their boiling points. 3-Methyl-2-butanol can be readily separated from 2-pentanol by extractive distillation. Effective agents are acetamide or 2,2,2-trichloroethanol.
