ABSTRACT:
4-Methyl-2-pentanol cannot be separated from 3-methyl-1-butanol by distillation because of the closeness of their boiling points. 4-Methyl-2-pentanol can be easily separated from 3-methyl-1-butanol by extractive distillation. Effective agents are dodecane, dimethylformamide and dimethylsulfoxide.
