Description

ABSTRACT:
1,1,1-Trichloroethane cannot be completely separated from methanol, ethanol, n-propanol, isopropanol, 2-butanol or t-butanol by conventional distillation or rectification because of the minimum boiling azeotropes. 1,1,1-Trichloroethane can be readily separated from these alcohols by extractive distillation. A typical effective agent is dimethylsulfoxide.
