ABSTRACT:
Propylene oxide adducts of oxyethylene glycols are used as extractive distillation agents in an extractive distillation column in the distillation of propylene oxide contaminated with water, acetone and methanol to obtain an overhead propylene oxide distillate fraction contaminated with reduced quantities of water, acetone and methanol, and a heavier bottoms distillation fraction containing substantially all of the extractive distillation agent, and acetone and some of the methanol and water introduced into the distillation column.
