ABSTRACT:
An extractive distillation agent consisting essentially of 2-hydroxyethyl 2-hydroxyethylcarbamate, and is fed to an extractive distillation column used for the distillation of propylene oxide contaminated with water to obtain an overhead distillate fraction consisting of essentially anhydrous propylene oxide, and a heavier bottoms distillation fraction containing substantially all of the 2-hydroxyethyl 2-hydroxyethycarbamate, and water introduced into the disillation column.
