ABSTRACT:
Acetamidoethylene is isolated from acetamidoethylene-containing mixtures by distillation with enhanced efficiency when a high-boiling liquid, especially glycerol, is added to the mixtures prior to or during said distillation. This invention is particularly effective at separating acetamidoethylene from mixtures additionally containing acetamide, especially preparation products.
