摘要

Preparing hydroxyalkyl carbamate by reacting alkylene carbonate with an amine comprising ammonia or primary or secondary amines, comprises continuously feeding alkylene carbonate and amine into a reaction chamber, reacting the alkylene carbonate and amine at 20-100[deg] C in the reaction chamber, and continuously separating the resulting hydroxyalkyl carbamate or a mixture of hydroxyalkyl carbamate from the reaction chamber.
