ABSTRACT:
High purity hydroxyalkyl carbamates having alkyl groups with two, or three or more carbon atoms may be produced from anhydrous ammonia and alkylene carbonates at relatively low pressures, such as in a low pressure conventional kettle process. In this method, a reactor vessel is typically evacuated prior to reaction and anhydrous ammonia and alkylene carbonates are typically reacted in the presence of an initiator. Using this method, hydroxypropyl carbamate products having a purity greater than about 97%, and hydroxybutyl carbamate products having a purity greater than about 95% may be produced. Hydroxybutyl carbamate compositions comprising mixtures of 2-hydroxylbutyl carbamate and 1-hydroxymethyl propyl carbamate may also be produced.
