Abstract
N- and O-substituted carbamates are prepared by reacting urea with an aminopropanol at 140.degree. C. or above. The compounds obtained by the novel process are useful starting materials for the preparation of textile finishing agents, stabilizers, plasticizers, dyes and crop protection agents.
