PROCESSO PARA A PRODUCAO DE UM CARBAMATO POLIMERICO

摘要

A process for the production of polymeric carbamate from polyalkylene polyamines which provides for the efficient separation of the product mixture into a hydrocarbon phase containing the carbamate and a polyamine phase containing the polyamine hydrochloride salt utilizes an excess of polyamine reactant containing a limited amount of water. The process is particularly suited to the production of monocarbamate.
