CONTINUOUS PROCESS FOR THE HOT PHOSGENATION OF AMINES

摘要

This invention relates to a process for the production of organic isocyanates by the continous hot phosgenation of amines, whereby the solids are retained in the reactor by an appropriate separator and the isocyanate formed during the reaction is constantly removed from the reactor. Preferably the amount of solids of the suspension in the reactor is set so that the amount of the isocyanate taken off per unit of time reaches a maximum.
