Improved method for producing monoisocyanates and oligoisocyanates |
| abstract |
The present invention relates to a process for the preparation of aliphatic, cycloaliphatic, araliphatic and aromatic mono- and oligoisocyanates by phosgenation of the corresponding primary amines at atmospheric pressure, which comprisesa) introducing a catalytic amount of a monoisocyanate (isocyanate a) into an inert solvent together with phosgene;b) adding the primary amine, andc) reacting the resulting reaction mixture with phosgene. |
