摘要 |
A process for the production of (cyclo)aliphatic diisocyanates and triisocyanates comprises phosgenation of the corresponding diamine or triamine in the gas phase. A process for the production of (cyclo)aliphatic diisocyanates and triisocyanates of formula R-(NCO)n (1) comprises phosgenation of the corresponding diamine or triamine of formula R-(NH2)n (2) in the gas phase whereby the (cyclo)aliphatic amine vapor, and phosgene are separately heated at 200-600 degrees C and continuously fed to a reaction chamber without moving parts and having a constriction in the walls in the region of the reaction zone. R = upto 15C (cyclo)aliphatic; n = 2 or 3.
