VERFAHREN ZUR KONTINUIERLICHEN HERSTELLUNG VON ORGANISCHEN MONO- ODER POLYISOCYANATEN |
摘要 |
Organic mono- or poly-isocyanates are produced on a continuous basis by phosgenating the corresponding amines. A solution of the amine to be phosgenated is continuously sprayed through a smooth-jet nozzle into a solution of phosgene continuously flowing through a mixing chamber. The mixing chamber is maintained at a temperature of 120 DEG to 300 DEG C. and a pressure of from 10 to 1000 bars. The molar ratio of phosgene to primary amino groups is generally from 2:1 to 30:1. |
