PROCESS FOR THE PREPARATION OF ISOCYANATES IN THE GAS PHASE |
摘要 |
Isocyanates are produced by reacting a primary amine with phosgene in the gas phase. In this process, the amine is vaporized and then superheated prior to introduction into the reactor. The amine is superheated to a temperature at least 10° C. above dew point before entry into the reactor. A pressure difference between the vaporizer and entry into the reactor of from 1 to 500 mbar is maintained.
