Title:
METHOD FOR REMOVING WATER AND AMMONIA FROM EFFLUENT FROM BENZOPHENONE IMINE REACTOR
Document Type and Number:
Japanese Patent JPH10130218
Kind Code:
A
Abstract:
To produce a stable benzophenone imine free from a reverse reaction to form benzophenone during storage by distilling ammonia and also removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reaction.
This method is composed of the processes distilling ammonia and removing water using distillation or using non-distillation means from an effluent of a benzophenone imine reactor generated by catalytic reaction of a benzophenone of the formula [R1 and R2 are independently a halogen, hydroxy, a 6-10C aryl, a 1-12C alkyl, etc.; (m) and (n) are each independently an integer of 0-5] and ammonia. The distillation is preferably carried out at 20-200°C under a pressure of 1-1,000 mbar.
