Abstract:
Disclosed is a method of simultaneously preparing 1,1,1-trifluoro-2-chloropropene and 1,1,1,2-tetrafluoropropene, the method including i) a step of elevating a temperature of a reactor charged with a gas phase catalyst up to a reaction temperature; ii) a step of feeding 1,1,1-trifluoro-2,3-dichloropropane and 2-chloro-1,1,1,2-tetrafluoropropane into the reactor, the temperature of which has been elevated; iii) a step of performing dehydrochlorination while maintaining the temperature of the reactor; and iv) a step of performing washing and distillation after the dehydrochlorination. In accordance with the present disclosure, a high-efficient gas-phase process of continuously, simultaneously preparing 1,1,1-trifluoro-2-chloropropene and 1,1,1,2-tetrafluoropropene is provided.

Claim (Index 5):
