Abstract
A method to efficiently and stably produce trifluoroethylene from 1,1,1,2-tetrafluoroethane is provided. In the method, a material gas containing 1,1,1,2-tetrafluoroethane in a gaseous phase and calcium oxide in a solid phase are brought into contact with each other in a reactor. Clogging of the reactor is less likely to occur, the load of the moisture removal process is light, and problems such as a decrease in the yield of trifluoroethylene do not arise.
Claims11
A method for producing trifluoroethylene, the method comprising:
- contacting a material gas comprising 1,1,1,2-tetrafluoroethane and an inert gas with calcium oxide at a temperature of 200 to 500° C. in a reactor,
- wherein a molar ratio of 1,1,1,2-tetrafluoroethane to the inert gas (1,1,1,2-tetrafluoroethane:inert gas) at the contacting is from 20:80 to 100:0, and wherein the inert gas is nitrogen.
