Tetrafluoropropene production processes
View Patent ↗A process is disclosed for producing 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene. The process involves pyrolyzing 1,1,1,2,3-pentafluoropropane.
1. A process comprising pyrolyzing 1,1,1,2,3-pentafluoropropane to 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene wherein said pyrolyzing is carried out at a temperature from about 650° C. to about 900° C.
2. The process of claim 1 wherein said pyrolyzing is carried out to a single-pass conversion of said 1,1,1,2,3-pentafluoropropane of at least about 50%.
3. The process of claim 1 wherein said pyrolyzing is carried out at a temperature from about 650° C. to about 850° C.
4. The process of claim 1 wherein said pyrolyzing is carried out at a near atmospheric total pressure.
5. The process of claim 1 wherein said pyrolyzing is carried out for a reaction time of about 0.5 to 60 sec.
6. The process of claim 1 wherein said pyrolyzing is carried out in the presence of unreactive diluent gas.
7. The process of claim 6 wherein said unreactive diluent gas is selected from the group consisting of nitrogen, argon, helium.
8. The process of claim 1 wherein said pyrolyzing is carried out in a reactor which is substantially empty.
