Abstract
The present disclosure relates to a new and efficient manufacturing process for the production of HFC-1225ye. The process involves contacting at least one hexafluoropropane selected from the group consisting of 1,1,1,2,2,3-hexafluoropropane and 1,1,1,2,3,3-hexafluoropropane with a suitable catalyst in a reactor to obtain a product mixture containing HFC-1225ye (1,2,3,3,3-pentafluoropropene) where the pressure in the reactor ranges from about 0.5 psig to about 100 psig.
