Abstract
The present invention provides a process of catalytic fluorination in gas phase of product 1,1,1,2,3-pentachloropropane or/and 1,1,2,2,3-pentachloropropane into product 2-chloro-3,3,3-trifluoropropene in presence of a catalyst and oxygen.
Claims21
A catalytic fluorination process comprising introducing reactants comprising 1,1,1,2,3-pentachloropropane and/or 1,1,2,2,3-pentachloropropane, HF, and oxygen in the gas phase into a reaction zone containing a catalyst to yield 2-chloro-3,3,3-trifluoropropene, wherein oxygen is introduced in an amount from 0.5 to 10 mole % of oxygen per pentachloropropane molecule, wherein no stabilizer is introduced to the reactor, and wherein conversion is 100% for at least 86 hours.
