Catalytic Production Processes for Making Tetrafluoropropenes and Pentafluoropropenes

Abstract

A process is disclosed for making CF3CF═CHF. The process involves contacting at least one hexafluoropropane selected from the group consisting of CF3CF2CH2F and CF3CHFCHF2 with a chromium oxyfluoride catalyst in a reactor to obtain a product mixture comprising CF3CF═CHF, and recovering CF3CF═CHF from the product mixture. A process is disclosed for making CF3CH═CHF. The process involves contacting CF3CH2CHF2 with a chromium oxyfluoride catalyst in a reactor to obtain a product mixture comprising CF3CH═CHF, and recovering CF3CH═CHF from the product mixture. A process is disclosed for making CF3CF═CH2. The process involves contacting CF3CF2CH3 with a chromium oxyfluoride catalyst in a reactor to obtain a product mixture comprising CF3CF═CH2, and recovering CF3CF═CH2 from the product mixture.
