Procedure

(CF3)2CHCF2OCH3 (ether A, 7.1 g) and a solution of (CF3)2CHCO2H (0.6 g) in water (10 mL) are independently and continuously fed to the reactor over 5 hours. The reactor is preheated to 450° C. and maintained at this temperature throughout the run. The reactor pressure is maintained at about atmospheric pressure. The reactor effluent is scrubbed to remove HF. The product includes CF3CH=CF2 (HFC-1225zc) and HFC-236fa.
