The reactor temperature is raised to 320° C. and the reactor pressure adjusted to 230 psig (1690 kPa). (CF3)2CHCF2OCH3 (ether A, 9.2 g) and a solution of (CF3)2CHCO2H (2.0 g) in water (6 mL) are independently and continuously fed to the reactor over 3 hours. After the feed flow is stopped, the reactor is flushed with deionized water (10 g) . The reactor effluent is scrubbed to remove HF. The product includes both HFC-236fa and CF3CH=CF2 (HFC-1225zc).
