Versuchsvorschrift

Activated carbon (25 g, 1/8" (0.32 mm) diameter pellets) and deionized water (20 g) are loaded into a 1" (2.54 cm) OD×12" (30.5 cm) length Inconel™ 600 nickel alloy tube. The reactor temperature is raised to 250° C. and the reactor pressure adjusted to 0 psig (101 kPa). (CF3)2CHCF2OCH3 (ether A, 21.5 g) and a solution of (CF3)2CHCO2H (1.8 g) in water (10 mL) and tetrahydrofuran (20 mL) are independently and continuously fed to the reactor over 5 hours. The reactor effluent is scrubbed to remove HF. The product includes HFC-236fa and CF3CH=CF2 (HFC-1225zc).
