반응 단계

HCFC-225cb was reduced using the reactor and procedures of Example 2 except that the catalyst was prepared from 0.5% Pd/alumina mixed with 50 cc glass helices. The organics flow rate was 4 cc/hr. with a hydrogen flow rate of 90±10 cc/min. The temperature was maintained at 190°±3° C. for 144 hours. HFC-245ca in an 87-92% selectivity and greater than 98% conversion of HCFC-225cb resulted. As the data from Example 4, shown on Table I below indicate, the Pd/alumina catalyst is stable for 144 hours towards the reduction of HCFC-225cb to HFC-245ca.
