Procedure

The test procedure described in Example 2 was repeated except that the catalyst was 0.5% Pd on alumina, the reaction temperature was held to approximately 150° C. and the duration of the test was approximately 12.6 hours. The mole ratio of hydrogen to CF3CCl2CF2Cl introduced into the quartz reactor was approximately 1.09. The reaction product was collected and its composition was determined. The reaction resulted in a conversion of CF3CCl2CF2Cl of about 97.8%, with a selectivity for CF3CH═CF2 of 6.8%, for CF3CCl═CF2 of 85.4%, and for CF3CHClCF2Cl of 3.8%.
