The performance of the Cr-Mg-Zn catalyst which is prepared by mechanical mixing for synthesis of 1,1,1,2-tetrafluoroethane(HFC-134a) from reaction of 1,1,1-trifluoro-2-choroethane (HCFC-133a) with AHF is investigated.

• 采用共混法制得Cr-Mg-Zn催化剂,以HCFC-133a(1,1,1-三氟-2-氯乙烷)与无水HF合成HFC-134a(1,1,1,2-四氟乙烷)为目标反应,考察了不同条件下该催化剂的性能。
