Characterization and Catalytic Activity of CuCl2-Al2O3Ethylene Oxychlorination Catalysts

CuCl2/Al2O3ethylene oxychlorination catalysts have been characterized by using IR spectroscopy of the surface hydroxy-groups and of adsorbed pyridine and CO2. The ethylene oxychlorination reaction to 1,2-dichloroethane has been investigated by using pulse reactor studies andin-situIR experiments in...

Summary:CuCl2/Al2O3ethylene oxychlorination catalysts have been characterized by using IR spectroscopy of the surface hydroxy-groups and of adsorbed pyridine and CO2. The ethylene oxychlorination reaction to 1,2-dichloroethane has been investigated by using pulse reactor studies andin-situIR experiments in static conditions. The results allowed emphasizing the negative role of uncovered alumina surface, evidenced by IR experiments, considered to be responsible for the dehydrochlorination of 1,2-dichloroethane with a consequent loss in selectivity that is very important in low Cu-loading samples.
