PROBLEM TO BE SOLVED: To provide an oxychlorination catalyst for producing 1,2-dichloroethane from ethylene, hydrogen chloride and oxygen with high selectivity and stably.SOLUTION: An oxychlorination catalyst is provided which has a hollow cylindrical shape carrying at least copper chloride and a chloride of a periodic table group 1 element on an alumina carrier. The oxychlorination catalyst has pores whose pore diameter is settled within the range from 3 nm and less than 15 nm and pores whose pore diameter is settled within the range of 15 to 50 nm, and a standard deviation of a molar ratio of the chloride of the periodic table group 1 element with respect to copper chloride is 0.1 or less. |
