Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mono-nuclear chlorination process for an alkylaromatic hydrocarbon with reduced formation of poly-nuclear chlorinated by-products, as a high O/P ratio and high chlorine utilization are retained and a catalyst for mono-nuclear chlorination to be used in this process. SOLUTION: When an alkylaromatic hydrocarbon is mono-nuclear chlorinated with a chlorine gas, a chloride of an element in the group Va in the periodic table is used as a nuclear chlorination catalyst. The catalyst is used in this mono-nuclear chlorination of an alkylaromatic hydrocarbon and mainly comprises a chloride of an element in the group Va in the periodic table.
