An aluminum halide complex of an aluminum halide, a hydrogen halide and an alkylbenzene is prepared by continuously feeding a gaseous hydrogen halide to a reaction zone comprising aluminum and an alkylbenzene and continuously taking the resulting aluminum halide complex out of the reaction zone, the byproduced hydrogen gas being taken out of the reaction zone, and aluminum and the alkylbenzene being fed continuously or intermittently to the reaction zone. |
