| description | PROBLEM TO BE SOLVED: To provide a method for chlorinating an alkylaromatic hydrocarbon, comprising chlorinating the alkylaromatic hydrocarbon such as toluene in the presence of a Lewis acid catalyst, by which the production rate of the 2, 6- substituted compound in the obtained nucleus-dichlorinated isomer mixture can be increased to profitably produce the 2, 6-substituted compound. SOLUTION: This method for chlorinating the alkylaromatic hydrocarbon, comprising chlorinating the alkylaromatic hydrocarbon in the presence of a Lewis acid catalyst to produce the nucleus-disubstituted isomer mixture, characterized by carrying out the first chlorination reaction in the presence of one or more Lewis acid catalysts selected from stannic chloride (SnCl4) and titanic chloride (TiCl4) and then performing the second chlorination reaction in the presence of one or more Lewis acid catalysts selected from aluminum chloride (AlCl3), gallium chloride (GaCl3), ferric chloride (FeCl3) and antimony chloride (SbCl5). |
