The researching content was as follows: 1. When AlClx/HY zeolite be used as catalyst, the effects of the ratio of 2-methylnaphthalene to tetramethyl benzene, catalyst concentration, reaction temperature and reaction time on the conversion (based on 2-methylnaphthalene), yield and selectivity (both based on 2,6-DMN) were discussed. In addition, by orthogonal experiment, the optimum reaction conditions were determined at the same time. The optimum reaction conditions : the molar ratio of 2-methylnaphthalene and tetramethyl benzene =1:1, reaction temperature was 400℃.
