摘要 |
PURPOSE: A dimethylnaphthalene, especially 2,6-dimethylnaphthalene is prepared by transmethylating a mixture of naphthalene and 2-methylnaphthalene in the presence of a lewis acid catalyst. CONSTITUTION: A method for preparing 2,6-dimethylnaphthalene comprises reacting a mixture of naphthalene and 2-methylnaphthalene at the mixing ratio of 0.03 to 20 with tetramethylbenzene in the presence of aluminum chloride as a catalyst in a halogenated hydrocarbon solvent at the room temperature, the halogenated hydrocarbon solvent being selected from the group consisting of dichloromethane, benzyl chloride, and mixtures thereof.
