摘要：
A process for efficiently producing 2,6-dimethylnaphthalene which comprises subjecting 2-methyl-1-(p-tolyl)butene and/or 2-methyl-1-(p-tolyl)butane as the starting raw material to a cyclization dehydrogenation reaction in the presence of a catalyst comprising (a) a palladium component, (b) an alkali or alkaline earth metal compound and (c) aluminum oxide. The process enables the production of highly pure 2,6-dimethylnaphthalene in a high yield at a low cost. The catalyst used in the process affords high safety and stability.
