Process for producing 2,6-dimethylnaphthalene.

摘要

There is dislosed 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 cyclization dehydrogenation reaction in the presence of a catalyst comprising a (a) palladium component, a (b) alkali or alkaline earth metal compound and (c) aluminum oxide. The above process enables the production of highly pure 2,6-dimethylnaphthalene in a high yield at a low cost by using the catalyst having high safety and stability from the widely available starting materials.
