Process for the preparation of 2,6 dimethylnaphthalene

摘要

The present invention concerns a process for preparing 2,6-dimethylnaphthalene which comprises subjecting 1,6 and/or 1,5-dimethylnaphthalene, optionally mixed with other isomers of dimethylnaphthalene, to isomerization, which comprises treating said compounds at a temperature ranging from 100 to 400 DEG C, under at least partially liquid phase conditions, in the presence of an MTW zeolite.
