Abstract
A process for producing 2,6-dimethylnapthalene from 1-(p-tolyl)-2-methylbutane, 1-(p-tolyl)-2-methylbutene or a mixture thereof by dehydrocyclization in the presence of a catalyst, comprising using non-acidic activated carbon as a catalyst.
Claims16
A process for producing 2,6-dimethylnapthalene comprising:
- subjecting 1-(p-tolyl)-2-methylbutane, 1-(p-tolyl)-2-methylbutene or a mixture thereof to a dehydrocyclization reaction in the presence of a catalyst wherein the catalyst is a non-acidic activated carbon to convert 1-(p-tolyl)-2-methylbutane, 1-(p-tolyl)-2-methylbutene or a mixture thereof to 2,6-dimethylnapthalene.
