Regioselective preparation of β-isopropylnaphthalene over superacidic solid or supported perfluorinated sulfonic acid catalysts |
| abstract |
A process for the production of beta -isopropylnaphthalene in high regioselectivity (90-98%) by alkylation of naphthalene over solid or supported superacid catalysts, such as a perfluorinated alkanesulfonic acid of four to eighteen carbon atoms (C4F9SO3H to C18F37SO3H) or a polymeric perfluorinated resin-sulfonic acid, such as the acid form of the commercially available Nafion-K ion-membrane resin (DuPont). Further isomerization of mixtures of isomeric isopropylnaphthalenes to preferentially pure beta -isopropylnaphthalene can also be effected. |
