Abstract

Mesoporous alumina which contains only Lewis acidity was synthesized by sol-gel method and was then impregnated with sulfuric acid to generate Bronsted ¨ acidity. The catalyst was used in Friedel-Crafts alkylation of resorcinol with methyl tert-butyl ether to produce 4-tert-butylresorcinol and 4,6-di-tert-butylresorcinol as the major and minor products respectively. It was demonstrated that Lewis and Bronsted acidities play a synergetic role in this reaction.
