Friedel-crafts alkylation of resorcinol over mesoporous alumina loaded with sulfuric acid
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-d...

| Summary: | 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. |
