Friedel-Crafts acylation reactions using heterogeneous catalysts stimulated by microwave radiation
Ion exchanged zeolites, ion exchanged clays, sulphated zirconia and silica supported phosphotungstic acid were prepared. Characterisation of the catalysts using pyridine adsorption revealed the catalysts contained both Brønsted and Lewis acid sites. When the catalytic activities for the acylation of...
