A hybrid system bases on silica-alumina and Keggin heteropolyacids as catalyst in the suitable 2-(2-furyl)-chromones and chromanones synthesis
Molybdophosphoric acid/silica-alumina composites are synthesized a through a process described, in which the heteropolyacid was impregnated on different silica-aluminas, obtained by sol-gel. Three different techniques were used to prepare the samples. The catalysts were prepared by incipient wetness...
