Esterification of free fatty acids with methanol using heteropolyacids immobilized on silica
The esterification of palmitic acid with methanol was studied using tungstophosphoric acid (PW), molibdophosphoric acid (PMo) and tungstosilicic acid (SiW) immobilized by sol–gel technique on silica, at 60 º C. It was observed that the catalytic activity decreases in the series: PW-silica > SiW-s...
