ESTERIFICATION OF FREE FATTY ACIDS WITH METHANOL TO BIODIESEL USING HETEROGENEOUS ACID CATALYSTS
The esterification of palmitic acid with methanol was studied using poly(vinyl alcohol) crosslinked with sulfosuccinic acid (SSA) and polystyrene crosslinked with di-vinylbenzene with sulfonic acid groups, as catalysts, at 60ºC. It was observed that the PVA matrixes with sulfonic acid groups were mo...
