Efficient Conversion of Oils to Biodiesel Catalyzed by Uncalcined Disodium Metasilicate Granules
An efficient, simple conversion of oils to biodiesel catalyzed by uncalcined disodium metasilicate granules (0.3 mm-1 mm) is reported. Under optimum reaction conditions of catalyst content of 9 wt.%; methanol to oil molar ratio of 9:1; reaction temperature of 65 ºC with a constant stirring of 200 rp...
