Catalytic Transformation of Triglycerides to Biodiesel with SiO 2 -SO 3 H and Quaternary Ammonium Salts in Toluene or DMSO

SiO -SO H, with a surface area of 115 m ·g , pore volumes of 0.38 cm ·g and 1.32 mmol H /g, was used as a transesterification catalyst. Triglycerides of waste cooking oil reacted with methanol in refluxing toluene to yield mixtures of diglycerides, monoglycerides and fatty acid methyl esters (FAMEs)...
