Abstract: A large surplus of glycerol is formed as a by-product during the production of biodiesel. The low cost of glycerol has motivated research groups to find new applications of it. This has led to the introduction of a number of selective processes for converting glycerol into commercially valued products. Glycerol oxidation is one of chemical reactions which converts glycerol to more valuable compounds. In this thesis, two heterogeneous catalysts, with TEMPO grafted on mesostructured silica (SBA-16 and KIT-6) were synthesized and characterized by different techniques then followed by performing glycerol oxidation reaction. Glycerol conversion and products selectivity are reported by analyzing the reaction medium via high pressure liquid chromatography (HPLC). The stability and versatility of these catalysts were studied; these materials show real promise as reusable metal-free catalysts for the conversion of a readily available and renewable biofeedstock into highly valued compounds.
