Selective Ozidation of Cyclopentene to Cyclopentene Ozide over Compounds containing Molybdenum and Tungsten with dicarbozylic acids as ligands
1.Introduction Recently, investigations on the epoxidation of olefin receive much attention 1-2. Valuable derivatives of cyclopentene, such as glutaraldehyde, 1,2-cyclopentenediol, and glutaric acid 4,5can be produced through the selective oxidation of cyclopentene, which is produced as a by-product in a large quantity in oil refining process, and cyclopentene epoxide is an intermediate product of these derivatives. Compounds containing molybdenum and tungsten with oxalic acid, malonic acid and tartaric acid as ligands were prepared and characterized by Elemental Analysis, FT-IR and TG-DSC to determine chemical compositions and existing forms of the compounds. The as prepared compounds was used to oxidate cyclopentene. When compounds containing tungsten with oxalic acid and malonic acid as ligands were used to oxidate cyclopentene, the yields of main product, cyclopentene oxide, were up to 53.41％ and 80.91％, respectively. The yields of cyclopentene oxide were up to 72.30％, 69.59％ and 16.44％ respectively when compounds containing molybdenum with oxalic acid, malonic acid and tartaric acid as ligands were used as catalysts to oxidate cyclopentene to cyclopentene oxide.
