| Abstract: | The synthesis of azelaic acid by hydrogen peroxide was described.Azelaic acid was synthesized from oleic acid by using WO3/SiO2 as catalyst.In the process of WO3/SiO2 catalytic oxidation to oleic acid,The ef fects of the major factors,such as Si/W,quantity of catalyst,the way of adding H2O2 and its quantity and reaction time were systematically studied.The optimal methodology condition： oleic acid 20g、tert-butyl alcohol 50mL、WO3/SiO2 0.5g、30% H2O2 35g,refluxing for 36h in oxygen condition. |
