Double Oxidants Combined Oxidation of Oleic Acid Preparation of Azelaic Acid

摘要

Oleic acid was oxidized to azelaic acid by ozone and hydrogen peroxide as an oxidant jointly in this paper. The effect of major factors, such as the volume and concentration of hydrogen peroxide, the volume and concentration of ozone. The results show that the yield of azelaic acid was up to 71%, when the oxidation was taken under the following condition: oleic acid 20g, phosphotungstic acid hydrate 0.6g, 30% hydrogen peroxide solution 60ml, reaction temperature 70°C, reaction time 8h.
