Synthesis method of 3,4-hexanedione
A synthesis method of 3,4-hexanedione comprises a step of 4-hydroxy-3-hexanonen oxidation, and in the step of 4-hydroxy-3-hexanonen oxidation, water is used as a catalyst, acetic acid is used as a cocatalyst, and ozone is used as an oxidizing agent to carry out an oxidation reaction on 4-hydroxy-3-hexanonen, and after the reaction, distillation under reduced pressure is carried out to obtain the 3,4-hexanedione. According to the synthesis method of 3,4-hexanedione in the invention, in the process of 4-hydroxy-3-hexanone oxidation, the 4-hydroxy-3-hexanone is placed in the water, the ozone is used for oxidation on the 4-hydroxy-3-hexanone, and the acetic acid is used as the cocatalyst, so that the entire oxidation reaction process is mild in conditions and simple to operate, no sewage is produced when the final product (3,4-hexanedione) is obtained, and the yield is greatly increased.
