Abstract: The synthesis of 1,2-propanediol by hydration of propylene oxide, transesterification, hydrogenolysis of glycerol, and reaction of propylene hydrogen with peroxide were introduced and compared. Propylene catalytic oxidation technology has the characteristics of low cost and easy availability of raw materials, integration of two reactions in one reactor, higher yield of 1,2-propanediol, no need to invest in propylene oxide production capacity, and good technical and economic efficiency, which can realize the cleaner production of 1,2-propanediol, and has a good prospect of industrial application. It was suggested that the development of stable and efficient catalytic oxidation catalyst should be the key research direction of this technology in the future.

Key words: propylene, hydrogen peroxide, catalytic oxidation, 1,2-propanediol
