Paragraph 0055; 0056, (2016/11/28)
The present invention discloses a method for synthesis of hexafluoropropylene oxide by use of a two-liquid-phase buffer solution method under atmospheric pressure, and belongs to the technical field of fluorine chemical industry, and the method is as follows: under atmospheric pressure, sodium hypochlorite is used as an oxidant, a buffer system is used for assisting reaction, C12-C18 alkyl trimethyl ammonium bromide is used as a catalyst, and the two-liquid-phase method is used for synthesis of hexafluoropropylene oxide, the specific steps of the two-liquid-phase method are as follows: under atmospheric pressure, the buffer system is dissolved in an aqueous sodium hypochlorite solution, and then the C12-C18 alkyl trimethyl ammonium bromide and toluene are added into the aqueous sodium hypochlorite solution to form a mixture. The method is mild in reaction conditions, safe and reliable in production, low in power consumption, simple in process, low in production cost, better in environmental protection property, and high in economic efficiency.
A process for the preparation of hexafluoropropylene oxide

Paragraph 0028-0029, (2017/03/18)
The invention discloses a preparation method for hexafluoropropylene oxide. Hexafluoropropylene is used for preparing hexafluoropropylene oxide through a molecular oxygen liquid-phase oxidation method. A hexafluoropropylene solvent used in the molecular oxygen liquid-phase oxidation method is mixture of perfluoropolyethers and fluorocarbon, and a metallic oxide catalyst is added in a reaction process of the molecular oxygen liquid-phase oxidation method. The preparation method has the advantages that the metallic oxide catalyst is added so that temperature required by a reaction is reduced, solubility of hexafluoropropylene in the solvent is greatly increased, and reaction selectivity is improved.
