摘要： The present invention relates to a method for preparing hexafluoropropylene oxide with high yield, and particularly to a method for preparing hexafluoropropylene oxide comprising the step of performing a two-phase interfacial reaction between an organic phase containing hexafluoropropylene and an aqueous phase containing a hypochlorite oxidant in the presence of a phase-transfer catalyst and a non-ionic surfactant to improve the degree of emulsification and dispersion of the organic phase and to increase the contact interfacial area, thereby increasing the efficiency and the yield of the reaction.

摘要： The present invention relates to a process for preparing fluoroacrylic acid ester using a pervaporation composite membrane, in particular, to a process for preparing fluoroacrylic acid ester performed in such a manner that water and unreacted fluoroalcohol generated in esterification between fluoroalcohol and (meth)acrylic acid in the presence of an acid catalyst are condensed and then passed through a pervaporation membrane to effectively remove water, followed by recycling the unreacted fluoroalcohol removed of water. The present process exhibits much higher conversion rate of fluoroacrylic acid ester, allows the decrease of energy consumption and could be performed in environment-friendly manner.
