Oxidation of Hexafluoropropylene with Oxygen to Hexafluoropropylene Oxide

A method for pressure oxidation of hexafluoropropylene (HFP) with oxygen to hexafluoropropylene oxide (HFPO) has been presented. The oxidation wits carried out in a periodically operated reactor. The influence of temperature, the nature of the solvent, and the molar ratio of HFP/O(2) on the course of oxidation was investigated during the preliminary Studies. The magnitudes describing the process were the conversion of the selectivity of transformation to HFPO in relation to HFP consumed, and the yield of HFPO in relation to the initial amount of HFP. The optimisation of the technological parameters of oxidation, temperature., HFP/O(2) molar ratio, and the reaction time was performed by the application of a statistical experimental design method. The function describing the process wits the yield of HFPO.
