A method for pressure oxidation of hexafluoropropylene (HFP) to hexafluoropropylene oxide (HFPO), using oxygen, is presented. Oxidation was achieved in a batch-fed reactor at temperature range between 130 to 170°C. The influence of temperature and kind of solvents, such as 1,2,2-trichloro-1,1,2-trifluoroethane (CFC-113) and carbon tetrachloride on the yield of HFPO and the course of oxidation was investigated in preliminary studies. The maximum HFPO yield of approximately 83% was noticed.

W artykule zostały przedstawione podstawowe metody epoksydacji heksafluoropropylenu do epoksyzwiązku w zależności od zastosowanego czynnika utleniającego. Omówiono także sposób i warunki prowadzenia procesu utleniania heksafluoropropylenu. Zbadano wpływ czterech rozpuszczalników na proces utleniania heksafluoropropylenu do tlenku heksafluoropropylenu, gdzie parametrami stałymi była temperatura, stosunek molowy heksafluoropropylenu do tlenu oraz trzykrotne dozowanie tlenu.

In this article the methods of the epoxidation of hexafluoropropylene to epoxy compound depending on used oxidizer were presented. The methods and conditions of conducting of the oxidation of the hexafluoropropylene were also discussed. The influence on the oxidation of the hexafluoropropylene of four solvents was investigated, where constant parameters were temperature, molar ratio of hexafluoropropylene to oxygen and threefold dosage of oxygen.

W artykule omówiono właściwości związków perfluoroorganicznych bazujących na tlenku heksafluoropropylenu (THFP), ich możliwe zastosowanie oraz metody otrzymywania tlenku perfluoropropylenu z heksafluoropropylenu (HFP) w zależności od czynnika utleniającego. Przedstawiono także bardzo istotne problemy związane z kontrolą pomiarową prowadzoną w trakcie procesu utleniania HFP do THFP. Opisano także nową metodę utleniania HFP do THFP, której próby podjęto w Instytucie Technologii Chemicznej Organicznej Politechniki Szczecińskiej.

This paper present properties of perfluoroorganic compounds based on hexafluoropropylene oxide (HFPO), their application and describes methods of the synthesis of hexafluoropropylene oxide (HFPO) from hexafluoropropylene (HFP) depends on oxidizing agents. It were presented also, very significant problems, which are connected with measurement monitoring conducted during the oxidation process of HFP to HFPO. It was presented also, the new oxidation method from HFP to HFPO, which was performed in Institute of Organic Chemical Technology at Szczecin University of Technology.

The results of the oxidation of hexafluoropropylene (HFP) to hexafluoropropylene oxide (HFPO) have been presented. The oxidation was carried out in an autoclave within the range of temperatures of 120 - 170°C and in the presence of an organic solvent (carbon tetrachloride). Molecular oxygen was used here as an oxidizing agent. The influence of: the molar ratio of HFP/O from 13.4 to 4.09:1, the process temperature, the addition of inert gas (nitrogen) from 4 to 18 atm and the periodical dosing of oxygen were investigated. The functions describing the process were: the conversion of HFP and the yield of HFPO in relation to HFP consumed. The presented process is very interesting owing to a wide application of HFPO.

The results of the oxidation of hexafluoropropylene (HFP) to hexafluoropropylene oxide (HFPO) using hydrogen peroxide were presented. The oxidation was carried out in the glass reactor at temperatures below -35°C and in the presence of phase transfer catalyst. The influence of: the molar ratio hydrogen peroxide/ HFP, concentration of HFP in methylene chloride and the molar ratio methanol/HFP was investigated.
