Opis:: 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.

oligomers of hexafluoropropylene oxide
Opis:: Oligomers of hexafluoropropylene oxide are raw materials for the synthesis of compounds having unique properties such as high chemical and thermal resistance. Two basic parameters have influence on the process of hexafluoropropylene oxide oligomerization: the kind of the catalyst and the solvent. The temperature and pressure influence this process to a lesser extent. The influence of halide ions, the solvent and the temperature on the oligomerization of hexafluoropropylene oxide has been studied.

Opis:: 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.

Opis:: Oligomers of hexafluoropropylene oxide were tested as potential materials for obtaining various compounds with unique properties, of which most important are chemical and thermal resistance. Two basic parameters influence the oligomerization process of hexafluoropropylene oxide: the type of the catalyst and the type of the solvent. Other parameters such as temperature and pressure have significantly less influence. The influence of tertiary amines as catalyst, the type of the solvent, temperature, pressure and catalyst concentration were tested in the process of hexafluoropropylene oxide oligomerization.
