Verfahren zur Herstellung von Hexafluorpropan und Perfluorpropan

Perfluoroisobutene-MeOH adduct (2H-octafluoroisobutyl methyl ether) converted to hexafluoropropane by reaction with trialkyl amine (e.g., triethylamine) and H2O. 1,1,1,3,3-Pentafluoropropene also produced in lesser amounts. Electrolysis of reaction product in anhydrous HF (at 10 - 50 C, 0 - 140 kPa,...

Zusammenfassung:Perfluoroisobutene-MeOH adduct (2H-octafluoroisobutyl methyl ether) converted to hexafluoropropane by reaction with trialkyl amine (e.g., triethylamine) and H2O. 1,1,1,3,3-Pentafluoropropene also produced in lesser amounts. Electrolysis of reaction product in anhydrous HF (at 10 - 50 C, 0 - 140 kPa, and 50 - 300 amps/m anode area) yields C3F8 and some CF3CFHCF3 condensed out of gas stream from electrolysis cell.
