Process for making hexafluoropropane and perfluoropropane.

摘要

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<0> - 50<0>C, 0 - 140 kPa, and 50 - 300 amps/m<2> anode area) yields C3F8 and some CF3CFHCF3 condensed out of gas stream from electrolysis cell.
