Claims19
A process for producing a fluorinated alcohol, comprising:
- (a) reacting an hydrofluorocarbon with an oxidizing agent and fluorine to produce said fluorinated alcohol.
A vapor phase process for producing 2,2,2-trifluoroethanol, comprising reacting 1,1,1-trifluoroethane with fluorine and air in a fluidized bed reactor, wherein a molar ratio of fluorine to 1,1,1-trifluoroethane is from 0.1 to 0.5, a molar ratio of air to 1,1,1-trifluoroethane is from 2.0 to 10.0, a temperature in said fluidized bed reactor ranges from 175.degree. C. to 225.degree. C., a residence time ranges from 30 to 60 seconds, to produce said 2,2,2-trifluoroethanol.
