Low-Temperature Preparation of Fluoroalkanes from a Mixture of Carbon-Tetrachloride, Dichloromethane and Anhydrous Hydrogen-Fluoride Casing a Fluorinated Gamma-Alumina Supported Iron(II,III)/Cobalt(II,III) Oxide Catalyst
1,1,1,2-tetrafluoroethane has been prepared at 473 K under static conditions, from a feedstock of carbon tetrachloride, dichloromethane and anhydrous hydrogen fluoride using a gamma-alumina supported fluorinated Co(II, III)(85)Fe(II, III)(15)O-x, catalyst. Conversion to hydrofluoroalkanes was ca. 58% efficiency as quantified by liquid phase F-19 NMR analysis.
