PRODUCTION OF 1,1-DICHLORO-1-FLUOROETHANE AND 1-CHLORO-1,1-DIFLUOROETHANE

PURPOSE:1,1,1-Trichloroethane is fluorinated by hydrogen fluoride in a liquid phase to obtain 1,1-dichloro-1-fluoroethane and 1-chloro-1,1-difluoroethane in high selectivity. CONSTITUTION:The reaction is carried out at 1.0-10.1kg/cm pressure and at 10-70 deg.C reaction temperature by using a catalys...

Zusammenfassung:	PURPOSE:1,1,1-Trichloroethane is fluorinated by hydrogen fluoride in a liquid phase to obtain 1,1-dichloro-1-fluoroethane and 1-chloro-1,1-difluoroethane in high selectivity. CONSTITUTION:The reaction is carried out at 1.0-10.1kg/cm pressure and at 10-70 deg.C reaction temperature by using a catalyst comprising an antimony compound and a tin compound at 0.0001-0.05 tin/antimony atomic ratio.
