HCID 203165581-(1-Bromo-2,2,2-trifluoroethoxy)-2-chloro-1,1,2-trifluoroethane

Procedure

CF3CH2OCF2CHFCl (104 g.) and bromine (85 g.) were vaporized in a stream of nitrogen at 15-20 l/hr. The gaseous mixture was then passed through a 1 × 12 inch glass tube at 475° C. The crude product (137 g.) was condensed in a "Dry Ice" trap and purified by fractional distillation and preparative gas chromatography. The product CF3CHBrOCF2CHFCl had b.p. 109° C., nD20 1.3525 and analyzed as follows:
