Reaction Steps
CF3CH2OCF2CF2H (110 g.) was reacted with bromine (125 g.) by passing a mixture of the two diluted with a stream of nitrogen through a 12 × 1 inch glass tube heated to 475° C. The effluent product was condensed in a "Dry Ice" trap and purified by fractional distillation and preparative gas chromatography to give CF3CHBrOCF2CF2H., b.p. 80° C., nD25 1.3155. This product analyzed as follows:
