trifluoro-(trifluoromethyldisulfanyl)methane

Conditions: temp:40.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4,040 g of bis-(trifluoromethyl) -disulfane and 2,000 g of 96% strength sulfuric acid were initially placed in a 10 l Hasteloy autoclave and were charged at 18° C. with a pressure of 5 bar of nitrogen. 1,000 ml of liquid chlorine were pumped into this solution at 40° C. in the course of 2 hours. The reaction mixture was stirred for a further 12 hours at 40° C. and under a pressure of 14 to 16 bar, and it was then purified by distillation. 4,250 g of trifluoromethanesulfenyl chloride having a boiling point of 0° C. at normal pressure and 350 g of unreacted bis-(trifluoromethyl) -disulfane were obtained. were charged at 18° C. with a pressure of 5 bar of nitrogen were pumped into this solution at 40° C. in the course of 2 hours was then purified by distillation
