Versuchsvorschrift

A mixture of 400 g of 1,2-dichloro-1-iodotrifluoroethane, 140 g of tetrafluoroethene and 4 g of benzoyl peroxide was heated in 1 L autoclave at 130° C. for 4.5 hours. GC analysis of the reaction mixture (458 g) indicated 37% of starting material, 51% of desired product and 7% of 5,6-dichloro-1-iodoperfluorohexane. The reaction mixture was distilled on a 91 cm spinning band column to give 18.6 g of lower boiler, bp 80°-99° C. (mainly starting material), 138.6 g of starting material, bp 100°-102° C., 50.1 g of mixture of starting material and desired product, bp 103°-140° C. and 211 g of pure desired product, bp 140°-142° C.
