ABSTRACT:
Process for the preparation of true acetylene hydrocarbons with a perfluoro chain, characterized by dehydroiodination with an alkali metal hydroxde in an alcoholic medium of the iodohydrin ##STR1## wherein R.sub.F is a straight or branched perfluoroalkyl chain C.sub.n F.sub.2n+1 -- where n is 1 to 20, and R and R' are identical or different alkyl radicals, followed by distillation, in the presence of solid alkali metal hydroxide, of the resulting acetylenic alcohol obtained to produce a true acetylene hydrocarbon of the formula R.sub.F --C.tbd.CH. The acetylene hydrocarbons are useful for forming compounds having the ability to carry gases such as oxygen for biological purposes.
