Process for the preparation of true acetylene hydrocarbons having a perfluorinated chain

摘要

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 <IMAGE> wherein RF is a straight or branched perfluoroalkyl chain CnF2n+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 RF-C 3BOND CH. The acetylene hydrocarbons are useful for forming compounds having the ability to carry gases such as oxygen for biological purposes.
