Synthetic method for heptafluoropropyl trifluoromethyl ether

The invention relates to a synthetic method for heptafluoropropyl trifluoromethyl ether. The synthetic method comprises the following steps: with trifluoromethyl hypofluoride and perfluoropropylene asraw materials, subjecting gaseous trifluoromethyl hypofluoride and liquid perfluoropropylene to generate a free-radical addition reaction at a low temperature so as to generate the heptafluoropropyltrifluoromethyl ether. The invention provides a chemical method to synthesize perfluoroalkyl ether. The method provided by the invention has the following advantages: the use of highly-active fluorinegas or an expensive catalyst is not needed; a previously-produced mixture of trifluoromethyl hypofluoride and fluorophosgene can be utilized for polar synthesis; production steps are simplified; meanwhile, the perfluoroalkyl ether has the advantages of high yield, simple synthetic method, and a certain industrial popularization value.

Technology for the preparation of perfluoro-organic compounds

Fluorination by elemental fluorine of fluorine-containing alkenes, alkanes, ethers and tertiary amines was investigated, aimed at obtaining the perfluorinated analogs. The factors affecting yield of the target compounds were studied. Elements of technology were elucidated.

Perfluorination of Allene Derivatives by Direct Fluorination

Perfluoropropane was prepared from allene with elemental fluorine in the presence of sodium fluoride in 84percent yield for the first time.The reaction of allene with elemental fluorine afforded 2,2-difluoropropane in the absence of sodium fluoride.Methoxyallene and cyanoallene were perfluorinated with elemental fluorine in the presence of sodium fluoride to give heptafluoropropyl trifluoromethyl ether and heptafluoropropyl cyanide in good yields respectively.In addition, the direct fluorination of cyanoallene in the presence of cesium fluoride afforded N,N-difluorononafluorobutylamine in 95percent yield.
