标 题:Reagent and process for the synthesis of oxysulphide-containing fluorine-containing organic derivatives
发明人：FORAT GERARD; MAS JEAN-MANUEL; SAINT-JALMES LAURENT
权利人:RHONE POULENC CHIMIE
摘要:The invention relates to a reagent which is useful for the synthesis of oxysulphide-containing fluorine-containing organic derivatives by reacting with an oxide of sulphur, especially sulphur dioxide, characterized in that it comprises: a) a fluorocarboxylic acid of formula Ew-CF2-COOH where Ew is an electron-withdrawing group or atom which is at least partially salified by an organic or inorganic cation, and b) an aprotic polar solvent; and in that the content of releasable protons carried by its various components, including their impurities, is at most equal to half the initial molar concentration of the said fluorocarboxylic acid. This reagent can be used by heating in order to form fluorine-containing sulphinic or sulphonic acids.

摘要:Disclosed is a process for the synthesis of 1,3,3,3-tetrafluoropropene which comprises, in one embodiment, reacting a compound of CF 3 X 1 with a compound of CX 2 Hâ•?CHX 3 , wherein X 1 , X 2 , and X 3 are each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CF 3 CHâ•?CHX 3 , wherein X 3 is as described above; and when X 3 is not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoropropene. The process in another embodiment comprises preparing tetrafluoropropene comprising thermally cracking one or more compounds capable of producing a reaction mixture which preferably comprises diflurocarbene radicals and vinylidene fluoride, and converting said reaction mixture into—tetrafluoropropene (1,3,3,3-tetrafluoropropene).
