PROCESSES FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE AND/OR 1,2,3,3-TETRAFLUOROPROPENE

A process is disclosed for making CF3CF=CH2 or mixtures thereof with CHF2CF=CHF. This process involves (a) reacting CHCI2CF2CF3, and optionally CHCIFCF2CCIF2, with H2 in the presence of a catalytically effective amount of a hydrogenation catalyst to form CH3CF2CF3 and, when CHCIFCF2CCIF2 is present, CH2FCF2CHF2; (b) dehydrofluorinating CH3CF2CF3, and optionally any CH2FCF2CHF2, from (a) to form a product mixture including CF3CF=CH2 and, if CH2FCF2CHF2 Js present, CHF2CF=CHF; and optionally (c) recovering CF3CF=CH2, or a mixture thereof with CHF2CF=CHF from the product mixture formed in (b) and/or (d) separating at least a portion of any CHF2CF=CHF in the product mixture formed in (b) from the CF3CF=CH2 in the product mixture formed in (b).

METHOD FOR PRODUCTION OF FLUOROALYKYLFLUOROALKANE-SULFONATE

PROBLEM TO BE SOLVED: To provide a method for simply producing, under more moderate condition than heretofore, a fluoroalkylfluoroalkane-sulfonate useful as an intermediate for medicines or agrochemicals and as a reagent for introducing a fluorine-containing group. SOLUTION: The fluoroalkyl fluoroalkane-sulfonate is produced by reacting a perfluoroalkanesulfonyl halide with a fluorine-containing alcohol in the presence of a base. In this case, an organic solvent is not used but water coexists as a solvent. It is particularly preferable that a reaction temperature is ≥-10°C but ≤40°C and water content is ≥0.2 g and ≤5 g per 1 g of the fluorine-containing alcohol. According to this method, for example, 2,2,2-trifluoroethyltrifluoromethane-sulfonate or 2,2,3,3-tetrafluoropropyltrifluoromethane-sulfonate can efficiently be produced, and the discharge amount of waste materials can remarkably be reduced.

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.

(POLYFLUOROALKOXY)-N,N-DIALKYLAMINOFLUOROSULFURANES AND TRIS(POLYFLUOROALKOXY)-N,N-DIALKYLAMINOSULFURANES

(Polyfluoroalkoxy)-N,N-dialkylaminodifluorosulfuranes, bis(polyfluoroalkoxy)-N,N-dialkylaminofluorosulfuranes, and tris(polyfluoroalkoxy)-N,N-dialkylaminosulfuranes were obtained by the reaction of N,N-dialkylaminotrifluorosulfuranes with trimethylsilyloxypolyfluoroalkanes.
