  Method of Hydrodechlorination to Produce Dihydrofluorinated Olefins

  摘要：

  本文揭示了一种制备含氟烯烃的过程，包括在存在催化剂的情况下，将氯氟烯烃与氢气接触，以使氯取代物被氢取代的温度足够高。还揭示了一种用于氯氟烯烃的氢脱氯催化剂组合物，其中铜金属沉积在一种载体上。

  Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkene with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkene with hydrogen to produce a fluorine-containing olefin, wherein said catalyst is a composition comprising chromium, nickel and optionally an alkali metal selected from potassium and cesium. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkenes comprising copper, nickel, and an alkali metal selected from potassium and cesium, and methods of making such catalysts.

  The present invention relates to azeotropic or azeotrope-like compositions comprising a fluorinated olefin having the formula E- or Z-C 3 F 7 CH═CHC 3 F 7 , and at least one alcohol, halocarbon, hydrofluorocarbon, fluoroether, or alkanes and combinations thereof. In one embodiment, the one compound selected from the group consisting of alcohols, halocarbons, fluoroalkyl ethers, hydrofluorocarbons, alkanes is either methanol, ethanol, iso-propanol, n-propanol, trans-1,2-dichloroethylene, cis-1,2-dichloroethylene, n-propyl bromide, C 4 F 9 OCH 3 , C 4 F 9 OC 2 H 5 , HFC-43-10mee, HFC-365mfc, heptane, or combinations thereof. In another embodiment, these compositions are useful in cleaning applications as a degreasing agent or defluxing agent for removing oils and/or other residues from a surface.
