Preparing Acyclic Haloalkyl Group Containing Compound Patents (Class 570/191)
  • Patent number: 4329525
    Abstract: A compound is chlorinated with chlorine to produce chlorinated product and hydrogen chloride byproduct. Recovered hydrogen chloride byproduct is contacted with oxygen and a molten salt mixture containing the higher and lower valent chlorides of a multivalent metal, such as cuprous and cupric chloride, to effect recovery of the hydrogen chloride by enriching the molten salt content of the higher valent chloride. The molten salt, enriched in higher valent chloride, is then dechlorinated by use of a stripping gas, preferably hydrogen chloride, to produce a gaseous effluent containing stripped chlorine and the stripping gas, which is then recycled to the chlorination step. The presence of stripping gas, as a diluent, improves the chlorination operation.

  • Patent number: 4319061
    Abstract: Terminally-functional saturated hydrocarbon low molecular weight liquid polymers are prepared by cationic polymerization of a 1-alkene containing at least one tertiary or phenyl substituted carbon in the presence of a transfer agent containing a benzylic or tertiary halogen and at least one primary or secondary halogen wherein the 1-alkene is capable of being polymerized by a Friedel Crafts catalyst.
