  • Patent number: 4599432
    Abstract: A process for preparing a composition containing an alkenyl succinic anhydride, which comprises subjecting an olefin and maleic anhydride to a thermal addition reaction, followed by addition of a peroxide to cause unreacted olefin and maleic anhydride to undergo a radical initiated reaction.
    Type: Grant
    Filed: November 7, 1984
    Date of Patent: July 8, 1986
    Assignee: Mitsubishi Chemical Industries Ltd.
    Inventors: Katsuhiko Kuroda, Hideki Yamanouchi
  • Patent number: 4368286
    Abstract: A thermoplastic resin composition is quickly crystallizable and comprises 0.1 to 10 wt. parts of an alkali metal salt of higher fatty acid having carbon atoms of at least 26 obtained by an addition of a fatty acid to .alpha.-olefin having carbon atoms of at least 23 per 100 wt. parts of a thermoplastic polyester.
    Type: Grant
    Filed: March 18, 1981
    Date of Patent: January 11, 1983

  • Patent number: 4322314
    Abstract: A cobalt component is separated from a hydroesterification reaction mixture obtained by reacting a polyhydric alcohol with an olefin and carbon monoxide in the presence of a cobalt carbonyl complex and a pyridine base, by contacting (a) pyridine or .gamma.-picoline and (b) water with said reaction mixture containing the cobalt component and the product of a fatty acid ester of the polyhydric alcohol to separate it into two phases consisting of a phase containing the fatty acid ester of polyhydric alcohol and a phase containing a cobalt component.In the process, the weight ratio of pyridine or .gamma.-picoline to the product ester is 0.5 to 5 and the weight ratio of water to pyridine or .gamma.-picoline is 0.05 to 10.
