  • Catalyst for the production of light alpha olefins by oligomerization of ethylene
    Patent number: 5496783
    Abstract: Process for oligomerizing ethylene into light alpha olefins, mainly 1-butene, 1-hexene, 1-octene and 1-decene, in which the ethylene is contacted with a catalyst obtained by mixing a zirconium compound with an organic compound chosen from within the class of acetals and ketals and with a chlorine or bromine-containing compound of aluminium hydrocarbyl.
    Type: Grant
    Filed: June 2, 1994
    Date of Patent: March 5, 1996
    Assignee: Institut Francais du Petrole
    Inventors: Yves Chauvin, Dominique Commereuc, Francois Hugues, Helene Olivier, Lucien Saussine

  • Non-aqueous liquid composition with an ionic character and its use as a solvent
    Patent number: 5104840
    Abstract: A non-aqueous liquid composition with an ionic character resulting from the contacting of at least one alkylaluminum dihalide with at least one quaternary ammonium halide and/or at least one quaternary phosphonium halide, said composition being liquid below 80.degree. C., for example, between -70.degree. and +40.degree. C., is useful as a solvent of catalysts for the dimerization, codimerization and oligomerization of olefins.
    Type: Grant
    Filed: March 20, 1991
    Date of Patent: April 14, 1992
    Assignee: Institut Francais du Petrole

  • Process for producing organolanthanides, the resultant compounds and their use
    Patent number: 4845201
    Abstract: A process for producing organolanthanides by reaction of a rare-earth metal with an unsaturated compound in an ether medium, the resultant compounds and the use of these compounds in organic synthesis and for catalysis is disclosed. The process is conducted at -80.degree. to +100.degree. C., in the absence of oxygen and any compound having active protons. The resultant compounds are useful as catalysts, e.g., in the hydrogenation of olefins and diolefins and in the polymerization thereof, and are useful as chemical intermediates.
