    摘要: Norbornadiene and an acrylic acid ester, e.g. methyl acrylate, are catalytically codimerized in the presence of a three-component homogeneous catalytic system consisting of nickel acetylacetonate, an alkyl aluminum chloride and triphenylphosphine. The resulting codimer can be used as a precursor for missile fuel. The ester portion of the acrylic acid ester is the radical RCH.sub.2 O- wherein the R is an H or an alkyl containing up to 10 carbon atoms.

    摘要: Norbornadiene and isoprene are catalytically codimerized to an olefinic codimer. Used is a three-component homogeneous catalytic system consisting of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride. The codimer upon hydrogenation forms .beta.-methyltetramethylene nortricyclane having utility as a diluent for a high energy hydrocarbon missile fuel.

    摘要: The removal of color bodies from an olefinic or saturated endo-endo hexacyclic homodimer of norbornadiene or mixtures thereof is accomplished by the use of a serpentine clay. Also acid bentonite clay or a montmorillonite clay can be used to remove the color bodies from the saturated dimer. The saturated dimer has a high density and a high heat of combustion making it useful as a missile fuel. Removal of the color bodies avoids possible catalyst poisoning in the hydrogenation of the olefinic to the saturated dimer. Also removal of the color bodies from the saturated dimer eliminates the possible problem of a material precipitating out on engine turbine blades and causing maintenance or operational problems.
