  • Carbonylation of olefinically unsaturated compounds
    Patent number: 4344866
    Abstract: Oxygenated organic compounds, e.g. esters, aldehydes, and amides, are prepared by reacting an olefinically unsaturated compound with carbon monoxide and a compound containing a replaceable hydrogen atom in the presence of a catalyst comprising cobalt or ruthenium carbonyl and a promoter ligand. The promoter ligand is selected from the group consisting of heterocyclic nitrogen compounds and phosphorus or sulfur oxides. These reactions are carried out under relatively mild conditions of temperature and pressure.

  • Process for the separation of catalyst from products obtained in the hydrocarboxylation of unsaturated nitriles
    Patent number: 4312781
    Abstract: A process is provided which includes the separation of a hydrocarboxylation-type catalyst together with the hydrocarboxylation solvent from a reaction mixture containing an oxygenated cyanocompound product, the hydrocarboxylation catalyst and the hydrocarboxylation solvent by contacting the reaction mixture with a hydrocarbon to form a hydrocarbon/solvent conjugate phase, and separating the resulting hydrocarbon phase from the solvent phase.
