A process for the selective hydrocarboxylation of propylene to produce predominantly isobutyric acid in the liquid phase is provided. The reaction of propylene, carbon monoxide and water is effected at a temperature of about 10.degree. C. to about 80.degree. C. and at a pressure of about 75 psi to about 1500 psi in the presence of a strong acid and a metal phthalocyanine co-catalyst.

A process for the selective hydrocarboxylation of propylene to produce predominantly isobutyric acid in the liquid phase is provided. The reaction of propylene, carbon monoxide and water is effected at a temperature of about 75.degree. C. to about 150.degree. C. and at a pressure of about 250 psi to about 5000 psi in the presence of a suitable solvent and a catalyst comprising palladium or a palladium compound supported on an inert carrier, an organo-arsine ligand compound and a hydrogen halide.

Selective hydrocarboxylation of propylene to isobutyric acid

A process for the selective hydrocarboxylation of propylene to produce predominantly isobutyric acid in the liquid phase is provided. The reaction of propylene, carbon monoxide and water wherein a water to propylene ratio is maintained of from about 0.01 to a value less than 1.0 is effected at a temperature of about 75.degree. C. to about 150.degree. C. and at a pressure of about 250 psi to about 5000 psi in the presence of a carboxylic acid solvent and a catalyst comprising a coordinating palladium compound, an organo-arsine and a hydrogen halide.

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 oxide compounds and phosphorus or sulfur oxides. These reactions are carried out under relatively mild conditions of temperature and pressure.
