Abstract
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.
