SELECTIVE HYDROCARBOXYLATION OF PROPYLENE TO ISOBUTYRIC ACID

摘要

(5218) THE 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 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 soluble palladium salt, an organo-arsine and a hydrogen halide.
