ABSTRACT:
The present process is suitable for preparing carboxylic acids wherein greater than 50 mole percent of the carboxylate groups are at the terminal position which comprises bringing together in a reaction zone an olefin or mixture of olefins wherein greater than 50 mole percent of the olefin has unsaturation at other than the terminal position, water and carbon monoxide in the presence of a cobalt catalyst and a pyridine-type promoter, preferably pyridine, in a mole ratio of promoter to catalyst between about 5:1 and 15:1, at pressures from about 70 kilograms per square centimeter to about 300 kilograms per square centimeter, at temperatures between about 180.degree. C. and about 220.degree. C.
