Copper (I) and silver carbonyl catalysts were prepared in strong acids such as sulfuric acid, hydrogen fluoride, boron trifluoride-hydrate and fluoro sulfuric acid. Carbonylation of olefins, alcohols, dienes, diols, aldehydes and saturated hydrocarbons were carried out under atmospheric pressure and at room temperature by using copper (I) carbonyl catalyst, and tert-carboxylic acids were prepared in high yield.The highly hindered carboxylic acid was prepared from isobutylene oligomer. The industrial process of highly hindered carboxylic acid was established by using sulfuric acid-phosphoric acid-water mixed solvent in the recycle use of catalyst, and pilot plant started in 1988. This carbonylation method is available to the production of another compound also.The derivatives of highly hindered carboxylic acid is stable to hydrolysis and heat. The usages of this hindered carboxylic acid are paint, microgel, surfactant, stabilizer, initiator of polymerization, agricultural chemicals.

The development of highly branched carboxylic acids and their production.
