Uses
Isooctanoic Acid, is an important fine chemical product. The sodium naphthenate drying agent is a high-tech product, is widely applied to the fields of coatings, printing ink, agriculture, automobiles, plastics, rubber, petrochemical industry, papermaking, cosmetics, aerospace, military and the like, is mostly used for producing metal salt of isooctanoic acid, is widely applied to the coating industry because the salt has a more obvious drying effect than naphthenate, and meets the requirements of people on high-grade light-colored coatings. Isooctanoic acid is mainly used as a salifying reagent for synthesizing penicillin sodium salt by a solvent method in the aspect of medicine. In addition, the glycerol ester is used in cosmetics, perfumes and the like, and is an excellent plasticizer.
Manufacturing Process
The isooctanoic acid industrial synthesis mainly has two routes, one is isooctanol oxidation method, although the method has high selectivity, reliable raw material source and simple operation, the process flow is long, and the large-scale production is not easy; secondly, n-butyl aldehyde is used as a raw material, 2-ethyl hexenal is generated through condensation and dehydration, isooctyl aldehyde is obtained through hydrogenation, and isooctyl acid is obtained through oxidation.
