Isooctanoic acid, with the chemical name2-ethylhexanoic acid, is a colorless transparent liquid at room temperature with a special aromatic odor. It is slightly soluble in cold water but readily soluble in most organic solvents. As a high value-added fine chemical, isooctanoic acid readily reacts with metals to form metal salt compounds, which are used in industrial applications as additives such as driers and stabilizers. In addition, the ester compounds of isooctanoic acid, owing to their excellent lubricating properties, are also used as plasticizers for PVC, nitrocellulose, chlorinated rubber and polypropylene.

On September 17, 2023, the Jiangxi Provincial Petroleum and Chemical Industry Association organized experts in Nanchang to hold the scientific and technological achievement appraisal meeting for the "Research on Clean and Efficient Synthesis of Sterically Hindered Acids" project undertaken by Jiangxi Silinco Co., Ltd. According to tests by SGS, an internationally renowned third-party institution, the purity of isononanoic acid and isooctanoic acid is greater than 99.68% and 99.92% respectively. Users reported good results, and the market prospects are broad. The expert group unanimously concluded that the process technology of this achievement has reached the internationally leading level.
