n-Octanol Manufacturer: Applications of n-Octanol

发布时间：2025-09-09 08:31

Physicochemical properties of n-octanol: a colorless liquid with a strong, aromatic odor. Density: 0.83; refractive index: 1.430; melting point: −16°C; boiling point: 196°C. It is immiscible with water but miscible with ethanol, diethyl ether, and chloroform. Production method: It is obtained as a by‑product in the manufacture of lauric acid from palm kernel oil. Alternatively, it can be produced via catalytic controlled polymerization of ethylene, followed by hydrolysis and separation. Applications: A key raw material for the production of high‑performance plasticizers; a principal feedstock for synthesizing the UV absorber UV‑531; also used as a precursor for fragrances, octanal, caprylic acid, and their esters, as well as a solvent, antifoaming agent, and lubricant additive.
