Description

2,2-Bis(Hydroxymethyl)Butyl (9Z,12Z)-Octadeca-9,12-Dienoate is a specialized ester derivative of linoleic acid, a key polyunsaturated fatty acid. This compound is valued for its bifunctional nature, combining the reactivity of primary hydroxyl groups with the hydrophobic character of a long-chain fatty acid ester. It serves as a crucial intermediate and functional additive for industries requiring tailored rheological properties, surface modification, or polymer cross-linking. This product is primarily utilized in the synthesis of advanced polymers, high-performance lubricants, and specialty surfactants.

Application

• Polymer & Resin Synthesis: Acts as a reactive diol monomer or cross-linking agent in the production of polyesters, polyurethanes, and alkyd resins, imparting flexibility and hydrophobicity.
• Lubricant & Grease Formulation: Serves as a synthetic base oil or performance additive to enhance lubricity, thermal stability, and anti-wear properties in industrial and automotive lubricants.
• Surfactant & Emulsifier Production: Used as a key intermediate for synthesizing non-ionic surfactants and emulsifiers for agrochemicals, coatings, and personal care products.
• Coating & Ink Additive: Functions as a plasticizer and viscosity modifier to improve film formation, adhesion, and durability in paints, inks, and protective coatings.
• Chemical Intermediate: Provides a versatile platform for further chemical modifications, including esterification, etherification, and acrylation, to create custom derivatives.
