Description

Didecyl Carbonate CAS NO 6290-55-7 is a high-purity, synthetic organic carbonate ester, specifically the diester of carbonic acid and decyl alcohol. This compound serves as a versatile intermediate and functional additive, prized for its lipophilic character and chemical stability. It is primarily utilized by manufacturers in the production of advanced lubricants, plasticizers, and specialty polymers, where it contributes to performance and processing characteristics.

Application

• Lubricant & Grease Formulation: Acts as a synthetic base oil or performance additive, offering excellent thermal stability and low-temperature fluidity for industrial and automotive applications.
• Polymer & Plasticizer Intermediate: Serves as a key monomer or co-monomer in the synthesis of polycarbonates and other specialty polymers, and as a precursor for high-molecular-weight plasticizers.
• Personal Care & Cosmetics: Used as an emollient and solvent in high-end cosmetic formulations, providing a non-greasy feel and enhancing product spreadability.
• Chemical Synthesis: Functions as a stable alkylating agent or protecting group reagent in organic synthesis for pharmaceuticals and agrochemicals.
• Functional Fluids: Employed as a component in heat transfer fluids, hydraulic fluids, and dielectric fluids due to its electrical properties and compatibility with various materials.
• Surface Coatings: Incorporated into coatings and inks as a coalescing agent or plasticizer to improve film formation, flexibility, and adhesion.
