Description

Ricinoleic Acid Dimer CAS NO 79415-97-7 is a high-purity, dimerized derivative of ricinoleic acid, a key fatty acid derived from castor oil. This specialty chemical is valued for its unique bifunctional structure, offering enhanced thermal stability and reactivity compared to its monomeric counterpart. It serves as a critical intermediate and performance additive for manufacturers in the polymer, lubricant, and specialty chemical industries seeking to improve product durability and functionality.

Application

• Polymer & Resin Modification: Acts as a reactive monomer or plasticizer in the synthesis of polyamides, polyesters, and alkyd resins, improving flexibility and impact resistance.
• High-Performance Lubricants & Greases: Used as a base stock or additive to formulate synthetic lubricants with excellent viscosity-temperature characteristics and oxidation stability.
• Corrosion Inhibitors: Employed in the formulation of protective coatings and metalworking fluids due to its film-forming and surface-active properties.
• Adhesives & Sealants: Functions as a tackifier and modifier to enhance adhesion, cohesion, and low-temperature performance in various adhesive systems.
• Surfactants & Emulsifiers: Serves as a hydrophobic building block for synthesizing non-ionic and anionic surfactants for industrial and cosmetic applications.
• Chemical Intermediate: A versatile precursor for further chemical reactions, including hydrogenation, epoxidation, and amidation, to produce a range of derivatives.

Quality Control

Our Ricinoleic Acid Dimer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards suitable for industrial and specialty applications. A comprehensive Certificate of Analysis (COA) detailing key parameters such as dimer content, acid value, hydroxyl value, and color is provided with every shipment to guarantee supply reliability and product integrity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is easily oxidized; for long-term storage, consider blanketing with an inert gas such as nitrogen. Keep away from strong acids and organic solvents. Keep container tightly sealed when not in use to minimize moisture pickup and oxidation.
