Description

Alcohols, C9-11-Branched is a defined mixture of synthetic, branched-chain primary alcohols, primarily comprising isomers of nonanol, decanol, and undecanol. This product is valued for its excellent solvent properties, chemical stability, and versatility as a key intermediate in industrial synthesis. It is essential for manufacturers in the chemical, polymer, and surfactant industries seeking a reliable, high-purity feedstock for producing plasticizers, lubricant additives, and specialty esters.

Application

• Plasticizer Alcohols: A primary feedstock for the synthesis of phthalate and other ester-based plasticizers, imparting flexibility and durability to PVC and other polymers.
• Surfactant & Detergent Intermediate: Used in the production of nonionic surfactants (ethoxylates) and biodegradable detergents for industrial and household cleaning formulations.
• Lubricant Additive Synthesis: Serves as a precursor for ester-based synthetic lubricants and oil additives, offering high thermal stability and low volatility.
• Solvent and Extraction Agent: Functions as an effective solvent for resins, oils, and inks, and as an extraction medium in various chemical processes.
• Chemical Intermediate: A versatile building block for synthesizing acrylates, glycol ethers, and other specialty chemicals used in coatings and adhesives.
• Flavor and Fragrance Industry: Used in the manufacture of esters that serve as aroma compounds and fragrance ingredients.

Quality Control

Our Alcohols, C9-11-Branched is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for composition and purity, to ensure consistency and compliance with industry specifications. Certificates of Analysis (COA) detailing assay, hydroxyl value, color, and moisture content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and maintain product integrity.
