Description

Alcohols, C7-9-Branched, C8-Rich is a defined mixture of synthetic, branched-chain primary alcohols where the C8 isomer is the predominant component. This specific composition offers a valuable balance of volatility, solvency, and hydrophobic character, making it a versatile intermediate and performance additive. It is particularly sought after by formulators in the production of plasticizers, surfactants, and synthetic lubricants where consistent quality and predictable performance are critical.

Application

• Plasticizer Alcohol: A key raw material 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 alcohol ethoxylates and other nonionic surfactants for industrial and institutional cleaning formulations.
• Synthetic Lubricant Base Stock: Serves as a precursor for ester-based synthetic lubricants and compressor oils, offering excellent thermal stability and low-temperature performance.
• Solvent & Carrier Fluid: Acts as a medium-volatility solvent in coatings, inks, and agrochemical formulations, and as a carrier in functional fluids.
• Chemical Intermediate: Utilized in various organic synthesis pathways to introduce hydrophobic alkyl chains or to create specialized esters and ethers.
• Additive for Fuels and Functional Fluids: Employed as a component in fuel additives and specialty industrial fluids to modify properties like viscosity and demulsification.
