    1-Octano CAS 111-87-5

    1-Octanol is a straight-chain fatty alcohol characterized by an eight-carbon saturated chain and a terminal primary hydroxyl group. This colorless, oily liquid, commonly identified as capryl alcohol or n-octyl alcohol, functions as a powerful surface-tension reducer and surfactant intermediate, a reaction mechanism that enables it to act as an effective defoaming agent in industrial aqueous systems by disrupting stable foam membranes. Primarily utilized in the production of ester-based plasticizers and synthetic lubricants, this C8 alcohol serves as a critical industrial supply for the synthesis of octyl phthalates and various specialty esters used in the polymer industry. Its amphiphilic nature also makes it an essential standard in pharmaceutical and environmental sciences for determining the octanol-water partition coefficient , which predicts the lipophilicity and bioaccumulation of chemical substances. We provide competitive factory pricing for high-purity volumes to meet customized specifications, ensuring reliable bulk supply supported by complete technical documentation including MSDS, TDS, COA.

    Applications

    • Chemical Synthesis: Serves as a primary raw material for manufacturing phthalate plasticizers (DOP replacement) and octyl esters.
    • Defoaming Agent: Widely used in the paper, textile, and oil drilling industries to control foam in large-scale aqueous processing.
    • Lubricants & Greases: Employed in the production of synthetic fatty acid esters for high-performance industrial lubricants.
    • Fragrance & Flavor: Acts as a base intermediate for various fruity and floral esters in the perfume and food additive sectors.

    Storage & Safety

    • Storage: Store in a cool, well-ventilated area away from heat, sparks, and open flames. 1-Octanol is stable under normal conditions but should be kept in tightly closed containers made of carbon steel or stainless steel to prevent contamination and evaporation.
    • Safety & PPE: This substance is classified as causing skin and serious eye irritation. Industrial operators must wear chemical safety goggles, protective coveralls, and nitrile or neoprene gloves. In confined spaces, use local exhaust ventilation or an organic vapor respirator. Ensure eye wash stations are readily accessible in the handling area.

    Quality Assurance

    Our quality control process focuses on the strict elimination of branched isomers and moisture. Every batch of 1-Octanol is analyzed via Gas Chromatography (GC) to ensure the straight-chain purity exceeds 99% and Karl Fischer Titration for precise water content measurement. This ensures the material remains chemically stable during esterification and provides predictable partition coefficients in technical research applications.

    FAQ - Technical & Supply Chain

    • Q:

      Is this 1-Octanol (CAS 111-87-5) suitable for use as a defoamer in industrial fermentation?

      A: Yes, n-octanol is commonly intended for use as a defoaming agent in industrial fermentation and wastewater treatment. Its low solubility in water combined with its ability to rapidly spread across the air-water interface allows it to collapse foam quickly without interfering with the biological processes of the fermentation media at standard dosage levels.
    • Q:

      How does the purity of your 1-Octanol affect the production of synthetic esters?

      A: High-purity 1-Octanol (≥99%) is critical for the synthesis of specialty esters like octyl acetate or octyl phthalate. Residual moisture or lower-chain alcohols can cause side reactions during acid-catalyzed esterification, leading to unwanted byproducts, odors, or a drop in the plasticizing efficiency of the final polymer additive.
