Isooctyl Alcohol, identified by CAS number 26952-21-6, is a primary alcohol characterized by its branched eight-carbon chain. It is typically a clear, colorless liquid with a faint, pleasant odor. Its molecular formula, C8H18O, and molecular weight of approximately 130.23 g/mol, provide insights into its chemical behavior. The compound exhibits a boiling point around 183-186°C and a melting point of -76°C, and it has limited solubility in water (about 1 g/L at 20°C), but is miscible with most organic solvents.

The synthesis of Isooctyl Alcohol commonly involves the oxo process, also known as hydroformylation, where olefins are reacted with synthesis gas (carbon monoxide and hydrogen) in the presence of a catalyst. For isooctyl alcohol, this typically involves branched C7 olefins. The resulting aldehyde is then hydrogenated to form the alcohol. Understanding the production process and the various manufacturers of isooctyl alcohol is crucial for ensuring a stable supply chain and competitive pricing for businesses worldwide. The quality of isooctyl alcohol can vary slightly depending on the isomer distribution from different production routes.

The market demand for Isooctyl Alcohol is robust, driven by its extensive use as a precursor in the production of plasticizers. Dioctyl phthalate (DOP) and other phthalate esters, historically derived from isooctyl alcohol, are widely used to impart flexibility to PVC and other polymers. While regulatory shifts are influencing the plasticizer market, isooctyl alcohol remains a key component in many industrial formulations. The price of isooctyl alcohol is influenced by crude oil prices, the cost of olefin feedstocks, and global manufacturing capacity.

Beyond plasticizers, Isooctyl Alcohol serves as an intermediate for nonionic surfactants, which are essential in detergents, emulsifiers, and wetting agents. These surfactants are valued for their effectiveness in a wide range of temperatures and pH conditions. The chemical industry relies on Isooctyl Alcohol for producing these crucial agents that enhance product performance across consumer and industrial applications. Sourcing isooctyl alcohol with the required purity for these synthesis processes is a key consideration for manufacturers.

Other significant applications include its use as a solvent in coatings, inks, and adhesives, where its solvency power and evaporation rate are beneficial. It also functions as a defoamer in various systems, including latex paints and industrial processes. The demand for isooctyl alcohol is projected to remain steady, supported by its broad utility and the ongoing need for its derivatives in industries such as textiles, paper, and oilfield chemicals. Companies looking to buy isooctyl alcohol should research its availability and pricing from reputable suppliers.

In summary, Isooctyl Alcohol (CAS 26952-21-6) is a versatile chemical with a well-established presence in the industrial landscape. Its chemical properties, synthesis pathways, and diverse applications, particularly in plasticizers and surfactants, underscore its importance. Understanding the market dynamics, including price trends and supplier reliability, is essential for businesses that depend on this critical chemical intermediate. Manufacturers and suppliers of isooctyl alcohol continue to innovate, ensuring its continued relevance.
