Product Description of 2-Ethylhexanol CAS# 104-76-7
2-Ethylhexanol is a branched-chain saturated aliphatic alcohol with molecular formula C₈H₁₈O and molecular weight 130.23. It is a colorless transparent oily liquid with a mild characteristic oily odor. It is slightly soluble in water and miscible with ethanol, ether, ketones and most organic solvents. Its density is about 0.834 g/mL at 20°C, boiling point 183–186°C.
It exhibits typical alcohol chemical reactivity and can participate in esterification reactions. This versatile plasticizer raw material is widely used in fine chemical industries. Store in tightly closed containers in cool, dry and ventilated warehouse, separated from oxidants, heat and open flame sources.

Product Application of 2-Ethylhexanol CAS# 104-76-7
2-Ethylhexanol is mainly used as core raw material to synthesize dioctyl phthalate (DOP) and other plasticizers for PVC resin, which are widely applied in plastic, film and artificial leather industries. It also serves as feedstock for producing surfactants, defoamers, lubricant additives and metal extraction agents. In coating industry, it works as solvent and coalescing agent to improve film-forming performance of paints and varnishes. It can act as wetting agent for textile processing and raw material for synthetic flavors. It is suitable for plastic additive manufacturing, coating formulation, hydrometallurgy extraction and fine chemical synthesis.
