2-Ethylhexanol (2-EH) is a clear, colorless liquid with a faint, sweet and slightly fruity odor. It is a primary alcohol with an aliphatic chain of nine carbon atoms and an average molecular weight of 130.23. 2-EH is also known as octanol and 2-ethylhexyl alcohol and is primarily used in the manufacture of plasticizers and as a solvent for paints, coatings, and inks.
2-EH is produced by the catalytic hydrogenation of 2-ethylhexanal, which is derived from the reaction of propylene and formaldehyde. It is a highly flammable liquid and can be affected by light, heat, and air.
2-EH is used as a plasticizer in many applications including coatings, adhesives, and sealants. It is also used as a solvent in many paint formulations and inks. In addition, 2-EH is used as a raw material in the production of 2-ethylhexyl acrylate, which is used as a monomer in the manufacture of acrylic-based polymers.
2-EH is also used as a feedstock in the manufacture of detergents, surfactants, and lubricating oils. In the textile industry, it is used as a softener and a spinning aid. 2-EH is also used in the production of cosmetics, fragrances, and as a flavor enhancer for food and beverages.
2-Ethylhexanol is a hydrophobic compound and is only slightly soluble in water. It is miscible with many common organic solvents such as ethanol and acetone. 2-EH has a low vapor pressure, low volatility, and low flash point, making it suitable for many industrial applications.
