2-Ethylhexanol Usage And Synthesis
  • Chemical Propertiescolourless liquid
  • Chemical Properties2-Ethyl-1-hexanol has a mild, oily, sweet, slightly floral odor reminiscent of rose and sweet, fatty-floral taste with a fruity note
  • Chemical Properties2-Ethylhexanol is a clear, colorless liquid.
  • OccurrenceReported found in papaya, peach, pear, blackberry, strawberry, cabbage, Parmesan and mozzarella cheese, butter, roasted chicken, cognac, sherry, grape wines, tea, avocado, kiwifruit, crab and clam.
  • Uses2-Ethylhexanol is the most important C8 alcohol and is used mainly in manufacturing plasticizers. Other minor uses include the manufacturing of 2-ethylhexyl acrylate, as a dispersing agent and wetting agent, as a solvent for gums and resins, as a cosolvent for nitrocellulose, and in ceramics, paper coatings, rubber latex, textiles, and fragrances.
  • Uses2-Ethyl-1-hexanol is used as a flavor, fragrance and plasticizer. It is used to prepare diesters bis(2-ethylhexyl) phthalate. It reacts with nitric acid and used as an octane booster. Its ester, 2-ethylhexyl ester is a component of sunscreen octocrylene. Further, it is used as a low volatility solvent for resins, animal fats, waxes, vegetable oils and petroleum derivatives. In addition to this, it is used in plasticizer, dioctyl phthalate, which is used in the production of polyvinyl chloride products.
  • General DescriptionA dark brown liquid with an aromatic odor. Insoluble in water and less dense than water. Flash point between 140 - 175°F. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity Profile2-Ethylhexanol is an alcohol. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. 2-Ethylhexanol is incompatible with strong oxidizing agents and strong acids.
  • Health HazardAnesthesia, nausea, headache, dizziness; mildly irritating to skin and eyes.
  • Fire Hazard2-Ethylhexanol is combustible.
  • Chemical ReactivityReactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
  • Safety ProfileModerately toxic by ingestion, skin contact, intraperitoneal, subcutaneous, and parented routes. An experimental teratogen. Other experimental reproductive effects. A severe eye and moderate skin irritant. Mutation data reported. A dangerous fire hazard when ex posed to heat or flame; can react vigorously with oxidzing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also ALCOHOLS.
  • Chemical SynthesisBy hydrogenation of aldehydes obtained by the oxo process; also synthesized from propylene; by catalytic reduction of 2-ethyl-2-hexenal and other similar patented processes.
  • CarcinogenicityMale and female F344 rats were dosed by oral gavage with 0, 50, 150, or 500 mg/kg 2-ethylhexanol (0.005% in aqueous Cremophor EL, a polyoxyl 35 castor oil), 5 days/week for 2 years. There were no differences of biological importance between the vehicle control and a water control group that was included in the study. There was no evidence of treatment-related neoplastic lesions in any of the exposed groups.
