2-Ethylhexanol

2-Ethylhexanol

2-Ethylhexanol (abbreviated 2-EH) is a fatty alcohol, an organic compound primarily used for the production of plasticizers. It is a colorless liquid that is poorly soluble in water but soluble in most organic solvents.

Production

2-Ethylhexanol is produced through a three-step process: the aldol condensation of propionaldehyde, followed by hydrogenation and distillation. The process results in a mixture of compounds, from which 2-EH is separated.

Uses

The primary use of 2-ethylhexanol is in the production of dioctyl phthalate (DOP), a plasticizer. It is also used as a low volatility solvent. Other applications include the production of lubricants, coatings, and adhesives.

Health Effects

Exposure to 2-ethylhexanol can cause irritation to the eyes, skin, and respiratory tract. It may also cause dizziness, headache, and in severe cases, unconsciousness. Long-term exposure can lead to liver and kidney damage.

Environmental Impact

2-Ethylhexanol is not readily biodegradable and can accumulate in the environment. It is toxic to aquatic life and can cause long-term adverse effects in the aquatic environment.
