2-Ethyl Hexanol

Brief Overview

2-Ethylhexanol has one primary hydroxyl group. It is a colorless liquid. 2- Ethylhexanol is widely used in the production of dioctyl phthalate (vinyl applications), acrylates, 2-ethylhexyl nitrate, lubrication oil additives, mining chemicals, special plasticizers, herbicides and ester oils (non-vinyl application areas).

Manufacturing process

The industrial production of 2-ethylhexanol is by a three-step process involving the aldol self-condensation of n butyraldehyde followed by dehydration and hydrogenation. The n-butyraldehyde was originally obtained
from acetaldehyde via ethylene but this has been superseded by the oxo process from propylene.

The production of the plasticizer diester bis(2-ethylhexyl) phthalate (DEHP) which is commonly used on the production of PVC is the main application of 2-ethylhexanol. Esters of 2-ethylhexanol often have emollient properties because it is a fatty alcohol. It can also be applied for the production of DOP, DOTP, TOTM

2-ethylhexanol also frequently applied as a low volatility solvent as well. When combined with nitric acid, 2-ethylhexanol can also be used to increase cetane. Additionally, it used to interact with epichlorohydrin and sodium hydroxide to form the molecule's glycidyl ether, which is used as an epoxy reactive diluent in a variety of coatings, adhesives, and sealants applications
