Uses and applications

What the substance is used for, by industry and function

USE A sensitive method for the extraction and determination of polycyclic aromatic hydrocarbons (PAHs) using alcoholic-assisted dispersive liquid-liquid microextraction (AA-DLLME) and HPLC was developed... The effective parameters (type and volume of extraction and dispersive solvents, amount of salt and stirring time) on the extraction recovery were studied and optimized utilizing factorial design (FD) and central composite design (CCD). The best recovery was achieved by FD using 2-ethyl-1-hexanol as the extraction solvent and methanol as the dispersive solvent...

The optimized conditions were 145 uL of 2-ethyl-1-hexanol as the extraction solvent and 4.2% w/v of salt (NaCl) in sample solution...

2-Ethylhexanol is mainly used as the alcohol component for the manufacture of ester plasticizers for soft poly(vinyl chloride) (PVC).

Mercerizing textiles, as solvent for dyes, resins, oils, also claimed to possess antifoaming properties.

Plasticizer for PVC resins, wetting agent, organic synthesis, solvent mixtures for nitrocellulose, paints, lacquers, baking finishes ... Inks, rubber, paper, lubricants, photography, dry cleaning.

Industrial uses: Processing aids not otherwise specified, Monomers, Surfactant (surface active agent), Fuel agents, Fuel, Solvent, Dispersing agent.

How it is made

2-Ethyl hexanol is produced in 4 steps: (1) aldolization of butyraldehyde and subsequent dehydration, (2) separation of aldolization solution, (3) hydrogenation of unsaturated 2-ethyl-2-hexenal as an intermediate product, (4) fractionation of 2-ethylhexanol. The butyraldehyde required for the aldolization stage is made by hydroformylation of propene.

(A) Oxo process, from propylene and synthesis gas. (B) Aldolization of acetaldehyde or butyraldehyde, followed by hydrogenation. (C) From fermentation alcohol.
