Ethylhexyl compounds

2-ethylhexyl compounds
2-ethylhexanol
2-ethylhexylamine
2-ethylhexanal
2-ethylhexanoic acid
2-ethylhexyl acrylate

Under Ethylhexylverbindungen it summarizes a group of chemicals that the common structural element 2-ethylhexyl own. Occasionally the group is called the isooctyl group rather unspecifically .

Whenever the term "2-ethylhexyl compound" is used without a prefix in this article or in the scientific literature , a residue is always meant that is derived from the racemate .

Technical manufacturing

The central step of the synthesis is the aldol condensation of two molecules of butanal (as a C _{4 building} block) by reaction of the α-carbon atom of one molecule with the aldehyde group of the other molecule. It leads to this branched carbon structure with 8 carbon atoms.

The starting material for the production is initially propene . The propene is first reacted with carbon monoxide and hydrogen in a hydroformylation reaction to form butanal (butyraldehyde). This is followed by the aldol condensation of two molecules of butyraldehyde to form 2-ethyl-3-hydroxyhexanal .

After elimination of water and catalytic hydrogenation , 2-ethylhexanol is obtained.
