4-Octanol is a chemical compound from the group of alcohols , more precisely the chiral alcohols. So there are two enantiomers : ( R ) -4-octanol and ( S ) -4-octanol. When “4-octanol” is mentioned in this article or in other scientific literature without a prefix, the 1: 1 mixture (racemate) of ( R ) -4-octanol and ( S ) -4-octanol is meant.
Extraction and presentation
4-Octanol can be obtained by asymmetric addition of a metal alkyl with an aldehyde . It can also be obtained by hydroboration of cis -4-octene . Also by a Grignard reaction of butyl magnesium bromide with butanal .
properties
4-Octanol is a colorless liquid that is sparingly soluble in water.
