1-Hexanol is an organic alcohol with a six-carbon chain and a condensed structural formula of CH3(CH2)5OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol. Two additional straight chain isomers of 1-hexanol, 2-hexanol and 3-hexanol, exist, both of which differing by the location of the hydroxyl group. Many isomeric alcohols have the formula C6H13OH. It is used in the perfume industry.
- Al(C2H5)3 + 6C2H4 → Al(C6H13)3
- Al(C6H13)3 + 1½O2 + 3H2O → 3HOC6H13 + Al(OH)3
The process generates a range of oligomers that are separated by distillation.
Another method of preparation entails hydroformylation of 1-pentene followed by hydrogenation of the resulting aldehydes. This method is practiced in industry to produce mixtures of isomeric C6-alcohols, which are precursors to plasticizers.
This method is instructive and useful in laboratory synthesis but of no practical relevance because of the commercial availability of inexpensive 1-hexanol from ethylene.
Occurrence in Nature
Cis-3-Hexenal, another volatile organic carbon biomolecule, is also considered responsible for the freshly mowed grass flavor.
