3-Hexanol is a chemical compound from the group of secondary alcohols . It is one of the 17 structural isomers of hexanols . The compound occurs in two stereoisomeric forms. Whenever “3-hexanol” is mentioned in the scientific literature or in this article without any further addition, one always means the racemate , i.e. ( RS ) - (±) -3-hexanol, a 1: 1 mixture of ( R ) - and ( S ) -3-hexanol.
Occurrence
3-Hexanol occurs naturally in some plants such as saffron and lavender, as well as in the fruits of various plants such as bananas and melons.
Extraction and presentation
Racemic 3-hexanol can be obtained by hydroboration of 3-hexene or 3-hexyne .
safety instructions
The compound forms highly flammable vapor-air mixtures. It has a flash point of 41 ° C. The explosion range is between 1.1% by volume (45 g / m 3 ) as the lower explosion limit (LEL) and 7% by volume (298 g / m 3 ) as the upper explosion limit (UEL). The ignition temperature is 305 ° C. It therefore falls into temperature class T2.
