2-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. When “2-hexanol” is mentioned in the scientific literature or in this article without any further addition, one always means the racemate , i.e. ( RS ) - (±) -2-hexanol, a 1: 1 mixture of ( R ) - and ( S ) -2-hexanol.

Extraction and presentation

Racemic 2-hexanol can be obtained in the laboratory by reacting 1-hexene with water and sulfuric acid.

properties

2-Hexanol is a colorless liquid that boils at 140 ° C under normal pressure . According to Antoine, the vapor pressure function results from log ₁₀ (P) = A− (B / (T + C)) (P in Torr, T in ° C) with A = 8.4, B = 2076 and C = 237 in the temperature range from 25 to 142 ° C. The compound forms highly flammable vapor-air mixtures. It has a flash point of 45 ° 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).
