2 -nonanol is a naturally occurring chemical compound from the substance group of aliphatic alcohols. Next the two enantiomers (R )-2- nonanol, and ( S)-2 -nonanol, there are other structural isomers, such as 1- nonanol, 3- nonanol, 4 -nonanol, and.

Occurrence

Nonane -2 -ol is found in various vegetable oils, for eg in the oil of ginger (Zingiber officinale), and in the secretions of a number of insects. The alcohol is a pheromone of the honey bee.

Properties

From 2 -nonanol are two stereoisomers. However, has practical significance only the racemate. This has a melting point of -35 ° C. The boiling point at atmospheric pressure is 198 ° C. The vapor pressure function is given by Antoine corresponding log10 (P) = A- ( B / ( T C)) (P in Pa, T in ° C) with A = 10.179, B = 1961.437 and C = 189.330 in the temperature range of 253 to 353 K. the critical temperature is 377 ° C, the critical pressure of 25.3 bar, and the critical volume of 0.575 l · mol -1.

The vapors of the liquid readily flammable (flash-point 82 ° C) with air when the substance is heated above its flash point form explosive mixtures.

Use

Nonane -2-ol is - as well as the isomeric nonane -3-ol and nonane -4-ol -, used as a constituent of perfumes and as a flavoring agent in foods, such as baked goods.
