CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID | [Uses]
Trans-2-octenoic acid has found a little use in perfumery
as a trace ingredient in artificial essential
oils, etc.
It has been suggested for use in flavor compositions, but at this time (Oct. 1968) it has
not yet been listed as G.R.A.S. by the American authorities. It could probably be used in
imitation Cheese, Butter, Nut, Butterscotch
compositions, etc. | [Definition]
ChEBI: An olefinic fatty acid that is octanoic acid carrying a double bond at position 2 (the 2E-isomer). | [Production Methods]
Trans-2-octenoic acid can be produced 1) from Hexaldehyde by the Dobner reaction.
2) by regulated hydrogenation of 2-Octynoic
acid. | [Synthesis Reference(s)]
