TRANS-2-OCTENOIC ACID Chemical Properties,Usage,Production
Chemical Properties
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.
Production Methods
Trans-2-octenoic acid can be produced 1) from Hexaldehyde by the Dobner reaction. 2) by regulated hydrogenation of 2-Octynoic acid.
Definition
ChEBI: An olefinic fatty acid that is octanoic acid carrying a double bond at position 2 (the 2E-isomer).
