DI-N-HEXYL FUMARATE Usage And Synthesis

Aroma

DI-N-hexyl fumarate has found use in perfumery for its effect which resembles that of the Tiglic and Angelic esters of Amyl- and Hexyl alcohols. It has warm, herbaceous-winey, slightly green and quite tenacious odor of versatile use in perfumesy.

Physical properties

Colorless liquid. Sp.Gr. 1.01. B.P. 278° C. Almost insoluble in water, soluble in alcohol and oils.

Uses

Not confined to the Chamomile type of herbaceous notes, DI-N-hexyl fumarate can supply fixation of the herbaceous notes in Lavender, Geranium, Lavandin, Rosemary, Clary sage, etc. and it blends well into Fougeres, Chypres, Oriental types, etc.
DI-N-hexyl fumarate has the advantage of being much less expensive than the TigIic and Angelic esters, and since Fumaric acid is commercially available in high grade of purity, it also offers an ester free from isomers (until recently, Tiglic acid was not available at reasonable cost unless accompanied by a considerable amount of Angelic acid).

Production Methods

DI-N-hexyl fumarate can be produced by direct esterification of n-Hexanol with Fumaric acid under azeotropic conditions.
