CITRONELLYL CAPROATE Usage And Synthesis

Chemical Properties

Citronellyl caproate (Citronellyl hexanoate) is a colorless liquid, insoluble in water, soluble in alcohol and perfume oils. Sp.Gr. 0.88. B.P. 240℃. Delicately floral, pronounced fruity (Apple-Pear-Pineapple notes) and somewhat rosy odor of fair tenacity. The taste is not too attractive, since the bitterness of the Citronellol component seems to come through.

Uses

Citronellyl caproate is occasionally used in perfume compositions as a modifier for lower esters of Citronellol, and in certain mild-floral fragrance types, Peony, Freesia, Sweet Pea, etc. It is also interesting in lipstick perfumes where the conventional Ionone-fruitiness certainly needs some renewal in notes.

Preparation

By direct esterification of Citronellol with Caproic acid under azeotropic conditions.

Definition

ChEBI: Citronellyl hexanoate is a carboxylic ester.
