Chemical Properties

Ebanol is a mixture of isomers. It is a pale yellow liquid with a powerful woody, sandalwood odor withmusk aspect.Thematerial is obtained by aldol condensation of α-campholenaldehyde with 2-butanone. Subsequent isomerization of the double bond with potassium tert-butylate leads to a ??,??-unsaturated ketone, which is reduced with NaBH4 to yield a mixture of chiefly four diastereomeric alcohols. Alternatively, the ??,??-unsaturated ketone can be prepared by dehydration of the ketol, which is obtained when the aldol reaction is performed under special reaction conditions.
It is used in fine fragrances as well as in functional products.
