In addition to eugenol, oil of cloves, but not oil of clove stems, contains some aceteugenol, CH3COOC6H3.CgH6.OCH3. This compound can be freed from eugenol by treating it with dilute alkali in the cold and can be prepared readily by boiling eugenol with acetic acid anhydride. The following constants have been found:
