Denaturants for ethyl alcohol

摘要

This patent discloses a new class of denaturants for commercial ethyl alcohol, particularly for use in mixtures such as Gasohol. These denaturants are the lower alcoholic esters of monocyclic naphthenic acids and are particularly useful because they can be added in very low concentrations and still provide a noxious flavor and odor to the alcoholic system to make it non-potable.
