Ethyl acetate ethanol to acetaldehyde, which leaves the wine with a sharp vinegar-like taste. In the field of entomology, ethyl acetate is an effective asphyxiant for use in insect collecting and study. In a killing jar charged with ethyl acetate, the vapors will kill the collected insect quickly without destroying it. Because it is not hygroscopic, ethyl acetate also keeps the insect soft enough to allow proper mounting suitable for a collection. Ethyl acetate can be hydrolyzed in acidic or basic conditions to regain acetic acid and ethanol. The use of an acid catalyst accelerates the hydrolysis, which is subject to the
Ethyl macadamiate Ethyl macadamiate Ethyl macadamiate is the ester of ethyl alcohol and the fatty acids derived from "Macadamia terifolia" seed oil (q.v.). Ethyl macadamiate is commonly used in cosmetic formulations. Ethyl macadamiate is the ethyl ester of the free fatty acids produced by the complete saponification of macadamia oil. The primary constituents of ethyl macadamiate are ethyl oleate and ethyl palmitoleate. Ethyl macadamiate is a clear, colorless liquid at room temperature, with a typical fatty ester odor. Ethyl macadamiate's melting (congealing) point is and its specific gravity is 0.88. Ethyl macadamiate spreads very aggressively, and has a light, nongreasy dry skinfeel
