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 bromoacetate Ethyl bromoacetate Ethyl bromoacetate is the chemical compound with the formula CHBrCOCH. It is the ethyl ester of bromoacetic acid and is prepared in two steps from acetic acid. It is a lachrymator and has a fruity, pungent odor. It is also a highly toxic alkylating agent and may be fatal if inhaled. In World War I, ethyl bromoacetate was used as a lachrymatory agent and tear gas agent for chemical warfare under the German code "Weisskreuz" (White Cross), and later as odorant or warning agent in odorless, toxic gases. It is listed by the World Health Organization as a
