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 Corporation In 2004, Ethyl Corporation became a subsidiary of NewMarket Corporation (). Tetraethyllead has been recognized as a contributor to soil, air and water lead pollution, and is toxic to humans. While leaded gasoline made engines more efficient, lead pollution has increased by over 625 times previous levels in the past century due partly to pollution by leaded fuel. Ethyl Corporation historically denied that tetraethyllead poses significant public health risks in excess of those associated with gasoline itself. Tetraethyllead was supplied for blending with raw gasoline in the form of "Ethyl Fluid", which blended tetraethyllead with the lead scavengers 1,2-dibromoethane and
