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 cyanoacrylate and produce heat during polymerization. After curing, the resulting resin softens at temperatures above . The service temperature of the joint is . Its dielectric constant at 1 megahertz is 3.33. In the U.S., the Threshold Limit Value for ECA is 0.2 ppm. Heating causes depolymerization of the cured poly-ECA, producing gaseous products which are a strong irritant to the lungs and eyes. Ethyl cyanoacrylate Ethyl cyanoacrylate (ECA), a cyanoacrylate ester, is an ethyl ester of 2-cyano-2-propenoic acid. It is a colorless liquid with low viscosity and a faint sweet smell in pure form. It is the main component of
