Ethyl acetate Fischer equilibrium mentioned above. In the laboratory, and usually for illustrative purposes only, ethyl esters are typically hydrolyzed in a two-step process starting with a stoichiometric amount of a strong base, such as sodium hydroxide. This reaction gives ethanol and sodium acetate, which is unreactive toward ethanol: The rate constant is 0.111 L/mol·s at 25 °C. The for rats is 5620 mg/kg, indicating low toxicity. Given that the chemical is naturally present in many organisms, there is little risk of toxicity. Overexposure to ethyl acetate may cause irritation of the eyes, nose, and throat. Severe overexposure may cause weakness, drowsiness,
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
