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 carbamate for studies to determine the effects on Japanese cancer rates to be performed but apparently none were ever done. Prior to World War II, ethyl carbamate saw relatively heavy use in the treatment of multiple myeloma before it was found to be toxic, carcinogenic, and largely ineffective. By US FDA regulations, ethyl carbamate has been withdrawn from pharmaceutical use. However, small quantities of ethyl carbamate are also used in laboratories as an anesthetic for animals. Ethyl carbamate was reclassified as a Group 2A carcinogen by IARC in 2007. Ethyl carbamate is frequently used as an anaesthetic in animal experiments, with
