Ethyl sulfate process in which ethylene is reacted with sulfuric acid to produce ethyl sulfate followed by hydrolysis, but this method has been mostly replaced by direct hydration of ethylene. Ethyl sulfate can be produced in a laboratory setting by reacting ethanol with sulfuric acid under a gentle boil, while keeping the reaction below 140 °C. The sulfuric acid must be added dropwise or the reaction must be actively cooled because the reaction itself is highly exothermic. If the temperature exceeds 140 °C, the ethyl sulfate product tends to react with residual ethanol starting material, producing diethyl ether. If the temperature exceeds
Ethyl carbamate Ethyl carbamate Ethyl carbamate (also called urethane) is an organic compound with the formula CHCHOC(O)NH. It is an ester of carbamic acid. It is a white solid. Despite its name, it is not a component of polyurethanes. Because it is a carcinogen, it is little used, but has been detected in alcoholic beverages. It is produced industrially by heating urea and ethyl alcohol. It arise also by the action of ammonia on ethyl chloroformate. Ethyl carbamate has been used as an antineoplastic agent and for other medicinal purposes, but this application ended after it was discovered to be carcinogenic in
