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 cyanoacetate Ethyl cyanoacetate Ethyl cyanoacetate is an organic compound that contains a carboxylate ester and a nitrile. It is a colourless liquid with a pleasant odor. This material is useful as a starting material for synthesis due to its variety of functional groups and chemical reactivity. Ethyl cyanoacetate may be prepared in various ways: Ethyl cyanoacetate is a colorless liquid, it boils at atmospheric pressure at 209 °C. The vapor pressure follows the Antoine equation log(P) = A−(B/(T+C)) (P in bar, T in K) with A = 7.46724, B = 3693.663 and C = 16.138 in the temperature range from 341
