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 butylacetylaminopropionate a derivative of beta-alanine. The EPA has classified ethyl butylacetylaminopropionate as a biochemical substance (biopesticide) based on the fact that it is "functionally identical" to beta alanine. Ethyl butylacetylaminopropionate Ethyl butylacetylaminopropionate (trade name IR3535) is an insect repellent. As ethyl butylacetylaminopropionate is solely a repellent, it has no killing action and does not give rise to selection pressure or development of resistance. It is a colorless and almost odorless oil and is intended to be applied to the skin of humans and animals. It has a broad efficacy against various insects like mosquitoes, ticks, lice, and other bugs. Ethyl butylacetylaminopropionate
