Webproduced synthetically through the direct or indirect hydration of ethylene and as a by-product of certain industrial operations. Several international organizations provide guidance on the application of synthetic ethanol in organic crop and livestock production and the processing of organic foods. Among these organizations, there WebEthanol can be produced using a chemical reaction by starting with the hydrocarbon ethylene. The hydration of ethylene (C2H4 +H2O → C2H5OH) creates ethanol, but some of the ethanol is converted to diethyl ether by a second reaction (2C2H5OH3 → (C2H5)2O+ H2O). The feed to the reactor contains a gas mixture of ethylene and water at 225∘C.
