WebBoth ethylene and diethyl ether are formed from ethanol dehydration under similar conditions. However, at a lower temperature, symmetrical ether (diethyl ether) is the major product. However, at a relatively higher temperature (180°C), the alkene is recovered as the major product. Ethers can also be prepared by Williamson synthesis.
