Hydration ethene
WebThis step is the slowest step in the mechanism of dehydration of an alcohol. Hence, the formation of the carbocation is considered as the rate-determining step. 3. Alkene formation: This is the last step in the dehydration of alcohol. Here the proton generated is eliminated with the help of a base. WebConsider the following gas-phase reaction to produce ethanol from ethylene: . Take the initial number of moles of ethylene to equal 1. The initial number of moles of water is determined by the selected steam-to-ethylene molar ratio. Initially, there is no ethanol in the reaction vessel.
