Only 5% of the ethene is converted into ethanol at each pass through the reactor. By removing the ethanol from the equilibrium mixture and recycling the ethene, ...

This process is carried out under high pressure (about 60-70 atmospheres) and high temperature (about 300°C). A phosphoric acid catalyst is also used to speed ...

22 окт. 2024 г. · Hydration of ethene · Temperature of around 300ºC · Pressure of 60 – 70 atm · Concentrated phosphoric acid catalyst.

Ethene molecules react with sulphuric acid generating an alcohol, that is ethanol. This conversion of ethene molecule to ethanol molecule involves three steps.

The mechanism of hydration of ethene to form ethanol involves three steps. Step 1: Protonation of ethene to form carbocation by electrophilic attack of H3O+:.
