Ethanol is prepared by hydration of ethene.
The molecular formula of ethene is C2H4. An addition of a water molecule will make ethene into ethanol (C2H5OH). Addition of water to a molecule and its assimilation into the molecular formula is known as hydration. Ethene obtained from cracking of petroleum along with water is pressurized to 60 atmosphere and passed over heated (300°C) phosphoric acid (H3PO4). Ethanol is directly produced in this reaction. The double bonded ethene molecule breaks its pi bond to accommodate one H and one OH group. The phosphoric acid is a catalyst.
