Dehydration of Alcohol


  1. When alcohol is heated, it will decompose to form alkene and water. 
  2. For example, heating ethanol will produce ethene, heating propanol will produce propene, and so on. 
  3. This process is called dehydration of alcohol.



Dehydration of Ethanol 
    C2H5OH → C2H4 + H2O 
Dehydration of Propanol
    C3H7OH → C3H6 + H2O

    Dehydration of Alcohols Using Aluminium Oxide as Catalyst

    Dehydration of alcohols using an acid catalyst


    Catalyst:
    Sulphuric acid or Phosphoric acid

    Temperature: 170°C
