Combustion of Alcohol

  1. As the hydrocarbon, alcohols undergo combustion with the presence of oxygen to produce carbon dioxide and water.
  2. Combustion of alcohol producesless soot compare to combustion of alkanes and alkenes due to the present of oxygen in the –OH group.
  3. Owing to the presence of the –OH group, the percentage of carbon in alcohol is relatively low when compare with the percentages of carbon of alkanes and alkenes.
Equation:
Combustion of Ethanol
C2H5OH + 3O2 → 2CO2 + 3H2O

Combustion of Propanol
C3H7OH + 9/2 O2 → 3CO2 + 4H2O
