The stoichiometric ratio of reactants needed to produce a stable explosive compound, such as Ammonium Nitrate Fuel Oil (ANFO), can vary depending on the desired explosive strength. However, the commonly used ratio for ANFO is 94% ammonium nitrate (NH4NO3) and 6% fuel oil (such as diesel).
To calculate the stoichiometric ratio, we need to determine the molar ratios of the reactants involved in the balanced chemical equation for the explosive reaction. The balanced equation for the reaction of ammonium nitrate (NH4NO3) and fuel oil can be written as:
6NH4NO3 + C12H23 = 2N2 + 12H2O + CO2 + 5O2
From the balanced equation, we can see that for every 6 moles of ammonium nitrate (NH4NO3), we need 1 mole of fuel oil (C12H23) to produce the desired explosive reaction.
