Oxidation of toluene to benzoic acid in acidic medium
Oxidation of toluene to benzoic acid in basic and neutral medium
On industrial scale, alcoholic potassium permanganate is preferred to acidic or alkaline potassium permanganate because in the presence of alcohol both the reactants KMnO4 and C6H5CH3 are mixed very well and form homogeneous solution and in homogeneous medium reaction takes place faster than in heterogeneous medium. Further more in neutral medium OH- ions are produced in the reaction itself.

Explanation:
Alcoholic potassium permanganate (KMnO4) is used as an oxidant in the manufacture of benzoic acid from toluene because it provides a suitable medium for the reaction to occur efficiently. This is due to the following observations:
1. Homogeneous Medium: Alcoholic KMnO4 forms a homogeneous medium with the reactants. In a homogeneous medium, all the reactants and the oxidant are present in the same phase, which allows for easier and faster reaction kinetics. This is because the oxidant molecules can easily come in contact with the reactant molecules, leading to a higher rate of reaction.
2. Faster Reaction: The reaction between toluene and KMnO4 in alcoholic medium is faster compared to acidic or alkaline conditions. This is because the alcoholic medium enhances the reactivity of both the oxidant and the reactant. The presence of alcohol molecules facilitates the breaking of bonds in the reactant molecules and promotes the transfer of electrons during the oxidation process.
3. Oxidation Potential: Alcoholic KMnO4 has a higher oxidation potential compared to alkaline or acidic KMnO4. This means that it is a stronger oxidizing agent and is more effective in oxidizing the reactant (toluene) to form the desired product (benzoic acid). The higher oxidation potential of alcoholic KMnO4 is attributed to the presence of alcohol molecules, which can act as electron donors and enhance the reactivity of the oxidant.
Redox Equation:
The balanced redox equation for the reaction between toluene and alcoholic KMnO4 can be written as follows:
C6H5CH3 + 2KMnO4 + 3H2O → C6H5COOH + 2MnO2 + 2KOH + 4H2O
In this equation, toluene (C6H5CH3) is oxidized to benzoic acid (C6H5COOH) by the alcoholic KMnO4. The MnO4- ions in KMnO4 are reduced to MnO2, and water (H2O) is used as a solvent and a source of protons (H+) in the reaction.
Overall, the use of alcoholic KMnO4 as an oxidant in the manufacture of benzoic acid from toluene offers several advantages, including a homogeneous reaction medium, faster reaction kinetics, and a higher oxidation potential. These factors contribute to the efficiency and effectiveness of the oxidation process.
