A process for the preparation of p-toluic acid by liquid phase oxidation of p-xylene in water |
| abstract |
The present invention provides a process for the preparation of p-toluic acid by liquid phase oxidation of p-xylene using oxygen or air as oxidant in the presence of p-toluic acid, water as solvent and cobalt salt or its combinations with salts of Ce, Mn as catalyst. Oxidation is carried out at 130-190°C and pressure sufficient to keep water in liquid state. Oxidation step is followed by filteration to obtain p-toluic acid as major product. Unreacted p-xylene is recovered and recycled and the catalyst is recovered from aqueous phase and is recycled. |
