    • Abstract


      Production of benzaldehyde has been carried out by vapour phase oxidation of toluene over silica supported ferric molybdate catalyst, at different support/ catalyst ratio. The temperature, concentration of the catalyst and space-velocities were varied over a wide range with each catalyst. The best results were obtained with ferric molybdate (60%) supported on SiO2 at a temperature of 450°C, space velocity 10373±20 litre hour−1 litre−1, air/toluene ratio 610 and volume of the catalyst 20 cc. The yield of benzaldehyde on the basis of toluene reacted is 70·2% per pass, total conversion 34·9% and conversion to benzaldehyde is 24·5%, surface area and pore size structure of the catalyst was determined by gravimetric method using quartz fibre spring technique.
