| 摘 要： | 1IntroductionIn recent years,there are many papers published ontoluene oxidation to benzaldehyde.The most i mpor-tant research works of these papers are electric oxida-tion and toluene oxidizied by using air in gas phase orin liquid phase.A novel technology for benzaldehydeproduction is developed,with which manganese sul-fate reacts with ammonium carbonate to yield manga-nese carbonate and ammoniun sulfate.Manganese car-bonate is baked for being changed into manganese ses-quioxide,which can ox…

| Abstract: | Effects of reaction parameter on yield of benzaldehyde produced from toluene oxidization using hydrogen peroxide in subcritical
water are investigated. The experimental results show that if the molar ratio of hydrogen peroxide to toluene is controlled
within a reasonable range, the by-products may be neglected. The optimum technology of toluene oxidization to benzaldehyde
is reaction time 60 min,reaction temperature 350 °C, molar ratio of hydrogen peroxide to toluene 3.5. The yield of benzaldehyde
can reach 17.2% under the optimum condition. Research results of chemical reaction kinetics show that the consecutive reaction
consists of two first-order reaction, and activation energy of these two reactions are 89 kj·mol−1 and 76 kJ·mor−1 respectively.
