Effects of HCl and HNO3 on the oxidation of toluene to benzaldehyde by H2O2 over TS-1 modified with Al in aqueous phase

摘要

This research studies effects of HCl and HNO3 in aqueous solution on the oxidation reaction between tolueneand hydrogen peroxide to benzaldehyde over titanium silicalite-1 catalyst modified with Al. The reaction wascarried out at reaction temperature 120°C in a pressurized autoclave reactor. The research found that theaddition of HCl and HNO3 not only increases the concentration of toluene in the aqueous phase but alsoincreases the formation of benzaldehyde as main product in the reaction.
