Abstract: A catalytic oxidation system involving transition metals Co2+ and Ni2+ was studied for high-efficiency vanillin preparation under alkaline conditions. The catalytic system could efficiently convert a variety of biomass guaiacol into vanillin rapidly in low O2 pressure. Using the density functional theory(DFT), the molecular model of the reactants was constructed and the reaction activity of the substituent group was verified by analyzing the electron cloud density of α-carbon and β-carbon. Furthermore, considering the reaction taken place in a closed environment with the presence of CH3OH and O2 under high temperature and pressure, the safety experiments were employed to ensure the experiment carrying out under safety condition. It also had important guiding significance to industrial production in the future.

Key words: Guaiacol, Vanillin, CH3OH-O2 system, Safety examination
