摘要: 建立了一种碱性条件下过渡金属Co2+和Ni2+共同参与的催化氧化体系,用于高效制备香兰素.该体系能够在0.035 MPa的O2分压下将多种生物质愈创木酚高效快速地转化为香兰素,转化率均约为90%.通过密度泛函理论构筑了反应物的分子模型,并通过对取代基α碳和β碳的电子云密度进行分析,验证了烷基取代基碳的反应能力.同时,考虑到反应过程中存在封闭的CH3OH-O2体系气体环境,进一步对反应条件进行了模拟安全实验,得出该体系90℃发生爆炸的最低氧压力为0.037 MPa,确保了实验的安全进行,也对将来进行工业化生产具有较强的指导意义.

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
