制备了金属有机框架(MOFs)负载的杂多酸催化剂,研究了丙三醇一步氧化酯化的反应条件和催化性能。pH=8,负载8%,反应24 h的条件下,丙三醇转化率48.6%,酯类选择性34.5%。反应过程绿色温和,且催化剂可循环利用,实现了生物柴油副产物的再生。研究了催化过程中各个因素的影响,并讨论了MOFs的传质作用,分析丙三醇一步氧化酯化的反应过程。 The heteropolyacid catalysts supported on metal organic frameworks (MOFs) were prepared and the reaction conditions and catalytic properties of glycerol in one-step oxidation were studied. Under the conditions of pH = 8, load 8% and reaction time 24 h, the conversion rate of glycerol was 48.6% and the ester selectivity was 34.5%. The reaction process is mild green, and the catalyst can be recycled to achieve the regeneration of biodiesel byproduct. The influence of various factors in the catalytic process was studied. The mass transfer of MOFs was discussed, and the reaction of glycerol oxidation in one step was analyzed.
