本文用回流吸附法制备了活性炭负载的含磷杂多酸催化剂(HPA/C),并测定了其担载量及其在反应过程中的变化。这种催化剂对乙酸酯化反应活性高,且HPA不易流失,可反复使用,并将其与HPA的催化活性作了比较。
In this paper, activated carbon-loaded heteropolyacid catalyst (HPA / C) was prepared by reflux adsorption method. The supported amount and reaction time of HPA / C were determined. This catalyst has high reactivity to acetylation and HPA is not easily lost. It can be reused and compared with the catalytic activity of HPA.
