以太西煤基活性炭和聚苯胺为原料制备了煤基碳基固体酸,并采用SEM、XRD和TG对催化剂进行了表征。研究了催化剂对环己酮甘油缩酮反应的催化活性,通过单因素实验得到最佳工艺条件:环己酮与甘油物质的量比为1∶1.2,催化剂质量为反应物质量的0.5%,带水剂用量为10 m L。在该条件下环己酮甘油缩酮收率达到96.5%,选择性达98.0%以上,催化剂重复使用5次后收率仍可达88.6%,说明该煤基碳基固体酸具有良好的催化活性和重复使用性。 Coal-based carbon-based solid acids were prepared from the coal-based coal-based activated carbon and polyaniline. The catalysts were characterized by SEM, XRD and TG. The catalytic activity of the catalyst on the reaction of cyclohexanone and glycerol was studied. The optimum conditions were obtained by single factor experiments: the mass ratio of cyclohexanone to glycerol was 1: 1.2, the mass of catalyst was 0.5% of the reactant, Aqueous dosage of 10 m L. Under these conditions, the yield of cyclohexanone glycerol ketal reaches 96.5%, the selectivity reaches 98.0%, and the yield of the catalyst can reach 88.6% after repeated use for 5 times, indicating that the coal-based carbon-based solid acid has good catalytic activity And reusability.
