【摘要】：以竹加工业副产物竹粉为原料,利用磷酸活化-微波炭化法制备新型炭基固体磺酸催化剂.设计正交试验考察竹粉与磷酸固液比、磷酸浓度、微波功率与微波时间对所制备的炭基固体磺酸样品中的磺酸量的影响.结果表明:新型炭基磺酸催化剂适宜的制备条件为:固液比为1∶6,磷酸质量分数为40%,浸渍时间12 h,微波功率为800 W,微波时间为20 min.催化剂在合成环己酮乙二醇缩酮的反应中表现出优良的催化活性和重复使用性.与传统的炭化方法相比,磷酸活化-微波炭化法具有加热快、效率高、能耗低、生产周期短等优点.
[Abstract]:A new carbon-based solid sulfonic acid catalyst was prepared by phosphoric acid-microwave carbonization from bamboo powder, a by-product of bamboo processing industry. The effects of the ratio of bamboo powder to phosphoric acid, the concentration of phosphoric acid, microwave power and microwave time on the amount of sulfonic acid in the carbon based solid sulfonic acid samples were studied by orthogonal experiment. The results showed that the optimum preparation conditions were as follows: the ratio of solid to liquid was 1: 6, the mass fraction of phosphoric acid was 40%, the impregnation time was 12 h, the microwave power was 800 W, and the microwave time was 20 min. The catalyst showed excellent catalytic activity and reusability in the synthesis of cyclohexanone glycol Ketal. Compared with the traditional carbonization method, phosphoric acid-microwave carbonization has the advantages of fast heating, high efficiency, low energy consumption and short production cycle.
