NaF含量对以水滑石结构为前驱体的固体碱催化剂F-Ca-Mg-Al及碳酸二甲酯合成的影响OA北大核心CSTPCD
The effect of NaF amount on solid base catalysts derived from F-Ca-Mg-Al layered double hydroxides and dimethyl carbonate synthesis
以碳酸丙烯(PC)和甲醇为原料,经酯交换反应合成的多功能、环保的碳酸二甲酯(DMC)是一种绿色、节能的合成方法.CaO固体碱催化剂对该反应具有良好的催化性能,但其再生性不理想.以F-Ca-Mg-Al水滑石(LDHs)为原料,制备了一系列不同NaF用量的固体碱催化剂,并对其进行了表征和酯交换反应测试.与不加氟的FCMA-0催化剂相比,经氟改性后的催化剂的比表面积、碱量、催化活性等性能均有明显提高.催化活性由高到低依次为:FCMA-0.8>FC…查看全部>>
Versatile and environmentally benign dimethyl carbonate (DMC) synthesized by propylene carbonate (PC) and methanol via transesterification is green and energy efficient. A series of solid base catalysts derived from F-Ca-Mg-Al layered double hydroxides (LDHs) with different NaF amount were prepared, characterized and tested for the transesterification reaction. The properties of the catalysts modified by fluorine have improved obviously. The catalytic activi…查看全部>>
