采用月桂酸作表面活性剂相转移制备了 Cu-Mn合成甲酸甲酯催化剂 ,结果发现相转移法制得的催化剂粒径比采用共沉淀法要小得多 ,已经达到了纳米超细粒子水平。同时 ,比表面积也显著增大 ,用于由合成气一步法合成甲酸甲酯的活性显著高于共沉淀法及浸渍法制得的催化剂。
The phase transition of lauric acid as surfactant was used to prepare Cu-Mn for methyl formate. The results showed that the particle size of catalyst prepared by phase-transfer method was much smaller than that of coprecipitation, which reached the level of nanometer ultrafine particles. At the same time, the specific surface area also increased significantly, and the activity for synthesizing methyl formate from syngas was significantly higher than that of coprecipitation and impregnation.
