相转移法制备Cu-Mn合成气一步法合成甲酸甲酯催化剂

PHASE TRANSFER PREPARATION OF Cu-Mn METHYL FORMATE SYNTHESIS CATALYST DIRECTLY FROM SYNTHESIS GAS

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。

Cu Mn methyl formate synthesis catalysts have been prepared with phase transfer using lauric acid as a surfactant.The results indicate that the thus catalysts obtained have smaller particles size and higher specific area than the one by coprecipitation and impregnation.Moreover,the reaction activity of the one step synthesis of methyl formate directly from synthesis gas is obviously higher than those by coprecipitation and impregnation.
