本文详细考察了固体酸SO_4~(2-)/TiO_2-Al_2O_3的制备条件对其酯化活性的影响,并对催化剂进行了X光电子能谱和红外光谱分析,作者指出:催化剂的制备条件对其酯化活性有极大的影响。催化剂表面同时存在质子酸中心和路易斯酸中心。同时作者建立了催化剂酸中心模塑和表面物质结构模型。
In this paper, the effects of the preparation conditions of solid acid SO 4 2- / TiO 2 -Al 2 O 3 on the esterification activity were investigated in detail. The catalysts were analyzed by X-ray photoelectron spectroscopy and infrared spectroscopy. The author pointed out that the preparation conditions of the catalyst Esterification activity has a tremendous impact. The catalyst surface has both protonic acid and Lewis acid centers. At the same time, the author established a catalyst acid center molding and surface structure model.
