Moles of NaOH consumed to neutralize the same amount of acidic sites are always greater than those of butylamine, this difference is due to the surface concentration of Lewis sites. Suppose that the interaction of NaOH with surface acidic sites in aqueous solution occurs according to the following stoichiometric relation: one mole Bronsted acid ...             用正丁胺滴定和吡啶—红外光谱法,研究了LaHY表面上酸性中心与NaOH的作用机理及酸性表面性质。NaOH与LaHY表面上酸性中心作用的计量比与正丁胺滴定时不同。中和同样数量的酸性中心所消耗NaOH的当量数比正丁胺多,其差值与Lewis酸的含量有关。假定NaOH与LaHY表面上酸性中心作用的机理为:一当量Bronsted酸与一当量NaOH作用,而一当量Lewis酸消耗两当量NaOH,则可借助正丁胺滴定和NaOH中和法测定Bronsted酸和Lewis酸的含量。红外光谱测定的结果支持这一观点。 研究结果还表明,LaHY表面的酸性分布是不均匀的,异丙苯裂解反应是在不同强度的酸性中心上进行的。不同强度的酸性中心对总活性的贡献不同,而贡献的大小又与反应温度有关。 文摘来源          The research work on hetero-atom isomorphous substitution of framework atom in large pore silica-alumina zeolites occurred in literatures is reviewed in detail.
