摘　　要：通过吡啶吸附红外光谱分析了蒙脱石 (EC1)、蒙脱石 -氯化铁 (EC4 ( )、EC4 ( )、EC7、EC9)特征吸收峰的相对强度。在 EC4 ( )、EC4 ( )、EC7、EC9中 ,B酸 1 540 cm-1吸收增强 ,而 L酸在1 44 0 cm-1吸收所占总酸量的比例下降。对于苯与氯化苄的反应 ,L酸 1 44 0 cm-1附近吸收所占总酸量的比例越小 。Relative intensity of special absorption of montmorillonte (EC 1) and montmorillonite iron chloride (EC 4(Ⅱ), EC 4(Ⅲ), EC 7, EC 9) was analysed by IR spectra of the samples after pyridine absorption. Absorption of B acid at 1540 cm -1 was greater in EC 4(Ⅱ), EC 4(Ⅲ), EC 7, EC 9 than in EC 1. The rate of L acid at 1440 cm -1 to total acid in EC 4(Ⅱ), EC 4(Ⅲ), EC 7, EC 9 was reduced. The less rate of L acid at 1440 cm -1 to total acid the more intensive is the catalytic property for the reaction between benzene and benzyl chloride.
