| 摘 要： | 采用硼酸三甲酯作为探针分子对Al2O3的路易斯碱性进行了红外光谱定量研究，Al2O3对硼酸三甲酯的吸附使硼酸三甲酯在1360cm-1的谱峰分裂成14199cm^-1和1287cm^-1两个峰，1036cm^-1的谱峰紫移到1067cm^-1，低压下吸收峰高与硼酸三甲酯压力成正比，与Al2O3含量成正比，结果表明Al2O3有一定的路易斯碱强度，与硼酸三甲酯之间的吸附是单分子层化学吸附。

| Abstract: | The Lewis base property of Al_2O_3 has been studied quantitatively with an infrared spectroscopic approach by using boric acid trimethyl ester (BATE) as the probe molecule. The adsorption of BATE by Al_2O_3 makes the 1360cm-1 absorb peak of BATE didived into two absorb peaks (1409cm-1 and 1287cm-1) and the 1036cm-1 absorb peak shifted to 1067cm-1. Under low pressure the height of the absorb peaks is direct proportion to the pressure of BATE and to the Al_2O_3 content. The results showed that there is certain strength of Lewis base with Al_2O_3 and the adsorption of BATE by Al_2O_3 is monomolecular chemical adsorption. |
