摘要：

Isopropanol and methylbutynol decomposition have been studied under He stream, at 483 K and 453 K, respectively, on different solids to characterize their basicity. The oxides studied included MgO, ZnO and the corresponding aluminates ZnAl2O4, ZnA12O7, MgAl2O4, Mg4Al2O7. We observe that isopropanol decomposition only occurs on ZnO and Zn aluminates, and is not observed on MgO and Mg aluminates, well known as basic oxides. In contrast, all the oxides studied are active towards methylbutynol with formation of acetone and acetylene.
