摘　　要：The Keggin-type heteropolyacids（HPAs）, as the new multifunctional catalysts,show excellent activity for various homogeneous reactions. In recent years, the HPAshave been applied to many industrial processes. Heterogenization of the HPAswould make the homogeneous reactions heterogeneous, which is more easily applicableand has aroused great interest of chemists. This note reports the heterogenization of12-silicotungtic acid (SiW₁₂)with the chemically treated bentonite as the support.
