摘　　要：以微乳化法制备的二氧化硅担载的的杂多酸催化剂Cu-H4SiW12O40在室温下能瞬间催化四氢吡喃化反应。且催化剂在至少重复使用四次而未见明显的失活。Silica-impregnated Cu-H_4SiW_(12)O_(40) was found to be an efficient heterogeneous catalyst for the tetrahydropyranylation of alcohols. The reaction was very quickly (within 5 second) and the catalyst could be reused for at least 4 times without obviously lowering of its activity.
