摘　　要：采用浸渍法,将硅钨酸(HSiW)负载到于Worm-like介孔材料上制备固体酸催化剂,XRD和FT-IR表征表明,HSiW成功负载于介孔材料上,并且随着HSiW负载量增加,比表面积和孔容逐渐减小。负载型HSiW固体酸催化剂用于癸二酸二辛酯的合成反应,在反应温度120℃、n(癸二酸)∶n(异辛醇)=1∶3、反应时间3.0 h和HSiW负载质量分数50%条件下,催化活性最高,酯化率达99.66%,催化剂易于回收,可重复使用。The silicotungstic acid （HSiW）solid acid catalysts supported on mesoporous materials were preparedby impregnation method and characterized by means of X ray diffraction and Fourier transform infrared spectroscopy. The results of characterization suggested that HSiW was successfully supported on Worm- like mesoporous materials, and their specific surface area and pore volume gradually decrease with the increase of HSiW loadings. The experimental results of dioctyl sebacate synthesis showed that 50% HSiW- Worm- like catalyst exhibited the highest activity and the maximum esterification rate reached 99.66% under the condition of reaction temperature 120 ℃, molar ratio of sebaeic acid to isooetyl alcohol 1 ： 3, reaction time 3 h and HSiW loading mass fraction 50%.
