The efficient catalysts were designed to allow the entry and release of reactants and products into the mesoporous SBA-15 in which the active sites, peroxophosphotungstate, were entrapped by silylation with three different silylating agents (C₃, C₅, and C₈ arm). The as-prepared catalysts were characterized by elemental analysis, ICP analysis, TGA, XRD, N₂ adsorption/desorption, SEM, TEM, and FT-IR spectra. Their catalytic performances were tested for the epoxidation of soybean oil using different parameters such as temperature, H₂O₂ to unsaturation molar ratio, catalyst loading and stirring speed. The resulting epoxidized soybean oil was analyzed qualitatively and quantitatively by FT-IR and ¹HNMR. The results confirmed that the catalyst silylated with C₈ arm is promising for the synthesis of epoxides of long-chain carbon and reusable at least three times without obvious decrease in activity. Moreover, use of H₂O₂ oxidant and free of solvent in the epoxidation reaction are the main advantages of these catalysts.

设计有效的催化剂，以允许反应物和产物进入和释放到中孔SBA-15中，在该孔中，活性位点过氧磷钨酸盐被三种不同的甲硅烷基化剂（C ₃，C ₅和C ₈臂）甲硅烷基化而包埋。。制备的催化剂通过元素分析，ICP分析，TGA，XRD，N ₂吸附/解吸，SEM，TEM和FT-IR光谱进行表征。使用不同的参数（例如温度，H ₂ O _2）对大豆油的环氧化性能进行了测试。到不饱和摩尔比，催化剂负载量和搅拌速度。通过FT-IR和¹ HNMR对所得的环氧化大豆油进行定性和定量分析。结果证实，用C ₈臂甲硅烷基化的催化剂有望用于长链碳环氧化物的合成，并且至少可重复使用3次而活性没有明显降低。此外，在环氧化反应中使用H ₂ O ₂氧化剂且不含溶剂是这些催化剂的主要优点。
