摘　　要：在高真空系统下研究了SnMe4与Pt修饰的HY沸石分子筛表面的接枝反应 ,并用元素分析、FT IR ,XRD ,DRS ,BET ,GC等表征了接枝产物的组成和性质。结果表明 :Pt/HY沸石的表面羟基可以与SnMe4在常温下反应 ,将三甲基锡基团接枝在沸石的超笼中。Pt/HY与SnMe4发生接枝反应后晶相结构没有改变 ,微孔体积和BET表面积都下降。The grafting reaction of SnMe 4 with Pt/HY zeolite was studied in a high vacuum. The grafted organometallic fragment -SnMe 3 had been characterized by several methods such as XRD, FT-IR and DRS. SnMe 4 could react with hydroxyl groups of Pt/HY at room temperature. X-ray diffraction studies showed that the zeolite had retained its crystalline structure after reaction with the tin compound. Its microporous volume and BET had decreased.
