摘 要:以HMS(NH2)、HMS-PAMAM(G0)、HMS-PAMAM(G1)、HMS-PAMAM(G2)為載體,采用化學(xué)接枝法合成了4種Salen-Mn固相催化劑;用紅外光譜、熱重分析和滴定分析等手段對其進(jìn)行了表征,并考察了它們在反式二苯乙烯環(huán)氧化反應中的催化活性。結果表明隨著(zhù)HMS-PAMAM代數的增加,催化劑催化活性增強,轉化頻率降低,催化劑重復使用性能較好。 |

Abstract:HMS(NH2), HMS-PAMAM(G0), HMS-PAMAM(G1) and HMS-PAMAM(G2) were separately used as the carriers for the immobilization of Salen-Mn and their applications in the epoxidation of E-stilbene were studied. The results showed that the catalytic activities increased by increasing HMS-PAMAM, but TOF reduced, the heterogeneous catalysts were stable and can be recycled. FT-IR, TG-DSC and titration were applied for the characterization of the catalysts |
Key words:HMS-PAMAM; Salen-Mn; immobilization; epoxidation |
