煤基活性炭共价固载铬离子有机配合物催化剂的制备研究

Preparation of Coal Based Activated Carbon Covalently Immobilized Chromium Complexes Catalyst

采用煤基活性炭为载体,通过20%稀HNO3氧化处理,先后接枝(Me O)3Si(CH2)3Cl、α-氨基戊二酸,络合反应,成功制备了含双羧基双齿配体配合铬离子催化剂,其结构通过FT-IR、SEM、XRD等手段得到确证。

Coal based activated carbon activated carbon was used as carrier to covalently immobilize Cr3 ＋ complexes. After 20% HNO3 oxidation treatment. New types of double carboxyt - containing bidentate ligands were subsequently synthesized by grafting the oxidized coal based activated carbon with （ MeO）3Si （ CH2 ）3Cl,α - amin oglutaric acid ,complexation reaction. The samples were characterized by FT - IR, SEM and X - ray diffraction.
