负载型壳聚糖双水杨叉乙二胺合钴配合物的制备及其对乙硫醇的催化氧化
Chitosan Coordinated CoSalen and Its Catalytic
Activity in Oxidation of Ethanethiol
摘要
Abstract
A silica-supported catalyst, CoSalen (Co (Ⅱ) complex of bis (salicylideneethylenediamine)) coordinated with chitosan (SiO2-CS-CoSalen), was prepared. The chitosan film coated onthe silica surface was characterized through elemental analysis, IR, fluorescence spectrophotometry,ESR and XPS. It is found that the coordination is realized through binding of N in chitosan with theCo ( Ⅱ ) in CoSalen complex. Because the site isolation effect present in CS-CoSalen may inhibit theformation of dimers and μ-oxo-dimers of CoSalen, the coordinated CoSalen showed a more efficient ac-tivity in the oxidation reaction of ethanethiol than the monomeric omplex.
