摘要：

Using a polymer-supported phase-transfer catalyst (PTC) and a redox mediator, Cl-/OCl-, the anodic oxidation of benzyl alcohol was studied. The polymer support used in this study was synthesized by the method of suspension polymerization. The results revealed that on decreasing the crosslinking and increasing the content of chloromethylstyrene in the polymer support, the number of phase transfer active sites, tri-n-butylphosphine, in the polymer-supported PTC increased. The anodic oxidation of benzyl alcohol in the presence of the redox mediator, Cl-/OCl-, and polymer-supported PTC occurred in the reaction controlled region when the stirring rate exceeded 400 r.p.m. The results also revealed that the current efficiency for the anodic oxidation of benzyl alcohol was mainly affected by the characteristics and weight of the polymer-supported PTC, the pH, and the concentration of benzyl alcohol. However, the temperature affected the current efficiency only slightly.
