摘　　要：利用硅胶作载体,负载氯铬酸甲铵盐制备了一种新的载体铬(Ⅵ)氧化剂。该试剂制备方法简单、性质稳定。可在多种反应介质中对伯醇和仲醇氧化,高收率得到相应的醛和酮,反应操作简单,提纯方便。Methylammonium chlorochromate adsorbed on silica gel is described and evaluated as a convenient reagent for efficient oxidation of a variety of primary and secondary alcohols. This reagent is easily prepared and very stable. Primary and secondary alcohols are oxidized by the reagent into corresponding carbonyl compounds in good yields. The oxidation of alcohols with the reagent can proceed easily in some solvents,the oxidation condition is mild and the products are unique and easily separated.
