[摘要]:Palygorskite, a natural, environmentally friendly and inexpensive fibrillar silicate clay mineral, was applied as a catalyst in the oxidation of alcohols in aqueous media. The oxidation transformation effectively proceeded in the presence of an environmentally benign oxidant Oxone (R). Benzyl alcohols, benzhydrols, cyclic and aliphatic alcohols could be oxidized to their corresponding acids or ketones in moderate to high yield and good selectivity at 50 degrees C or 70 degrees C in 21 hours. |
