摘要: H2O2与过渡金属构成的催化体系可选择性地氧化烃类化合物,如芳烃的羟基化和烯烃的环氧化等[1~3],且H2O2在应用中无环境污染,是一种颇有前途的氧化剂.有关金属催化H2O2与酮类化合物反应的报道很少.

Abstract: SnCl4·5H2Oand SnCl2·2H2O are the efficient catalysts for the oxidation of acetone with 30% hydrogen peroxide at room temperature to tetrametric acetone peroxide which is identified by molecular determination, elemental analysis, FT-IR, NMR, and MS. The catalytic activity of SnCl4·5H2O and SnCl2·2H2O is much higher than that of HCl. In the case of SnCl4·5H2O, the maximum yield of tetrametric acetone peroxide reaches 95.0%. The results show that the active species of catalytic reaction may be Sn4+.

Key words: Acetone, Hydrogen peroxide, SnCl4·5H2O, Catalytic oxidation, Macrocyclo peroxide
