| 摘 要： | 由正己醇合成正己酸不仅可以提高附加值，还能生产己酸类香料以及多种医药产品．利用杂多过氧磷钨季铵盐催化剂，以对环境友好的H2O2 为氧化剂催化十八醇氧化成十八酸的研究已有报道［1,2],但合成负载型相转移催化剂并用于本课题的研究还未见报道．由于过氧磷钨十八烷基季铰盐催化剂（POWP）通常只有很小的比表面积，而SiO2不仅有大的比表面积，同时它所具有的表面羟基是杂多化合物的良好载体［2]，POWP负载后的催化剂（POWPS）与未负载的POWP相比，将正己醇氧化为正已酸的收率提高了10多个百分点．

| Abstract: | Abstract The factors influencing the catalytic properties for the oxidation of hexanol to hexanoic acid over SiO2 supported peroxotungsto-phospho-quaternary ammonium catalyst were investigated. The catalysts were characterized by means of IR and BET techniques. The influence of different reaction conditions such as reaction temperature, reaction time, amount of hydrogen peroxide and catalyst was discussed for the oxidation reaction. The optimal reaction conditions were given. SiO2 supported POWP catalysts are obviously superior to the unsupported POWP under the same reaction condition. |
