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.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.
