| 摘 要： | 研究了在乙酸中，用H2O2氧化1-萘胺合成1,4-萘醌的新方法。 考察了反应温度、反应时间、1-萘胺与H2O2摩尔比、硫酸和H2O2质量分数等因素对产品收率的影响。 得到较优的反应条件为：1-萘胺与H2O2摩尔比为1∶10、H2O2质量分数为5%、硫酸质量分数为45%、反应温度为80 ℃、反应时间为3 h。 在此条件下，1,4-萘醌的收率为52.2%。 该方法具有操作简单、反应时间短和产物易分离等优点。

| Abstract: | A new process was developed to oxidize 1-naphthylamine by H2O2 in acetic acid for preparing 1,4-naphthoquinone. The effects of the reaction temperature, the oxidation time, molar ratio of 1-naphthylamine to H2O2, the concentration of sulfuric acid and the concentration of H2O2 on the product yield were investigated. The optimal reaction conditions for preparing 1,4-naphthoquinone with yield higher than 52.2% are as followings:the molar ratio of 1-naphthylamine to H2O2 is 1∶10, the mass concentration of H2O2 is 5%, the mass concentration of sulfuric acid is 45%, reaction temperature is 80 ℃, and reaction time is 3 h. This method has the advantages such as simplicity, easy separation of the product and short reaction time. |
