| 摘 要： | 文中以2，6-萘二磺酸钠为原料，成功地合成了2，6-萘二硫酚。研究了原料配比、反应时间、试剂纯度、氯化氢流量等因素对产率的影响。研究发现，合成中间产物2，6-萘二磺酰氯的最佳温度为110℃；合成目标产物2，6-萘二硫酚时，最佳反应温度为70℃，反应自始至终通入氯化氢，可以使产物的收率达80%以上。产物结构通过IR，1H-NMR和元素分析表征。

| Abstract: | A new synthetic approach to 2, 6-naphthalenedithiol was reported. Sodium 2, 6-naphthalenedisulfonate were used as reactants. The effects of the molar ratio of material，reaction temperature，refluxing time, purity of the reagent and the discharge of hydrochloride were investigated. Results show that 2，6-naphthalene disulfonyl chloride is obtained when the reaction temperature is 110℃ and that 2, 6-naphthalenedithiol can be well-obtained under following optimized conditions i.e. the reaction temperature of 70℃ and releasing hydrochloride from beginning to end, with the yield of more than 80%. The structure of 2, 6-naphthalenedithiol was characterized by IR, 1H-NMR spectrum and elementary analysis. |
