摘 要:以二苯胺为原料,水和冰醋酸为溶剂,在酸性条件下一步合成二苯基联苯二胺,该方法具有操作简单,原料易得等优点。通过实验发现水和冰醋酸的体积比,反应温度和反应时间对收率有明显影响。由此对反应条件加以优化,得出反应的适宜条件是当水和冰醋酸的体积比为4,反应温度为30℃,反应时间为10 min时,收率可达78%。 |

Abstract:Diphenylbenzidine was synthesized by diphenylamine using glacial acetic acid and water as solvent in acidic condition. This method had many merits such as simple operation and cheap material. The optimum conditions were as follows: the volume proportion of water and glacial acetic acid was 4, the reaction temperature was 30℃ and reaction time was 10 minutes. The yield rate of product was 78%. |
Key words:diphenylamine; diphenylbenzidine; synthesis |
