| 摘 要： | 以三光气和对硝基苯胺为原料,合成对硝基苯异氰酸酯,考察了溶剂及用量、反应时间和原料配比对收率的影响。结果表明,合成对硝基苯异氰酸酯适宜的反应条件为:以乙酸乙酯为溶剂,用量120 mL,反应时间5 h,对硝基苯胺与三光气的摩尔比为2∶1。在上述适宜条件下,对硝基苯异氰酸酯的收率可达66.0%。

| Abstract: | p-Nitrophenyl isocyanate was prepared from triphosgene and p-nitroaniline.The effects of solvents and its content,reaction time and the mole ratio of raw materials on the yield of p-nitrophenyl isocyanate were studied.The optimum reaction conditions were obtained as follows:the solvent ethyl acetate(its content) 120 mL,the mole ratio of p-nitroaniline to triphosgene 2 ∶1 and reaction time 5 h.The results of parallel tests showed that under such optimum condition the yield of p-nitrophenyl isocyanate could reach 66.0%. |
