双酚A经硝化可制得合成阻燃剂的中间体2,2-二(4-羟基-3-硝基苯基)丙烷.最佳硝化条件为:w(HNO3)=22%,反应温度30 ℃,反应时间3 h,目标产物的产率最高达到87.5%.产物经柱色谱纯化后,其元素分析、红外光谱、核磁共振和质谱数据与结构相符.

Nitration of 2,2-bis(4-hydroxyphenyl)-propane by nitric acid gives 2,2-bis(4-hydroxy-3-nitrophenyl)-propane,an intermediate of fire-retardants.Experimental results show that under the best nitration conditions that the concentration of nitric acid is 22%,the reaction temperature is 30 ℃and the reaction time is 3 h,the highest yield of the target product is 87.5%.After purification with column chromatography,data of elementary analysis,IR, 1HNMR, 13CNMR...
