Synthesis of 2,2-Bis(4-hydroxy-3,5-dinitrophenyl)-propane and 2,2-Bis(4-hydroxy-3-nitrophenyl)-propane
【摘要】 双酚A在不同的w(HNO3 )溶液中硝化可得到不同的产物。在w(HNO3 ) =2 2 %的硝酸溶液中硝化 ,反应温度 30℃所得产物为 2 ,2 二 (4 羟基 3 硝基苯基 )丙烷 ,在w(HNO3 ) =6 3%的硝酸溶液中硝化 ,采用三段温度控制法 (0℃ - 30℃ - 5 0℃ )所得产物为 2 ,2 二 (4 羟基 3,5 二硝基苯基 )丙烷。产物经柱色谱纯化后 ,其元素分析、IR ,1HNMR ,13 CNMR和MS数据与结构相符
【Abstract】 Bis(4 hydroxyphenyl) propane was nitrified to different products by nitric acid with different concentration. When w(HNO 3)=22%, 2,2 bis(4 hydroxy 3 nitrophenyl) propane was obtained at 30℃ in 87.5% yield. When w(HNO 3)=63% and the reaction proceed under three period temperature controlling(0℃-30℃-50℃), 2,2 bis(4 hydroxy 3,5 dinitrophenyl) propane was obtained in 85.4% yield. The structure of the products were characterized by ultimate analysis, IR, 1H NMR, 13 C NMR and MS after purified by column chromatography.
【Key words】 bis(4 hydroxyphenyl) propane; 2,2 bis(4 hydroxy 3 nitrophenyl) propane; 2,2 bis(4 hydroxy 3,5 dinitrophenyl) propane; nitration;
