间硝基苯基-β-羟乙基砜的合成改进及表征

用环氧乙烷代替氯乙醇与间硝基苯亚磺酸钠缩合，得间硝基苯基－β－羟乙基砜，收率９０％以上，而氯乙醇法为８２％。产品纯度也较氯乙醇法高。纯品间硝基苯基－β－羟乙基砜为白色固体，熔点７７～７８℃。用ＩＲ、１Ｈ－ＮＭＲ和１３Ｃ－ＮＭＲ对纯品进行了表征

Synthetic Modification and Characterization of 2 [(3 Nitrophenyl)sulfonyl]ethanol

Nitrophenyl)sulfonyl]ethanol(NPSE)was synthesized by reaction of sodium 3 nitrophenyl sulfinate with ethylene oxide instead of chloroethanol at 60℃ for 6 hrs.The yield of the NPSE was more than 90%.By comparison of chloroethanol as reactant,the yield was 82%.The purity of the NPSE obtained by ethylene oxide method was higher than that of chloroethanol method.The pure NPSE was characterized by IR, 1H NMR and 13 C NMR.It is a white solid,mp is 77～78℃。
