用柱层析硅胶作固定相 ,以苯∶乙酸乙酯 =5 .5∶1 体系作为色谱性的淋洗剂。用柱色谱法提纯新试剂 2 -羟基 -4-磺酰氨基苯重氮氨基苯 ,并对提纯试剂的结构用红外光谱和核磁共振谱进行了表征。结果令人满意。
Column chromatography on silica gel as the stationary phase, benzene: ethyl acetate = 5 .5: 1 system as a chromatographic eluent. The new reagent 2 - hydroxy - 4 - sulfonamidobenzenediazonitrobenzene was purified by column chromatography. The structure of the purified reagent was characterized by IR and 1H - NMR. The result is satisfactory.
