Experimental study of the kinetics of the reactions of 2-sulfobenzoic acid imide (saccharin) and benzenesulfonamide with 3-nitrobenzenesulfonyl chloride in a 1,4-dioxane-water mixture (80:20 by weight) in the temperature range 298–318 K has shown that both compounds are low reactive (k298 = 1.66 × 10−4 and 3.37 × 10−3 L mol−1 s−1, respectively). The activation barriers to these reactions exceed 50
在1,4-二恶烷-水混合物(重量比为80:20)中,在298-318 K的温度范围内,2-磺基苯甲酰亚胺(糖精)和苯磺酰胺与3-硝基苯磺酰氯反应的动力学研究结果表明这两种化合物都是低反应性的(k 298分别为1.66×10 -4和3.37×10 -3 L mol -1 s -1)。这些反应的激活势垒超过50 kJ / mol。推荐使用二恶烷水溶液作为制备N-(苯磺酰基)-3-硝基苯磺酰胺的溶剂,产率最高可达87%。
