Some 4-(substituted phenylsulfonamido)benzoic acids have been synthesized by fly-ash:H3PO3 nano catalyst catalyzed condensation of substituted benzenesulfonyl chlorides and 4-aminobenzoic acid in ultrasound irradiation conditions. The yields of the sulfonamides are more than 90%. The synthesized 4-(substituted phenylsulfonamido) benzoic acid derivatives were characterized by their physical constants
通过粉煤灰:H3PO3纳米催化剂在超声辐射条件下催化取代苯磺酰氯与4-氨基苯甲酸的缩合反应,合成了一些4-(取代苯基磺酰胺基)苯甲酸。磺酰胺的产率超过90%。合成的4-(取代的苯磺酰胺基)苯甲酸衍生物的物理常数,分析数据和光谱数据均得到了表征。所有磺酰胺类药物的抗菌活性均通过Bauer-Kirby纸片扩散法进行测定。
