Abstract
3'-Amino-4-acetamido-benzenesulfonanilide,a dye intermediate was synthesized.The factors affecting the yield of sulfoamidation were investigated.The results showed the optimum reaction condition was 20℃,pH8.0~9.0,n(4-acetamidobenzenesulfonyl chloride):n(m-phenylenediamine)=1.3∶1.0,and the highest yield was 84.2% under this condition.The structure of the product was characterized by IR,1H-NMR.
