摘　　要：以对氨基苯磺酸与三聚氯氰进行亲核取代反应,合成6-氯-2,4-二(4-磺酸苯氨基)-1,3,5-三嗪。然后以其为醚化剂,玉米淀粉为原料,制备含磺酸基的阴离子淀粉。对产物结构进行表征;对产物的吸附性能进行探讨分析。结果表明,随着醚化剂用量的增加,产物取代度增大,亚甲基蓝去除率亦增大,且当醚化剂与淀粉质量比为3.5∶5时,亚甲基蓝去除率达91.56%.6-chloro-2,4-bis(4-sulfonic aniline)-1,3,5-triazine was synthesized by nucleophilic substitution reaction of p-aminobenzenesulfonic acid and cyanuric chloride.Starch derivative containing sulfonic acid group was prepared using corn starch as the raw material and 6-chloro-2,4-bis(4-sulfonic aniline)-1,3,5-triazine as etherifying agent.The product was characterized and the adsorption ability of the product was analyzed.The results showed that with the increase of the amount of etherifying agent,degree of substitution(DS)of the product increased,and the methylene blue removal rate increased too.When the mass ratio of etherifying agent and anionic starch was 3.5∶5,the removal rate was 91.56%.
