摘要
报道了二碘代苯酐的合成研究。以邻苯二甲酸酐为原料 ,烟酸为溶剂 ,碘为卤化试剂的直接碘化法制得二碘代苯酐。运用正交试验研究了反应的主要影响因素 ,得到了较佳制备条件 :碘 /苯酐 (mol/mol)为 1 1∶1,反应温度 50℃ ,反应时间为 12h ,产率 81 3%。
The paper focused on the study of synthesis of diiodophthalic anhydride. Diiodophthalic anhydride were produced by the reaction of phthalic anhydride with iodine in oleum. The main factors affecting the reaction was studied through orthogonal experiments. Under the optimum conditions, the yield is 81.3%. The structure of the product was characterized by IR and UV spectrum analysis.
