| Abstract：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. |
| Key words：phthalic anhydride; diiodophthalic anhydride; synthesis; |
