溴代苯酐的制备

Synthesis of Bromophthalic Anhydride

以邻苯二甲酸酐为原料，在金属铁作用下，与液溴发生溴代反应，制得溴代苯酐，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，收率达７５．３％。用红外光谱及紫外光谱对产品结构进行了表征。

The paper focused on the study of synthesis of bromophthalic anhydride. Bromophthalic anhydride was produced by the reaction of phthalic anhydride with bromine water under the catalysis of ferrum powder. The main factors affecting the reaction were studied through orthogonal experiments. Under the optimum conditions, the yield was 75. 3%. The structure of the product was characterized by IR and UV spectrum analysis.
