  In the purification of crude tetrachlorophthalic anhydride containing hexachlorobenzene as impurities, this invention relates to purification by decomposition in which crude tetrachlorophthalic anhydride is contacted with chlorine gas in fuming sulfuric acid or sulfuric anhydride in the presence of iodine or iodine trichloride to decompose the impurities and remove them or purification by washing in which hexachlorobenzene is separated by washing with a chlorinated solvent. This invention also relates to a process for purifying crude tetrachlorophthalic anhydride containing iodotrichlorophthalic anhydrides as impurities by applying a radical reaction treatment in a chlorinated solvent to convert iodotrichlorophthalic anhydrides to tetrachlorophthalic anhydride. Moreover, it relates to high-purity tetrachlorophthalic anhydride containing 10 ppm or less of hexachlorobenzene. With the process of this invention, it is possible to recover high-purity tetrachlorophthalic anhydride with extremely low contents of impurities readily in high yield.

  在提纯含有六氯苯杂质的粗四氯邻苯二甲酸酐时，本发明涉及分解提纯法，即在碘或三氯化碘存在下，将粗四氯邻苯二甲酸酐与发烟硫酸或硫酐中的氯气接触，使杂质分解并除去；或洗涤提纯法，即用氯化溶剂洗涤分离六氯苯。本发明还涉及一种提纯含有碘三氯邻苯二甲酸酐杂质的粗四氯邻苯二甲酸酐的工艺，其方法是在氯化溶剂中进行自由基反应处理，将碘三氯邻苯二甲酸酐转化为四氯邻苯二甲酸酐。此外，本发明还涉及高纯度四氯邻苯二甲酸酐，其六氯苯含量不超过 10 ppm。采用本发明的工艺，可以高产率回收杂质含量极低的高纯度四氯苯酐。
