| 摘 要： | 提出了在由四苯基环戊二烯酮和顺丁烯二酸酐制备四苯基邻苯二甲酸酐时，用加热脱氢代替加溴脱氢，并对加热脱氢的条件（加热到２６０～２７０℃）进行了探讨。结果表明，加热脱氢是可行的，既简化操作又降低消耗。

| Abstract: | In this paper, the tetraphenylphthalic anhydride is prepared with tetraphenylcyclopentadienone and maleic anhydride by the heating dehydrogenation instead of adding bromine,And make an approach to the conditions of heating dehydrogenation (heating to 2600～270℃). The results show that this method is feasible,its operation is simplified and its consumption is reduced. |
