1,2-aceanthrylenedione was synthesized through the acylation reaction of anthracene andoxalyl chloride catalyzed by anhydrous AlCl3. The effects of various reaction conditions on the yieldand selectivity of 1, 2-aceanthrylenedione were studied by GC analysis. The results show that theoptimum synthesis conditions of the acylation reaction are as follows : the molar ratio of oxalylchloride to anthracene being 1:2, the molar ratio of anhydrous AlCl3 to anthracene being 4:1, thereaction time being 5 h, the reaction temperature being 303k and the solvent of the reaction systembeing CS2. Under those conditions, the yield and selectivity of 1, 2-aceanthrylenedione is 83.8 % and92.3% respectively. Pure 1, 2-aceanthrylenedione was prepared by extraction and recrystallation. Thestructure of 1, 2-aceanthrylenedione was identified by measure of melting point, GC/MS, FTIR and1HNMR analyses
