摘　　要：二苯胺(Diphenylamine)是一种重要的工业原料。二苯胺作为橡胶抗氧剂、染料、杀菌剂和医药中间体有广泛的应用。在军工行业中,二苯胺由于能够结合炸药药剂的降解物从而延缓炸药的分解,作为炸药的安定剂和钝化剂。The paper present study on the methods of extracting diphenylamine from firework reagents and the conditions of determining diphenylamine with GC.The diphenylamine in firework samples were extracted with anhydrous ethyl alcohol and Proportion of fireworks regents and extracting solvents was 32:1,making using of ultrasonic assisted extraction,extracting time was 30 minutes,mesh number was 40.It appears linear correlation from Omg/L to 200mg/L with above methods(r=0.9999),RSD was 0.018%in same sample(n=10)、the detection limit concentration was 0.43mg/L,The coefficient of recovery was 95.8%-101.2%.The method is simple、rapid、and suitable for the diphenylamine determination in fireworks reagent.
