The thermal behavior of nitrocellulose (NC) containing diphenylamine (DPA), 2-nitrodiphenylamine (2-NO2-DPA), N-nitro-sodiphenylamine (N-NO-DPA), ethyl centralite (EC), akardite 11 (AKII), 1, 1,3-tri-(2-methyl-4-hydroxy-5-tert-butyl-phenyl)-butane (BP,,,,,.), 3-(3,5-di-tert-butyl-4-hydroxy-phenyl)-propionic acid oc- tadecyl ester (BPhin, and 3-(3-tert-butyl-4-hydroxy-5-methyl-phenyl)-propionic acid 2-(9-12-[3-(3-tert-butyl-4-hydroxy-5-methyl-phenyl)-propionyloxy]-1,1-dimethyl-ethyll-2,4,8,10-tetraoxa- spiro [5.5] undec-3-yl)-2-methyl-propyl ester (BPsemi) was observed during isothermal storage at 393 K using a C80 micro-calorimeter. The results indicate that each stabilizer decreased NC's maximum beat release rate and increased the induction period of heat release. We also observed that the maximum heat release rate and the induction period were dependent on the amount of stabilizer. DPA decreased the maximum heat release rate to the greatest extent, with the other stabilizers having similar effects on the decrease of maximum heat release rate. AKII prolonged the induction period of heat release most. The order of prolongation of the induction period was AKII > 2-NO2-DPA approximate to DPA > N-NO-DPAzz approximate to EC > BPless BPsemi BPhin.
