The heat release effects of three kinds of typical reaction process of energetic compounds were determined using calorime-ter,including nitrification of urea,oxidation of DATF,azidation of DINA. Results show that,the heat of reaction of the nitration of urea is 1. 63 kJ·g-1 and the maximum heat release rate is 174. 7 W,the heat of reaction of the oxidation of DATF is 2. 26 kJ·g-1 and the maximum heat release rate is 64. 7 W,the heat of reaction of the azidation of DINA is 0. 88 kJ·g-1 and the maximum heat release rate is 90. 1 W. At the same time,the change curve of heat transfer coefficient and heat capacity of reaction system have been measured.
