摘要：
Bis (2,2- dinitropropyl) fumarate (BDNPF) as a melt cast explosive can be used alone or in combination with inert melt castable thermoplastic elastomer (TPE) diluents. In this work, the BDNPF synthesized and the structure of it were verified by IR, and H-1-NMR spectroscopy. The thermal stability of BDNPF was studied by differential scanning calorimetery (DSC) and thermogravimetery (TG) techniques. The influence of the heating rate (5, 7, 10 and 15 degrees C/min) showed that with increased heating rate the decomposition temperature of the compound rose. Also, the kinetic parameters such as activation energy and frequency factor for this compound were obtained from the DSC-TGA data by non-isothermal methods proposed by ASTM E698 and Flynn-Wall-Ozawa (FWO). The critical temperatures were estimated at 241.61 degrees C and 241.85 degrees C for BDNPF by using ASTM and Flynn-Wall-Ozawa data, respectively.
