- Thermal decomposition behavior of bis (4-nitrophenol)-2,4,6-triamino-1,3,5-triazine monohydrate (BNPM) has been studied by means of thermogravimetric analysis at three different heating rates 10, 15 and 20°C min¯¹. Non-isothermal studies of BNPM have revealed that the decomposition occurs in three stages involving dehydration and decomposition. The values of effective activation energy (E_{a}), pre-exponential factor (A) of each stage of thermal decomposition for all heating rates were calculated by model free methods: Arrhenius, Flynn-Wall, Friedman, Kissinger and Kim-Park method. A significant variation of effective activation energy (E_{a}) with conversion (α) indicates that the process is kinetically complex. The linear relationship between the A and E_{a} values was well established (compensation effect). Dehydration stage was governed by the Avrami-Erofeev model (A2) and decomposition stages were governed by the Avrami-Erofeev model (A4).
