ABSTRACT
The thermal decomposition of recrystallised BHC and dusting powder (DP) containing 50 % was studied using thermogravimetry (TG) and differential thermal analysis (DTA) techniques. The behavior of isomeric constituents has also been studied. From thermogravimetric curves the order (n) and activation energy (Ea) have been elucidated. Additives present in DP have accelerated the rate of decomposition reaction. However, it did not affect the melting endothermic DTA peaks.
