The thermal degradation study of PLA with novel biofillers will provide insight into the determination of decomposition temperature, decomposition reaction pathway and byproducts [13].
Results show that (1) using critical temperature of thermal explosion, free energy of activation of decomposition reaction and self-accelerating decomposition temperature as criterions, the thermal stability, heat resistance ability and thermal safety of the three compounds decrease in the order of DNPP > MNPP >CNPP, but using energy gap and total energy as criterions, the thermal stability decreases in the order of DNPP > CNPP > MNPP, therefore, DNPP is the most stable compound among the three compounds; (2) Among of the three compounds, DNPP possesses the maximum theoretical density (1.

after 3 h milling) according to formula (2) is greater than 1KJ/mol, which is enough for the direct generation of single-cubic phase Co in cobalt oxalate during the thermal decomposition reaction (1) and to overcome the phase transformation during cooling, thus allowing it to maintain the structure even at room temperature (cubic-Co free energy of formation is 251 J/mol and the critical driving force of allotropic transformation is -160 J/mol) [4].

In general, storage decomposition is not a concern, but care should be taken not to store product in areas of high heat, such as near a heating radiator, as even when below the temperature of processing, a decomposition reaction may occur, albeit at reduced rate.
However, BD concentration was decreased more severely than the simulated result because the BD decomposition reaction by the acid catalyst seemed to occur more readily in the larger scale reactor (1000 ml) of this work than in the smaller flask reactor (150 ml) that was used to obtain the kinetic model.
The decomposition reaction is first-order, and is defined by the equation:
