N,N'-乙撑双硬脂酰胺的热分解动力学研究
Research on Thermal Decomposition Kinetics of N,N'-Ethylenebis (stearamide)
摘要
Abstract
Thermal decomposition characteristics and kinetics of N,N'-ethylenebis(stearamide) (EBS) were investigated under high purity nitrogen atmosphere by DTA-TGA techniques. The thermal decomposition kinetic parameters of EBS were calculated by Flynn-Wall-Ozawa, Kissinger and Šatava-Šesták methods, and the decomposition mechanism was also studied. The results show that the thermal decomposition process contains two stages at 519.15~723.15 K. For the first and second stages, the activation energies are 78.41 and 88.38 kJ . mol-1 respectively, and the pre-exponential factors are 2.188×108 and 7.586×108 min-1, respectively. Moreover, the integral equations for the decomposition mechanism of the two stages are g(α) = 1-(1-α)2 and g(α) = α, respectively. The data obtained provide fundamental information for industry production and application of EBS.关键词
