Study of thermal analysis technology of sulfonated wheat--strew soda lignin
磺化麦草碱木质素热分析动力学研究

The thermal decomposition process of sulfonated wheat- strew soda lignin at the none-oxygen state was studied, using TG-IR and Non-isothermal Differential Scanning Calorimetry (DSC). The Kissinger and Ozawa equation kinetic parameters of the thermal decomposition were obtained. The apparent activation energy Ea, and pre-exponential factor, lnA, are 118.3 kJ•mol-1, 121.46 kJ•mol-1; 20.40min-1, 15.92min-1; respectively. The reaction order of the process is 1.8 by using Kissinger method.
