摘　　要：以3-溴-5-氯水杨醛和间苯二胺为原料,通过缩合反应生成一种新的席夫碱BCMP,用紫外-可见光谱、红外光谱、核磁共振等对化合物的结构进行表征。同时采用TG/DTG联用技术,分别测定了BCMP在5、10、15、20 K/min不同升温速率下的热氧降解曲线。通过单扫描速率法和多重扫描速率法相结合的方法,确定其最可几的机理函数,计算反应的活化能。A new Schiff base of 3-bromo-5-chlorosalicylaldehyde-m-phenylenediamine was obtained by the condensation reaction of3-bromo-5-chlorosalicylaldehyde and m-phenylenediamine（abbreviated as BCMP） and confirmed by UV-Vis,IR and NMR. TG and DTG were used to elucidate the thermal oxidation degradation process and kinetics of BCMP in air at various heating rates of5,10,15,20 K/min.The activation energy and pre-exponential factor were calculated by the single scanning method and multiple scanning method.
