摘　　要：以TG-DTG为手段,研究了1,3,5-三(5,5-二溴甲基-1,3-二氧杂己内磷酰氧基)苯(TDDB)在氮气气氛中的热分解动力学,利用K issinger法、F lynn-W all-Ozawa(FWO)法对TDDB进行热分解动力学分析,求出该物质的热分解动力学参数,利用Coast-Redfen法研究该物质的热分解机理。结果表明:K issinger法所求得的活化能为344.48 kJ/mol,指前因子lnA为66.02;F lynn-W all-Ozawa法所求得的活化能为337.61 kJ/mol。TDDB的热分解的动力学方程为g(α)=α2,反应级数n=2。The thermal decomposition kinetics of the 1,3,5-tri （ 5,5-dibromomethyl-1,3 ,-dioxaphosphorinanyl-2-oxy） benzene（TDDB） were studied by TG-DTG techniques. The kinetic parameters,including the activation energy and frequency factor of the decomposition process for the title were calculated through the Kissinger and Flynn-Wall-Ozawa（FWO） method and the thermal decomposition mechanism of TDDB was also studied with the Coast-Redfem method. The results showed that the activation energy and pre-exponential factor were 344.48 kJ/mol and 66.02 s-1 with the Kissinger method and 337.61 kJ/mol with the Flynn-Wall-Ozawa method respectively. The kinetic equation of TDDB could be expressed as G（α） = α2, and the reaction order was n = 2.
