摘　　要：The stabilities of benzotrifuroxan(BTF) and the PBX based on BTF were compared.The Bourdon method was used to investigate the thermal decomposition of BTF and the PBX under vacuum conditions.Within the temperature range from 80 to120℃,the relationships between the time(τ) corresponding to the reacted fraction of 0.1% and the temperature(T) of the thermal decomposition of BTF and the PBX can be expressed by the following equations:lgτ=5.6144-0.05354T and lgτ=5.6836-0.04865T.Therefore the storage lifes of BTF and the PBX at 30℃ extrapolated by Berthelot equation were seperately 27.9 years and 45.9 years.The results indicated that PBX based on BTF has better thermal stability than BTF.The stabilities of benzotrifuroxan（BTF） and the PBX based on BTF were compared.The Bourdon method was used to investigate the thermal decomposition of BTF and the PBX under vacuum conditions.Within the temperature range from 80 to120℃,the relationships between the time（τ） corresponding to the reacted fraction of 0.1% and the temperature（T） of the thermal decomposition of BTF and the PBX can be expressed by the following equations：lgτ=5.6144-0.05354T and lgτ=5.6836-0.04865T.Therefore the storage lifes of BTF and the PBX at 30℃ extrapolated by Berthelot equation were seperately 27.9 years and 45.9 years.The results indicated that PBX based on BTF has better thermal stability than BTF.
