The volatilization rate of DNTF is researched by designing experiment ,comparing the volatilization rate of TNT and DNAN are researched. The influence factors of volatilization rate are researched, The results indicated that the volatilization rate of DNTF is equal with the volatilization rate of DNAN and it relates temperature, molecular weight, and vapor pressure, this can provide the basis for DNTF based explosive process design.
