Thermal Decomposition and Safety Assessment of N-Nitrodihydroxyethyl Dinitrate by DSC and ARC

Abstract—N-Nitrodihydroxyethyl dinitrate (DINA), an explosive as well as high-energy plasticizer, was widely used in double-base propellant production. In this paper, the thermal explosion hazard and decomposition progress of DINA under dynamic and adiabatic conditions were investigated using differential scanning calorimeter (DSC) and accelerating rate calorimeter (ARC) respectively to acquire thermodynamic parameters (e.g. Tonset, Tp and ΔHd) for self-heat reactions. The specific heat capacity was calculated based on a linear ramp method using DSC. Futhermore, we carried out these tests, which can provide more useful information for determining the decomposition kinetic parameters (Ea and A) and thermal hazard parameters (ΔG≠, ΔH≠, ΔS≠, Tb and TD24) under the non-isothermal and adibatic conditions, respectively. The SADT predictions for the 5, 20 and 50 kg packages of DINA and some simulation for spatial distribution of T and α have been performed using the finite element analysis method of AKTS software, which can help us to optimize the conditions of storage and transportation for chemical, also minimize industrial disasters.
