The Critical Temperature of N-Nitro-Dihydroxyethylami Nitration Reaction

Abstract

The nitration reaction is one kind of important reaction in many synthetic chemical reactions. The reaction with a high temperature releases a lot of heat and is easy to get out of control. The energetic materials is the main ingredients of the reaction mixture in late of nitrification of energy-containing materials, the accident about burn or rapid energy release will happen once the reaction is out of hand. There are so many thermal safety studies of energy materials, but the thermal safety research about energy material nitrification production line is not reported. Using the designed multi-scale energy material test, the thermal stability of DINA (N-Nitro-dihydroxyethylami) nitration reaction mixture was studied. The critical ignition temperature about different scale was obtained, and this temperature can be used as the base of enterprise process safety design.
