摘要：

Thermal stability of hydrazine nitrate (HN) in solutions in 4-12 M HNO3 in the temperature interval 70-150 degrees C was studied. Exothermic reactions accompanied by gas evolution arise in such systems under definite conditions. The intensity of such reactions depends on the component concentrations and temperature. The characteristics of the exothermic processes were determined to evaluate the explosion safety of process operations. Because of sharp pressure buildup in apparatuses, exothermic processes in the course of evaporation of HN-containing nitric acid solutions are hazardous from the viewpoint of radiation accidents.
