摘要
The thermal stability of 5-12 M HNO3 solutions containing 5-50 g/L acetohydroxamic acid was studied at atmospheric and above atmospheric pressure. It was established that at temperatures below the boiling point, solutions undergo weak exothermic oxidation processes, accompanied by gas evolution. The problem of explosion safety in the evaporation of nitric acid solutions containing acetohydroxamic acid is analyzed based on the obtained characteristics of exothermic processes.
