Scope

Main technical content: This standard specifies the technical requirements, test methods, inspection rules, and marking, packaging, transportation, storage, and safety of nitrosulfuric acid produced by chlorination. This standard applies to the tail gas generated during the chlorination (nitrochlorination reaction) process. After absorbing nitrogen oxides (NO, NO2) in the tail gas with sulfuric acid, nitrosulfuric acid is obtained, which is mainly used as an industrial raw material for diazotization reactions.
