Nitrosylsulfuric acid Usage And Synthesis
Chemical Properties Yellowish viscous liquid
Uses Nitrosylsulfuric acid is used for diazotisation, nitrosation, oxidation and oximation reactions. Product Data Sheet
General Description Shipped in solution with sulfuric acid (solutions are usually 40% Nitrosylsulfuric acid and 54% sulfuric acid (Hawley)). Solution is a straw-colored oily liquid with a sharp odor. When pure, a crystalline solid decomposing at 73°C. Very irritating to skin and eyes. Used to make dyes and other chemicals.
Reactivity Profile Nitrosylsulfuric acid is an oxidizing agent. Neutralizes chemical bases in exothermic reactions. An attempt to diazotize dinitroaniline using Nitrosylsulfuric acid resulted in an explosion with loss of life. The event was blamed on the high concentration of the reactants dinitroaniline hydrochloride and Nitrosylsulfuric acid [MCA Case History 1763. 1971].
Health Hazard TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
