Concentrated H2SO4 from amidosulfonic acid?
According to wiki: "Sulfamic acid melts at 205 °C before decomposing at higher temperatures to H2O, SO3, SO2, and N2."
That seems pretty convenient. H2SO4, N2, SO2, and suppose a small amount of sulfurous acid.
But what would be the specifics of that reaction; how long would it take at "higher temperatures" and autogenous pressure to form a reasonable
quantity?
