Reaction Steps
One suitable technique for preparing hydroxylamine sulfate is the classical Raschig process, described in Kirk-Othmer, Vol. 7 (1951), page 766, paragraph 4, Briefly, the classical Raschig process involves the reduction of sodium nitrite with sodium bisulfite and sulfur dioxide to give sodium hydroxylamine -N, N-disulfonate, followed by hydrolysis of the hot solution to give hydroxylammonium acid sulfate.
