Application
强还原剂。可将醛和酮转化为肟，将酰基氯转化为氧肟酸。可用作聚合过程中的催化剂、溶胀剂和共聚反应抑制剂。
Hydroxylamine sulfate may be used in the following:
- Along with NaCl for reduction during the atomic absorption spectrophotometric quantification of mercury at ppb (parts-per-billion) levels in solution.
- As one of the constituents during the preparation of a coloring solution, impregnated in a cellulose based monitoring tape for the sensitive detection of formaldehyde gas.
- Simultaneous estimation of hydrarine and hydroxylamine in mixtures by titration with alkaline ferricyanide in presence of zinc sulfate.
General description
Cyclohexanone oxime undergoes hydrolytic reaction with sulfuric acid to yield hydroxylamine sulfate. It reacts with sulfur dioxide to afford sulfamic acid.
