Application: | 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. |
Application: | Powerful reducing agent. Converts aldehydes and ketones to oximes, and acid chlorides to hydroxamic acids. Used as catalyst, swelling agent, and copolymerization inhibitor in polymerization processes. |
General description: | Cyclohexanone oxime undergoes hydrolytic reaction with sulfuric acid to yield hydroxylamine sulfate. It reacts with sulfur dioxide to afford sulfamic acid. |
