Descrizione generale

Cyclohexanone oxime undergoes hydrolytic reaction with sulfuric acid to yield hydroxylamine sulfate. It reacts with sulfur dioxide to afford sulfamic acid.

Applicazioni

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.
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.
