Hydroxylamine-O-sulfonic acid Chemical Properties,Uses,Production

Chemical Properties

white to slightly beige crystalline powder

Purification Methods

Stir the solid vigorously with anhydrous Et2O and filter it off using large volumes of dry Et2O. Drain dry at the pump for 5minutes and then for 12-14hours in a vacuum. Store it in a vacuum desiccator over conc H2SO4. Determine the purity by oxidation of iodide to I2. It must be stored in a dry atmosphere at 0-4o. It decomposes slowly in H2O at 25o and more rapidly above this temperature. [Matsuguma & Andrieth Inorg Synth V 122 1957.]
