Hydroxylamine from HNO3 and SnCl2?
« on: April 13, 2004, 03:32:00 AM »
Why is there no mention to the synthesis of hydroxylamine from nitric acid and Sn/HCl reduction on rhodiums or anywhere here. It sure seems a hell of a lot more OTC and even easier than finding nitrite and barium salts.

Does anybody know the specifics for this reaction? The book only gives the rough outline.

Rhodium, or anybody else chemically enclined... What is the ideal ratio of SnCl2 to nitric acid? And how much excess hcl should be present for the formation of the hydrochloride? Could someone help me draw up some experimental procedures for me to mess with and see what happens? A more detailed or proven proceudre would be nice if anbody knows of one in some inorg. book.


It basically jsut says, Sn+2HCl-> SnCl2+H2, this is combined with dilute nitric acid, and a considerable ammount of it is reduced to hydroxylamine. Excess acid gives NH4OCl and NH4Cl. Addition of H2S and subsequent stannous sulphide filtered, evaporated to dryness, NH4OCl extracted from residue with alcohol, and this in turn evaped to give white crystaline solid.
