Chloraloxime, CC1 3 CH: NOH, is obtained when one molecular proportion of chloral hydrate is warmed with four molecular proportions of hydroxylamine hydrochloride and a little water.
Nascent hydrogen reduces it to hydroxylamine (q.v.), whilst solutions of hypochlorites oxidize it to nitric acid.
Pure anhydrous .hydroxylamine has been obtained by C. A.
Meyer, Ber., 1900, 33, p. 2580), and this latter compound condenses with hydroxylamine to form xanthone oxime.
