A laboratory method is to mix solutions of sodium nitromethane, CH 2: NO(ONa), and mercuric chloride, a yellow basic salt being formed at the same time.

Pepper, Dingler's Jour., 1863, 167, p. 39): 2Zn0-1-4NaN03= 2Zn(ONa) 2 +2N 2 +50 2; by the use of cuprous chloride which when mixed with clay and sand, moistened with water and heated in a current of air at 100-200° C. yields an oxychloride, which latter yields oxygen when heated to 400° C (A.
