Tetryl is hydrolyzed rapidly by boiling aqueous sodium carbonate
to form sodium picrate, sodium nitrite, and methylamine
which escapes. It is not affected by prolonged boiling with dilute
sulfuric acid. It reacts with aniline in benzene solution at ordinary
temperature; red crystals of 2,4,6-trinitrodiphenylamine,
m p. 179.5-180°, separate after the liquid has stood for a few
hours, and extraction of the liquid with water yields an aqueous
solution of methylnitramine.
