a colorless, thick, oily, flammable, highly explosive, slightly water-soluble liquid, C 3 H 5 N 3 O 9 , prepared from glycerol with nitric and sulfuric acids: used chiefly as a constituent of dynamite and other explosives, in rocket propellants, and in medicine as a vasodilator in the treatment of angina pectoris.
a pale yellow viscous explosive liquid substance made from glycerol and nitric and sulphuric acids and used in explosives, and in medicine as a vasodilator. Formula: CH2NO3CHNO3CH2NO3 Also called trinitroglycerine
