METHOD OF TRINITROTOLUENE DESTRUCTION Russian patent published in 2015 - IPC B01J8/00 B01J19/10 A62D3/00 C07C205/06 

FIELD: chemistry.

SUBSTANCE: invention relates to field of chemical technology of energy-saturated materials, namely to methods of utilisation of formed wastes of production of defective and expired products, and is intended for laboratory methods of trinitrotoluene decomposition. Method of trinitrotoluene destruction consists in influencing trinitrotoluene in water medium with alkaline chemical reagents - water solutions of sodium sulphite and sodium hydroxide with concentration 5-20%, with weight ratio trinitrotoluene: chemical reagent, equal 1:3-30, and simultaneous impact with ultrasonic fluctuations with frequency not lower than 20 kHz and intensity not lower than 2,5 W/cm²; and at initial temperature 40-50°C heating is realised due to absorption of energy of ultrasonic fluctuations to temperature 80-85°C.

EFFECT: invention provides complete decomposition of explosive substance, absence of toxic organic products and high rate of the process.
