Abstract
A method of removing tetranitromethane from waste gases (e.g., from trinitrotoluene plants) by scrubbing the waste gases with a solution of (1) water, (2) hydrogen peroxide, and (3) an alkali metal hydroxide or alkali metal carbonate. Tetranitromethane is converted into trinitromethane or a soluble alkali metal salt of trinitromethane.
