METHOD OF REPROCESSING REACTIVE MASSES PRODUCED DURING LEWISITE DETOXIFYING PROCESS Russian patent published in 2002 - IPC

Abstract RU 2192297 C1

FIELD: chemical technology. SUBSTANCE: method involves steaming reactive masses; settling arsenic in the form of oxide by successively adding hydrochloric and sulfuric acids. Optimal settling process conditions: hydrochloric acid is introduced in an amount required for obtaining final reaction acidity of 7; sulfuric acid is introduced in an amount required for obtaining final acidity of medium of 1-5; final stage of arsenic oxide settling process is conducted at temperature less than or equal to 25 C. Method allows arsenic oxide to be produced from reactive mass by simplified process chart. EFFECT: increased efficiency and simplified method. 3 cl
