Reactivities / Incompatibilities

Mustard-Lewisite Mixture is rapidly corrosive to brass at 65 deg C and will corrode steel at a rate of 0.0001 inches of steel per month at 65 deg C. It will hydrolyze into hydrochloric acid, thiodiglycol, and non-vesicant arsenic compounds.
Hydrolyses rapidly in water and in acidic medium to form HCl and non-volatile (solid) chlorovinylarsenious oxide. Hydrolysis in alkaline medium (e.g., alcoholic caustic, carbonate solution or DS2) produces acetylene and trisodium arsenate (Na3As04) in solution containing toxic arsenic.
Decomposed by water and alkalies.
