It was once manufactured in the U.S., Japan, and Germany[2] for use as a chemical weapon, acting as a vesicant (blister agent) and lung irritant. Although colorless and odorless, impure samples of lewisite are a yellow or brown liquid with a distinctive odor that has been described as similar to scented geraniums.[3] [edit] The compound is prepared by the addition of arsenic trichloride to acetylene in the presence of a suitable catalyst: AsCl3 + C2H2 → ClCHCHAsCl2 Lewisite, like other arsenous chlorides, hydrolyses in water to form hydrochloric acid: ClCHCHAsCl2 + 2 H2O → ClCHCHAs(OH)2 + 2 HCl This reaction is accelerated in alkaline solutions, with poisonous (but non-volatile) sodium arsenite being the coproduct. Mode of action as chemical weapon[edit] Arsenite inhibits important biochemical pathways of the human body. Chemical composition[edit] History[edit] Lewisite is named after the US chemist and soldier Winford Lee Lewis (1878–1943).
