Properties: Canary-yellow crystals from carbon tetrachloride. Poisonous. Dimorphous. The stable form occurs as orthorhombic crystals; d 1.65; mp 195°; bp 410° (decompn). Sublimes readily. Vapor press. at 20° = 2 ´ 10-13 mm; volatility 0.02 mg/cu m; heat of volatilization 54.8 cal; spec heat 0.268 cal. Practically insol in water. Slightly sol in benzene, xylene, carbon tetrachloride. Corrodes iron, bronze, brass. (The metastable form melts at 186° if monoclinic, and at 182° if triclinic.)
Melting point: mp 195°
Boiling point: bp 410° (decompn)
Density: d 1.65
CAUTION: Irritating to skin and respiratory tract. Causes profuse watery nasal discharge; severe pain in nose, sinuses, chest; sneezing, coughing, nausea, vomiting, marked depression, weakness. Sensory disturbances may occur later.
Use: As war gas, dispersed in air in the form of minute particles. For riots in combination with tear gas (chloroacetophenone). In the formulation of wood-treating solns, against marine borers and similar pests.
