Industrial Agents Chemicals manufactured for industrial purposes rather than to specifically kill or maim human beings. Hydrogen cyanide, cyanogen chloride, phosgene, and chloropicrin are industrial chemicals that can be military agents as well AC, CK, CG, and PS. Many herbicides and pesticides are industrial chemicals that also can be chemical agents.

Chloropicrin (PS)—trichloronitromethane, CCl3N02 Green Cross, Klop—Is a colorless, volatile, slightly oily liquid with an Intense odor (see Table 4-1). It is very slightly soluble in water, soluble in ether, and miscible with benzene, absolute alcohol, and carbon disulfide.10It boils at about 112°C. 

Chloropicrin is also known as Klop (Germany), Aquinite (France), and PS (America). 

CS and CN are by far the most important irritants described above. CN was the primary pulmonary irritant after World War I until CS was developed in 1928. CS has replaced CN as the principal military and law enforcement RCA, while CN as Mace is available over the counter for personal protection in some places. Capsaicin as pepper spray has somewhat replaced CN as a personal protective agent. Other chemicals in this class that are worthy of mention are chloropicrin (PS) and bromobenzenecy-anide (CA). PS and CA were developed before World War I, but have largely have been replaced because... 

Physical Properties Chloropicrin is a colorless oil, bp of 112°C, and mp of 69°C, with apungent, stinging odor that has been described as anise-like. Its vapor pressure is approximately 20 mm/Hg at 20°C, and its molecular mass is 164 (Redeman et al., 1948). This liquid has a density of 1.66 g/mL and a vapor density of 5.6 relative to that of air. PS has low solubility in water (approximately 2 g/L), but is quite soluble in typical organic solvents (chloroform, acetone, ethyl acetate, etc.). Chloropicrin dissolves a variety of organic compounds including, for example, benzoic acid and various resins. 

Although chloropicrin is nonflammable, contact with oxidizing agents may lead to fires or explosions. High temperatures can produce toxic gases, including phosgene and carbon monoxide, from PS. 

Chloropicrin does not decompose rapidly in either cold water or cold mineral acids (e.g., hydrochloric acid), is stable in cold, dilute aqueous sodium hydroxide, but slowly decomposes in ethanolic potassium hydroxide. It undergoes more rapid decomposition with sodium ethoxide or ethanolic sodium cyanide. As with many other highly chlorinated organics, PS s stability is decreased in the presence of light as evidenced by color formation in solutions in benzene. Solutions of PS in acetone decompose slowly and deposit ammonium chloride. 

Studies of the mass spectmm of PS exist (Murty et al., 2005). The vibrational spectra of bromo-and chloropicrin have been analyzed (Mason et al., 1959), and electron diffraction studies of chloropicrin have been reported (Knudsen et al., 1966). 

Klop acquinite PS NC, Larvacide 100 Pic-fume. Russians used it in hand grenades in 1916 dissolved the chloropicrin in sulphuryl chloride (50%). Insecticide, fungicide, used to kill rats in ships. Oily liquid, yellowish in impure form, intense odour bp 112°C, attacks lead energetically, attacks iron and copper more slowly. Absorbed well by activated charcoal. Strong irritant and toxic asphyxiant.
