| Pentachlorophenol is used as an industrial wood preservative for utility poles, crossarms, fence posts, and other purposes (79%);for NaPCP (12%); and miscellaneous, including mill uses, consumer wood preserving formulations and herbicide intermediate (9%) (CMR, 1980). As a wood preservative, pentachlorophenol acts as both a fungicide and insecticide (Freiter, 1978). The miscellaneous mill uses primarily involve the application of pentachlorophenol as a slime reducer in paper and pulp milling and may constitute ?6% of the total annual consumption of pentachlorophenol (Crosby et al., 1981). Sodium pentachlorophenate (NaPCP) is also used as an antifungal and antibacterial agent (Freiter, 1978). Pentachlorophenol also is used as a general herbicide (Martin and Worthing, 1977). | Choudhury et al., 1986. Pentachlorophenol: Health and Environmental Effects Profile. | Link |
| Pentachlorobenzene can be produced commercially by catalytic chlorination of any tetrachlorobenzene or by heating trichloroethylene to 700° C. It is a white, crystalline, solid material at room temperature, has a pleasant aroma, and like other halogenated benzenes, is lipophilic and hydrophobic. It is insoluble in water and cold alcohol but is soluble in hot alcohol, benzene, ether, carbon tetrachloride, chloroform, and carbon disulfide (USEPA, 1980a). Pentachlorobenzene melts at 86° C and boils at 277°C at atmospheric pressure. Its specific gravity at 16.5° C is 1.8342 (Sittig, 1981; Sax, 1984). Pentachlorobenzene has been used primarily as a precursor in the synthesis of the fungicide pentachloronitrobenzene and as a flame retardant (USEPA, 1980b). | McDonald et al., 1986.
