Description and Uses
The chlorinated naphthalenes in which one ormore hydrogen atoms have been replaced by chlorine toform wax-like substances, beginning with monochloronaphthalene and going on to the octachlor derivatives.Their physical states vary from mobile liquids to waxysolids depending on the degree of chlorination; Freezing/Melting points of the pure compounds range from 17℃for 1-chloronaphthalene to 198℃for 1,2,3,4-tetrachloronaphthalene.1-chloro-isomer: Hazard Identification (based on NFPA704 M Rating System): Health 2, Flammability 1,Reactivity 02-chloro-isomer: Molecular weight=162.62; Boilingpoint=256℃; Freezing/Melting point=61℃.

1-Chloronaphthalene was widely used in Xylamits as a wood preservative with fungicidal and insecticidal properties in the past in Poland. 2-Chloronaphthalene was produced and used as a solvent in Poland, some of PCNs were found in polychlorinated biphenyls (PCBs) congeners.
