Chemical Properties

Appearance The chlorinated naphthalenes in which one or more hydrogen atoms have been replaced by chlorine to form wax-like substances, beginning with monochloronaphthalene and going on to the octachlor derivatives.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 17C for 1-chloronaphthalene to 198C for 1,2,3,4- tetrachloronaphthalene. 1-Chloro-isomer: Hazard identification (based on NFPA-704 M Rating System): Health 2, flammability 1, reactivity 0. 2-Chloro-isomer:
Melting point  92.8°C
Boiling point  301.08°C (rough estimate)
density  1.5800
refractive index  1.6030 (estimate)
CAS DataBase Reference 1321-65-9
