HALOWAX 1013

Chemical Properties

Pentachloronaphthalene is a pale yellow or white solid powder with an aromatic odor.

Chemical Properties

The chlorinated naphthalenes in which one or more hydrogen atoms have been replaced by chlorine to form wax-like substances, beginning with monochloronaphthalene and going on to the octachlor derivatives.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:

Uses

In electric wire insulation; in lubricants

General Description

Pale-yellow to white solid or powder with an aromatic odor. Bp: 327-371°C; mp: 120°C. Density 1.7 g cm-3. Used in lubricants and in the manufacture of insulation for electrical wire. Presents an environmental danger. If released into the environment, bioaccumulation takes place, specifically in fish. Will persist in the environment causing long-term adverse effects. The halowaxes are technical-grade chlorinated naphthalenes containing HALOWAX 1013 in its various isomers together with (mainly) trichloro- tetrachloro- and hexa-chloronapthalenes in their various isomers.

Reactivity Profile

HALOWAX 1013 is non-flammable, but combustible. Gives off irritating or toxic gases in a fire. Incompatible with strong oxidizing agents. Reacts violently with aluminum, with bases, and with liquid O2.

Health Hazard

Pentachloronaphthalene is toxic to the liver and skin.

Safety Profile

Poison by ingestion, inhalation, and skin contact. An irritant. Action similar to that of chlorinated naphthalenes and chlorinated diphenyls. Dangerous; when heated to decomposition it emits highly toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, AROMATIC

Potential Exposure

Used in electric wire insulation, in additives to specialized lubricants; and as a fire-and waterproofing agent. No longer produced or used in the US.

Shipping

UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Violent reaction with strong oxidizers, aluminum, liquid oxygen; potassium, sodium. Heat may contributes to instability.

Waste Disposal

High-temperature incineration with flue gas scrubbing. Incineration, preferably after mixing with another combustible fuel. Care must be exercised to assure complete combustion to prevent the formation of phosgene. An acid scrubber is necessary to remove the halo acids produced.
