| Chemical Properties | Back Directory | [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more hydrogen atoms have been replaced by chlorine to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.

| Hazard Information | Back Directory | [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. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical
attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. | [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. | [Chemical Properties]
Pentachloronaphthalene is a pale yellow or

2-Chloro-isomer: | [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. | [Uses]
In electric wire insulation; in lubricants | [Health Hazard]
Pentachloronaphthalene is toxic
to the liver and skin. |
