| 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more hydrogen atoms have been replaced by chlorine to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.

| Questions And Answer | Back Directory | [Synthesis]
Polychlorinated naphthalene was prepared from naphthalene and phosphorus pentachloride as starting materials via a substitution reaction (Williamson reaction). All reagents used in the experiment were commercially available. The synthesis experiment using phosphorus pentachloride as the chlorinating agent was carried out in a pressure-resistant stainless steel reactor lined with polytetrafluoroethylene (PTFE). Experimental procedure: Naphthalene and phosphorus pentachloride were weighed and added to the PTFE-lined reactor, which was then sealed in a pressure-resistant stainless steel reactor and reacted at 260°C for 15 hours. After the reaction, the PTFE-lined reactor was removed and poured into ice water to remove unreacted PCI5. The insoluble solid was collected, washed with a small amount of water, dissolved in a small amount of toluene, dried with anhydrous MgSO4, filtered, and then an equal volume of anhydrous ethanol was added. The mixture was heated to reflux, filtered while hot, and then cooled to crystallize, yielding perchloronaphthalene. Mass spectrometry characterization was performed (spectrum shown below), with an average yield of 85%.

Insoluble in water. | [Potential Exposure]
Industrial exposure from individual
chlorinated naphthalenes is rarely encountered; rather it
usually occurs from mixtures of two or more Chlorinated
naphthalenes. Due to their stability, thermoplasticity, and
nonflammability, these compounds enjoy wide industrial
application. These compounds are used in the production of
electric condensers; in the insulation of electric cables and
wires; as additives to extreme pressure lubricants; as supports for storage batteries; and as a coating in foundry use.
octachloro-: Used as a fireproof and waterproof additive
and lubricant additive. Pentachloro-: Used in electric wire
insulation and in additives to special lubricants. tetrachloro-: Used in electrical insulating materials and as an
additive in cutting oils. trichloro-: Used in lubricants and
in the manufacture of insulation for electrical wire.
Because of the possible potentiation of the toxicity of higher Chlorinated naphthalenes by ethanol and carbon tetrachloride, individuals who ingest enough alcohol to result in
liver dysfunction would be a special group at risk.
Individuals, e.g., analytical and synthetic chemists, mechanics and cleaners, who are routinely exposed to carbon tetrachloride or other hepatotoxic chemicals would also be at a
greater risk than a population without such exposure.
Individuals involved in the manufacture, utilization, or disposal of polychlorinated naphthalenes would be expected to
have higher levels of exposure than the general population. | [Fire Hazard]
Literature sources indicate that this chemical is nonflammable. | [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]

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

Chemical research; organic synthesis. According to HSDB (1005), U.S. has discontinued
manufacturing of chlorinated naphthalenes since 1977. Chlorinated naphthalenes were formerly
used as a wood preservative, additives in cutting oils, and as an additive in fireproofing and
waterproofing cable insulation. | [Uses]
In electric cable insulation; additive to
lubricants | [Uses]
