	CHEC Chemical Profile: 1,4-dichlorobenzene
		Paradichlorobenzene is a white solid in the halogenated organic class of chemicals.
		Paradichlorobenzene is also used to manufacture plastics and other industrial chemicals.
		Paradichlorobenzene smells similar to mothballs and is the sweet odor often encountered in public restrooms.

		However, once the paradichlorobenzene has resolidified the test tubes may be stopped and stored for use in the same lab experiment next year.
		Paradichlorobenzene is a white, solid crystal with a wet, oily surface.
		Paradichlorobenzene is commonly found in mothballs, moth crystals, and in diaper, toilet, and room deodorizers.

	INFORM - Fact Sheet - Purchasing for Pollution Prevention: Fact Sheet on Respiratory Hazards and Restroom Deodorant ...
		Some restroom and urinal deodorant blocks contain paradichlorobenzene (p-dichlorobenzene, 1,4-dichlorobenzene, or "para"), a respiratory irritant that can trigger an asthma attack in someone who already has asthma.
		Most of our exposure to paradichlorobenzene occurs indoors, with the source being products such as deodorant blocks and mothballs.
		Many restroom and urinal deodorizing blocks that do not contain paradichlorobenzene do contain ammonium quaternary compounds ("quats"), disinfectants that are known to cause asthma when used in cleaners.

	PRODUCT MATRIX - Paradichlorobenzene
		Paradichlorobenzene is a white solid crystal with a wet oily surface.
		Paradichlorobenzene is commonly found in mothballs, moth crystals, and in diaper, toilet, and room deodorizers.
		The lack of convincing reports of human and animal toxicity supports the notion that paradichlorobenzene has a lower order of acute toxicity than naphthalene, which is also commonly used as a moth repellent.

	Pesticides \| An Introduction to Indoor Air Quality \| Indoor Air \| Air \| US EPA
		One pesticide often found in the home is paradichlorobenzene, a commonly used active ingredient in moth repellents.
		Where possible, paradichlorobenzene, and items to be protected against moths, should be placed in trunks or other containers that can be stored in areas that are separately ventilated from the home, such as attics and detached garages.
		Paradichlorobenzene is also the key active ingredient in many air fresheners (in fact, some labels for moth repellents recommend that these same products be used as air fresheners or deodorants).

	Mothball Abuse Comes Out of the Closet
		Some teenagers are using mothballs to get high, a trend that may be underreported, researchers say.
		Reuters reported July 27 that users place mothballs, which contain paradichlorobenzene, in a bag and inhale from it for about 10 minutes.
		Paradichlorobenzene, also found in air fresheners and insect repellents, can cause anemia and liver and kidney failure.

	Toilet/Urinal Deodorizers Containing Paradichlorobenzene (Site not responding. Last check: )
		Specifically, no board of education, principal or other person in charge of any public or private, elementary or secondary school shall authorize the purchase of or purchase any urinal or toilet deodorizer containing paradichlorobenzene.
		In addition, no public or private, elementary or secondary school may use or authorize the use of toilet or urinal deodorizers containing paradichlorobenzene in any toilet or urinal in any school building or any other facility under the control of the school.
		According to the Department of Environmental Conservation’s Division of Solid and Hazardous Waste, since schools can longer use toilet and urinal deodorizers containing paradichlorobenzene they may either: (1) give the product away to someone who can legally use the product, or (2) dispose of the product as hazardous waste under regulatory requirements found at: http://www.dec.state.ny.us/website/regs/part371a.html.

	PROPERTIES OF MATTER
		The amounts of materials and equipment used will depend on whether the experiment is performed individually or in groups by the class or whether the instructor demonstrates the experiment for the class.
		Sodium chloride and paradichlorobenzene are chosen as the typical solids because they are usually readily available and inexpensive for high school use.
		Additional typical ionic and covalent solids may be added to or substituted for these two substances depending on the purposes of the instructor.

	Product Report - Pest Control—Moths
		In some cases, infants born to mothers exposed to naphthalene during pregnancy have been found to have hemolytic anemia, indicating that the substance may damage fetuses in the womb.
		Individuals exposed to paradichlorobenzene, the other common ingredient in mothballs, may experience skin, throat, and eye irritation.
		Long-term exposure to paradichlorobenzene can damage the central nervous system, as well as the liver and the skin.

	Agrochemicals - herbicides, insecticides, fungicides, plant growth regulators
		Fumigants, which may initially have the form of a solid, liquid, or gas, kill pests while in a gaseous state.
		For example, paradichlorobenzene, used against moths, comes as a solid cake that vaporizes when exposed to air.
		Some insecticides and fungicides are systemic, i.e., they are translocated by a plant from the area of application to other plant parts, where they affect only pests that feed on the crop.

	Paradichlorobenzene Properties
		BOILING POINT ELEVATION: The general equation for boiling point elevation is similar, except for a sign change: -ln(Xa)=(Hv/R)(1/Tb - 1/T) where Xa is the mole fraction of paradichlorobenzene, Hv is the heat of vaporization, and Tb = boiling point of pure paradichlorobenzene*.
		DATA: All temperatures are expressed in Kelvin: Hf = 2064 cal/mol, Tf = 326.28 Hv = 17260.5 cal/mol, Tb=447.35 MANIPULATION: Assuming T is measured then all terms on the right hand side of the equations above are known and Xa can be calculated.
		Xa = Na/(Na + Nb) where Na and Nb are the number of moles of paradichlorobenzene and solute respectively.
