		It is either lead antimonate or a similar pigment consisting of a mixture of zinc oxide with yellow colouring matter.
		Napthalene is a white solid hydrocarbon with a strong smell; is also called mothballs, moth flakes, white tar, and tar camphor.
		Napthol exists in two varieties, alpha and beta, which are the mono-hydroxy derivatives of napthalene.

		Apply a drop or two of Napthalene Bromide (supplied with the instrument) to the polished face of the Refracting Prism.
		Lay the polished face of the standard sample on the refracting prism surface, with the Napthalene bromide acting as a "glue" to ensure proper contact between the sample and the prism face.
		Adjust the dispersion, using the Dispersion Correction Knob, until a clear light/dark boundary is seen.

		Anyway, the napthalene would be a safer material to handle, but I don't know how much of it might leach into the soil and/or make it toxic.
		When put on soil, it is absorbed moderately and biodegrades, but may end in groundwater if the concentration is high enough (like a large spill, probably not from just a few mothballs laying on the ground).
		I would guess that the napthalene from the mothballs would probably biodegrade within a few days, but I think we should reserve this question for any chemists in our audience.

		Napthalene is well absorbed following oral, dermal or inhalation exposure; napthalene is very lipid soluble.
		This is the "double edged sword of naphthalene poisoning." Thus, reversal of napthalene poisoning may be slow and ugly.
		As onset of toxic effects is fast, you may see "remnants" of the mothballs when the child is induced to vomit, even though the absorption of the napthalene is rapid.

		The second type of mixture uses chemicals such as ammonium chloride, napthalene, or anthracene which are vaporized without decomposition.
		When using mixtures containing a hydrocarbon such as napthalene, care must be taken that the hot vapor does not catch fire when it hits the open air.
		Also volatile chemicals such as napthalene oe hexachloroethane can sublimate from these mixtures so they must be sealed airtight.

		Therefore, it would be obvious to one skilled in the art that the photoactive compound, without the novolak resin and solvents, could be mixed with the polyimide in an alternate embodiment.
		Preferably, the photoactive compound is a 2-diazo-1 oxo napthalene, or a 1-diazo-2 oxo napthalene, which may contain a sulfonic acid group or an ester of sulfonic acid at the 4 or 5 positions on the napthalene ring.
		Generally, the diazo-oxo napthalenes are added to esterify an acid molecule.

		The vapour that is being produced is probably a derivative of napthalene - a benzene based aromatic compound used in moth balls, and coincidentally a solvent used by comic book restorers to remove tape residue and grease stains from comic books.
		The bad news is, napthalene's long term effects on lignin and ground wood pulp have not yet been determined.
		Another feasible reason for cedar's perseverance as a storage tool was the observation by collector's that comics stored within the box seemed to be as white as the day they were placed inside.

	OSCN Found Document:CHICKASHA COTTON OIL COMPANY v. HANCOCK
		They argue from this that any conclusion that they were responsible for the death of plaintiffs' cattle from chlorinated napthalene poisoning can only be based upon speculation, or upon an inference upon an inference, rather than upon facts necessary to establish causal connection.
		It was not possible to obtain an analysis of the particular pellets manufactured by defendants, and purchased by plaintiffs, for the evidence shows that by the time plaintiffs' cattle's ailment had been definitely diagnosed, all of said pellets had been consumed.
		The testimony indicated that the chlorinated napthalene from the grease vaporizes and is absorbed by the cotton seed meal covering the rollers.

		Mothball ingestion may be seen by the emergency physician in either an accidental setting - usually pediatric - or in the setting of substance abuse(1).
		Differentiation between the two types of mothballs is difficult because they have similar odors and are both white, crystalline solids at room temperatures.
		The differentiation, however, is important since napthalene has the potential to be quite toxic whereas PDB has a low order of toxicity and is generally considered non-toxic in the setting of an acute exposure.

		To do this, you will first determine the boiling point of the solvent and then the boiling points of two, different solutions of napthalene.
		You will have to weigh the napthalene and either weigh the solvent or measure its volume.
		You should note that all of the solvents are volitile and that their boiling points depend upon atmospheric pressure.

		Wester's II New Riverside Dictionary doesn't list napthalene (a word in common usage when I grew up), but it does list "moth balls" and suggests that they are made of camphor.
		Webster's is about the most useless dictionary I have around (they flood the market with their little book and make it cheap enough so that they are found everywhere (unfortunately)).
		As to dictionaries, nothing, but nothing, beats the O.E.D. What this all means is the the moth balls have dissolved themselves into the plastic parts of your car's interior, including the rubber backing of your carpet and right into the seats' spongy interior.
