[citation needed] Approximately 1.3 million tons are produced annually. [citation needed] Naphthalene is the most abundant single component of coal tar. [citation needed] The composition of coal tar varies with coal type and processing, but typical coal tar is about 10% naphthalene by weight.
Naphthalene is a major component of some mothballs.It repels moths as well as some animals. [citation needed]Since mothballs that contain naphthalene are considered hazards, safer alternatives have been developed, such as the use of 1,4-dichlorobenzene, however, 1,4-dichlorobenzene has been declared as a potential neurotoxin. 1,4-dichlorobenzene has been linked to potentially causing ...
For paraffinic base oils, pour points are usually between −12 °C and −15 °C, and are determined by operation of the dewaxing unit. The pour points of naphthenic base oils, generally devoid of wax content, may be much lower (down to <−70 °C). [10]
The naphthalene route (the Gibbs phthalic anhydride process or the Gibbs–Wohl naphthalene oxidation reaction) has declined relative to the o-xylene route. Proposed early steps in vanadium -catalyzed oxidation of naphthalene to phthalic anhydride, with V 2 O 5 represented as a molecule versus its true extended structure.

The required dose for a rate of 50 percent lethality is 70 mg-min/m 3. [17] VX is also another nerve agent like GB but is much more lethal. At the non-disabling and disabling levels, VX causes the same effects as GB but at much lower doses, 12 times less than that of GB. Also, a mere 30 mg-min/m 3 will give a death rate of 50 percent.
