Naphthalene is a crystalline, white hydrocarbon, with a strong smell. It is best known as the main ingredient in mothballs, urinal deodorizer blocks, and can be used as an antiseptic. In mothballs, it is used as an insecticide or pesticide. Naphthalene is toxic. In humans, being exposed to naphthalene can destroy red blood ein Reference: a) Naphthalene has C 2-rotational axis passing through the C9-C10 has two C 2-axes perpendicular to the principal C 2-rotational axis (one is passing through the mid-point of the C9-C10 bond another passing through the midpoints of C2-C3, C9-C10, C6-C7 bonds).It has one h-plane which is passing through the midpoints of C2-C3, C9-C10, C6-C7 bonds and 97%(37).

d(ln(k H))/d(1/T): Temperature dependence parameter for Henry's Law constant: k° H Henry's Law constant at K. Naphthalene is released to the air from the burning of coal and oil and from the use of mothballs.
Coal tar production, wood preserving, and other industries release small amounts. (1) Typical air concentrations of naphthalene in cities are about parts per billion (ppb). (1) Naphthalene has also been detected in tobacco smoke. (1). The reaction of naphthalene with potassium, performed by Berthelot almost years ago, was the first example of polyarene reduction.
36 Naphthalene can accept up to two electrons upon reduction with the formation of a radical monoanion or a diamagnetic dianion. 37 The association of naphthalene radical monoanions with alkali metal ions in. Naphthalene $ /pound. It is a white compound with a tar-like odor.
It often comes as plate-like crystals. Melts at 80 deg.C. and is insoluble in water. Main pyrotechnical use is for production of black smokes (similar to anthracene). In stock. Naphthalene quantity. Add to cart. Naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C 1 0 H is an important hydrocarbon raw material that gives rise to a host of substitution products used in the manufacture of dyestuffs and synthetic resins.
Naphthalene is the most abundant single. Naphthalene poisoning (or mothball poisoning) is a form of poisoning that occurs when naphthalene is ingested. Severe poisoning can result in haemolytic anaemia.
 Naphthalene was introduced in by Rossbach as an antiseptic to counteract typhoid gh naphthalene was widely used industrially, only 9 cases of poisoning were. Print book: National government publication: EnglishView all editions and formats: Rating: (not yet rated) 0 with reviews - Be the first.

(ANI/BusinessWire India): The 2nd edition of the book titled "Surfactants, Disinfectants, Cleaners, Toiletries, Personal Care Products Manufacturing and.
Intraperitoneal injections of the freshly made naphthalene solution described previously are performed at 10 μl/g body weight (i.e., μl for a 25‐g mouse given a total dose of mg/kg).
Naphthalene‐injured animals will present a ruffled appearance with crusted eyes at approximately 20–36 h postinjury. Naphthalene is a white solid that evaporates easily. It is also called mothballs, moth flakes, white tar, and tar camphor. When mixed with air, naphthalene vapors easily burn.
Fossil fuels, such as petroleum and coal, naturally contain naphthalene. Burning tobacco or wood produces naphthalene. The major products made from naphthalene are moth repellents, in the. Naphthalene is a white solid substance with a strong smell.
Poisoning from naphthalene destroys or changes red blood cells so they cannot carry oxygen. This can cause organ damage. This article is for information only.
DO NOT use it to treat or manage an actual poison exposure. If you or someone you are with has an exposure, call your local. naphthalene concentrations in personal air samples, indicating that naphthalene is absorbed in humans. The first step in the metabolism of naphthalene is the formation of naphthalene-1,2-oxide by cytochrome P in the presence of NADPH, which is converted to the trans-1,2-diol and other products.
The electrophilic naphthaleneFile Size: 3MB. Naphthalene is usually sold commercially according to its freezing or solidification point, because there is a correlation between the freezing-point and the naphthalene content of the product; the correlation depends on the type and relative amount of impurities that are present.
Because the freezing point is changed appreciably by the presence of water, values and specifications are. Naphthalene is a ubiquitous pollutant, and very high concentrations are sometimes encountered indoors when this chemical is used as a pest repellent or deodorant.
This study describes the distribution and sources of vapor phase naphthalene concentrations in four communities in southeast Michigan, by:. Interpretation: Is Naphthalene whether more soluble in ethanol or benzene has to be identified.
Concept Introduction: Solubility of any compound follows the rule – “Like dissolves like”. According to this rule we could say that polar compounds dissolve in polar solvents and non-polar compounds dissolve in non-polar solvents.In reality, naphthalene is the simplest of the aromatic hydrocarbons with more than one ring (the polycyclic hydrocarbons) – effectively it is two benzene rings stuck together – and is traditionally derived from coal tar, hence its name to suggest a naptha derivative.Naphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets.
It was used in preparation of carbon-coated Si 70 Sn 30 nanoparticles. It was used as fluorescent probe to study the aggregation behavior of sodium cholate.
