8. It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. [15] As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings. It is the main ingredient of traditional mothballs.
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 ...
Sodium naphthalene is an organic salt with the chemical formula Na +[C 10 H 8]−. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na+.
Older mothballs consisted primarily of naphthalene, but due to naphthalene's flammability, many modern mothball formulations instead use 1,4-dichlorobenzene.The latter formulation may be somewhat less flammable, although both chemicals have the same NFPA 704 rating for flammability.
1-Methylnaphthalene defines the lower (zero) reference point of cetane number, a measure of diesel fuel ignition quality, as it has a long ignition delay (poor ignition qualities). In contrast, cetane, with its short ignition delay, defines the upper reference point at 100. [2] In testing, isocetane (2,2,4,4,6,8,8-heptamethylnonane or HMN ...
Cycloalkane. Ball-and-stick model of cyclobutane. In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. [1] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains), and ...
Naphtha. Naphtha (/ ˈnæpθə / or / ˈnæfθə /) is a flammable liquid hydrocarbon mixture. Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat. In some industries and regions, the name naphtha refers to crude oil or ...
Alkylated naphthalene. Alkylated naphthalenes are chemical compounds made by the alkylation of naphthalene or its derivatives with an olefin. These compounds are used as synthetic base oils, and are claimed to have improved oxidative stability over some conventional base oils. [1][2][3] Having an aromatic core, alkylated naphthalenes are better ...
