Naftalan or Naphtalan is a type of crude oil.It is named after Naftalan, Azerbaijan, where it is found.It is known for its use in alternative medicine.. Naftalan crude oil is too heavy for normal export uses (unlike Azerbaijan's plentiful Caspian Sea oil): it contains about 50 percent cycloalkanes (naphthenic hydrocarbons).

A practical synthesis involves the tin/HCl-reduction of the naphthalene-1-sulfonyl chloride. [1] 1-Naphthalenethiol can also be prepared from 1-bromonaphthalene by Pd-catalyzed reaction with the silylthiolate i Pr 3 SiSK followed by hydrolysis of the silathioether. [2] It was first prepared from the Grignard reagent generated from 1 ...
Naphthalene's minimum odor threshold is 0.084 ppm for humans. [44] Mothballs and other products containing naphthalene have been banned within the EU since 2008. [45] [46] In China, the use of naphthalene in mothballs is forbidden. [47] Danger to human health and the common use of natural camphor are cited as reasons for the ban.

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 +. [1]
1-Naphthol is used in each of the following chemical tests, which predate the use of spectroscopic and chromatographic methods: Molisch's test gives a red- or purple-colored compound to indicate the presence of carbohydrate. rapid furfural test turns purple quickly (<30s) if fructose is present, distinguishing it from glucose.
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.
