[1] [2] [3] Having an aromatic core, alkylated naphthalenes are better at solvating polar compounds than alkane mineral oils and polyalphaolefins. [ 4 ] [ 2 ] In the context of lubrication, alkylated naphthalenes are considered Group V base oils by the American Petroleum Institute . [ 5 ]
2-Methoxynaphthalene, also called β-naphthol methyl ether or yara yara, [2] is a stabilizer found in gunpowder, particularly smokeless gunpowders. It is soluble in alcohol , and insoluble in water and dipropylene glycol .
2-Naphthol, or β-naphthol, is a fluorescent colorless (or occasionally yellow) crystalline solid with the formula C 10 H 7 OH. It is an isomer of 1-naphthol, differing by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol, but more reactive.
2-Naphthalenethiol is an organosulfur compound with the formula C 10 H 7 SH. It is a white solid. It is a white solid. It is one of two mono thiols of naphthalene , the other being 1-naphthalenethiol .
Figure 1. Top) Thermal isomerization of azulene to naphthalene; Bottom) Thermal automerization of naphthalene. Thermal rearrangements of aromatic hydrocarbons are considered to be unimolecular reactions that directly involve the atoms of an aromatic ring structure and require no other reagent than heat.
A solution of lithium naphthalenide, the lithium salt of naphthalene, in tetrahydrofuran. The alkali metal naphthalene salts are prepared by stirring the metal with naphthalene in an ethereal solvent, usually as tetrahydrofuran or dimethoxyethane. The resulting salt is dark green. [2] [3] [4] The anion is a radical, giving a strong EPR signal ...
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 ...
2-Chloronaphthalene is obtained directly by chlorination of naphthalene, with the formation of more highly substituted derivatives such as dichloro- and trichloronaphthalenes, in addition to the two monochlorinated isomeric compounds: 1-chloronaphthalene and 2-chloronaphthalene. [4]
