Naphthalene is an organic compound with formula C 10 H 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.
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]
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.
1,8-Bis(dimethylamino)naphthalene is an organic compound with the formula C 10 H 6 (NMe 2) 2 (Me = methyl). It is classified as a peri-naphthalene , i.e. a 1,8-disubstituted derivative of naphthalene .
N-(1-Naphthyl)ethylenediamine dihydrochloride is widely used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound .
1-Naphthol, or α-naphthol, is an organic compound with the formula C 10 H 7 OH. It is a fluorescent white solid. 1-Naphthol differs from its isomer 2-naphthol by the location of the hydroxyl group on the naphthalene ring. The naphthols are naphthalene homologues of phenol. Both isomers are soluble in simple organic solvents. They are ...
Acenaphthene was prepared for the first time in 1866 [4] by Marcellin Berthelot by reacting hot napthalene vapours with acetylene, and a year later he reproduced a similar reaction with ethylene as well as discovered acenaphthene in coal tar. [5] Later Berthelot and Bardy synthesized the compound by cyclization of α-ethylnaphthalene.
Chemical structure of 12-phthaloperinone, a derivative of 1,8-diaminonaphthalene. It is prepared by reduction of 1,8-dinitronaphthalene, which in turn is obtained as a mixture of isomers by nitration of 1-nitronaphthalene. Upon treatment with phthalic anhydride derivatives, the diamine converts to phthaloperinones. [2]
