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.
Most PAHs, like naphthalene, anthracene, and coronene, are planar. This geometry is a consequence of the fact that the σ-bonds that result from the merger of sp 2 hybrid orbitals of adjacent carbons lie on the same plane as the carbon atom. Those compounds are achiral, since the plane of the molecule is a symmetry plane.
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, or α-naphthol, is a 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 precursors ...
2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH).. On February 22, 2014, NASA announced a greatly upgraded database [1] [2] for detecting and monitoring PAHs, including 2-methylnaphthalene, in the universe.
2,6-Dimethylnaphthalene is mainly used for the preparation of 2,6-naphthalenedicarboxylic acid by oxidation of 2,6-dimethylnaphthalene in the liquid phase. 2,6-Naphthalenedicarboxylic acid is a monomer for the production of high-performance polymers, in particular poly (ethylene-2,6-naphthalene dicarboxylate) or shorter polyethylene naphthalate (PEN).

1-Naphthoic acid is an organic compound with the formula C 10 H 7 CO 2 H. It is one of two isomeric monocarboxylic acids of naphthalene, the other one being 2-naphthoic acid. In general the hydroxynaphthoic acids are more widely used than the parent naphthoic acids.
Chemical formula. C 14 H 6 N 2 O 4: Molar mass: ... NTCDI is produced from the parent naphthalene via an intermediate compound naphthalenetetracarboxylic dianhydride.
