Naphthalene is used mainly as a precursor to derivative chemicals. The single largest use of naphthalene is the industrial production of phthalic anhydride , although more phthalic anhydride is made from o -xylene .
Its ammonium derivative has a pK a of 12.7. The compound 1,8-bis(dimethylboryl)naphthalene is known as hydride sponge because of its high affinity for hydride. It solubilizes potassium hydride. Other distinctive compounds include the diphosphine 1,8-bis(diphenylphosphino)naphthalene (dppn) and the disulfide, both of which are ligand precursors.
Tetralin (1,2,3,4-tetrahydronaphthalene) is a hydrocarbon having the chemical formula C 10 H 12. It is a partially hydrogenated derivative of naphthalene. It is a colorless liquid that is used as a hydrogen-donor solvent. [2]
2-Naphthoic acid. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). 2-Naphthoic acid is an organic compound of the formula C 10 H 7 CO 2 H. It is one of two isomeric carboxylic acid derivatives of naphthalene, the other one being 1-naphthoic acid. It can be prepared by ...
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.
Naphthalenesulfonate. Naphthalenesulfonates are derivatives of sulfonic acid which contain a naphthalene functional unit. A related family of compounds are the aminonaphthalenesulfonic acids. Of commercial importance are the alkylnaphthalene sulfonates, which are used as superplasticizers in concrete. They are produced on a large scale by ...
substitution. Main arene substitution patterns. In ortho-substitution, two substituents occupy positions next to each other, which may be numbered 1 and 2. In the diagram, these positions are marked R and ortho. In meta-substitution the substituents occupy positions 1 and 3 (corresponding to R and meta in the diagram).
Unsymmetrical derivatives, i.e. those derived from two different amines, are obtained by hydrolysis of one of the two anhydride groups prior to the condensation with the first amine. These diimides are members of a broader class of compounds called rylenes, oligomers of naphthalene with bonds between the 1 and 1' and 8 and 8' positions. The ...
