It was first prepared by Robert Evert and Victor Merz in 1876 by hydrolysis of 2,6-dicyanonaphthalene. [2] [3] 1,8-Naphthalenedicarboxylic acid can be isomerized to 2,6-naphthalenedicarboxylic acid via the intermediacy of the dipotassium dicarboxylates. [2] It is also produced by oxidation of 2,6-diisopropylnaphthalene. [4]
1,5-Dihydroxynaphthalene is an organic compound with the formula C 10 H 6 (OH) 2. It is one of several isomers of dihydroxynaphthalene. A white solid, degraded samples often appear grey to light brown solid [1] that are soluble in polar organic solvents. It is a precursor to certain dyes.
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 .
The resulting materials have rigidly planar, highly conjugated cores. They exhibit good processing characteristics for fabrication of soft electronic devices. Aside from the NDIs, other members include the diimide derivatives of perylene-3,4:9,10-tetracarboxylic dianhydride and terrylene-3,4:11,12-tetracarboxylic dianhydride. [4]
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). [4]
Rishitin is a terpenoid compound, produced by some plants belonging to the Solanum family, including the potato [1] and tomato. [2] Rishitin belongs to a heterogeneous group of anti-microbial plant defense compounds termed phytoalexins and is produced upon pathogen attack. [3]
Diazanaphthalenes are a class of aromatic heterocyclic chemical compounds that have the formula C 8 H 6 N 2. They consist of a naphthalene double ring in which two of the carbon atoms have been replaced with nitrogen atoms. There are ten positional isomers, which differ by the locations of the nitrogen atoms. The group consist of two subgroups:
1,1,6-Trimethyl-1,2-dihydronaphthalene (TDN) is an aroma compound present in wine, [1] particularly aged Rieslings. [ 2 ] [ 3 ] Chemically, it is classified as a 13C-norisoprenoid, as it has thirteen carbon atoms, and is derived from an isoprenoid by the loss of methylene groups.
