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]
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 .
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.
[4] [2] In the context of lubrication, alkylated naphthalenes are considered Group V base oils by the American Petroleum Institute . [ 5 ] For 2020, demand for this class of base oil (that includes other types of Group V base oils) was estimated at 823,000 tonnes per year. [ 4 ]
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]
2,6-Diisopropylnaphthalene (2,6-DIPN) is an organic compound with the formula C 10 H 6 (i-Pr) 2 (where i-Pr = isopropyl). 2,6-DIPN is one of several isomers of diisopropylnaphthalene. It is a white or colorless solid.
2,4,6-Tris(dimethylaminomethyl)phenol is an aromatic organic chemical that has tertiary amine and phenolic hydroxyl functionality in the same molecule. [1] The formula is C 15 H 27 N 3 O and the CAS Registry Number is 90-72-2. It is REACH registered and the European Community Number is 202-013-9. [2] [3] [4]
