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]
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]
Syringol is the organic compound with the formula HO(CH 3 O) 2 C 6 H 3. The molecule is a phenol, with methoxy groups in the flanking (2 and 6) positions. It is the symmetrically dimethylated derivative of pyrogallol. It is a colorless solid, although typical samples are brown owing to air-oxidized impurities.
DMMDA-3 could be made from exalatacin (1-allyl-2,6-dimethoxy-3,4-methylenedioxybenzene). Exalatacin can be found in the essential oil of both Crowea exalata and Crowea angustifolia var. angustifolia. [6] In other words, exalatacin is an isomer of both apiole and dillapiole, which can be used to make
A solution of lithium naphthalenide, the lithium salt of naphthalene, in tetrahydrofuran. The alkali metal naphthalene salts are prepared by stirring the metal with naphthalene in an ethereal solvent, usually as tetrahydrofuran or dimethoxyethane. The resulting salt is dark green. [2] [3] [4] The anion is a radical, giving a strong EPR signal ...
Diaminonaphthalene describes several isomers containing naphthalene substituted with two amine groups (NH 2), also called naphthalenediamines. All isomers are white solids that tend to air-oxidize. The 2,3-, 1,5-, and 1,8- derivatives have attracted most attention. 1,2-Diaminonaphthalene 938-25-0 [1] 1,3-Diaminonaphthalene 24824-28-0 [2]
DMCM (methyl 6,7-dimethoxy-4-ethyl-β-carboline-3-carboxylate) is a drug from the β-carboline family that induces anxiety and convulsions by acting as a negative allosteric modulator of GABA A receptors — functionally opposite to benzodiazepines and related drugs which are positive allosteric modulators — and is used in scientific research for these properties to test new anxiolytic and ...
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 .
