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.
Aminonaphthalenesulfonic acids are compounds with the composition C 10 H 6 (NH 2)(SO 3 H), being derived from naphthalene (C 10 H 8) substituted by an amino and sulfonic acid groups. These compounds are colorless solids. They are useful precursors to dyes. [1]
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 ...
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
DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride) is an organic triazine derivative commonly used for activation of carboxylic acids, particularly for amide synthesis. Amide coupling is one of the most common reactions in organic chemistry and DMTMM is one reagent used for that reaction.
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 ...
