Chemical Structure
Basic Info
With several applications, Pyridine-2,6-Dicarboxylic Acid is a crucial intermediate in pharmaceutical production. Bacterial spores naturally contain pyridine-2,6-dicarboxylic acid, but its low amount makes it difficult to extract and cannot meet demand. It is not suitable for use and manufacturing in industry. The first report on artificial synthesis was published in 1935 by ALVIN.W. Singer and S.M. McElvein of the University of Wisconsin, who oxidized 2,6-lutidine with a 64% yield using potassium permanganate in water as a solvent. It is often made in industry by oxidizing 2,6-lutidine.

Application 1. CN202010753097.9 discloses a vanadium pyridine catalyst for catalytic oxidation to prepare 2,5-dichlorophenol, and its synthesis method and application. The catalyst is a Py-V complex having the following structural formula, which is prepared by dissolving pyridine-2,6-dicarboxylic acid in methanol, adding acetylacetonato vanadyl, and then refluxing, filtering, washing, drying and other steps. The method has simple operation steps and is easy to control. The yield is more than 60% in terms of vanadium, and the entire synthesis process is short in time, which is suitable for industrial production. In the process of catalytic oxidation of 1,4-dichlorobenzene to prepare 2,5-dichlorophenol, the Py-V complex is used as a catalyst, which can effectively inhibit the over-oxidation of 2,5-dichlorophenol while improving the catalytic efficiency. The over-oxidation product can be controlled below 10%, and the selectivity of 2,5-dichlorophenol reaches more than 90%, and the oxidation reaction efficiency and yield are significantly improved.
Application 2, CN201811320241.9 specifically relates to a polyester resin for low-gloss TGIC system powder coating, and also relates to a method for preparing the above-mentioned polyester resin, and the application of the polyester resin. The polyester resin of the present invention mainly includes isophthalic acid, pyridine-2,6-dicarboxylic acid, 6-acetylaminocaproic acid, 3-hydroxy-4-aminobutyric acid, polyethylene glycol diglycidyl ether, neopentyl glycol, 2,4,6-trihydroxybenzoic acid, N-hydroxyethylethylenediaminetriacetic acid, esterification reaction catalyst, and antioxidant. The polyester resin molecules prepared by the method of the present invention simultaneously carry active amine groups, hydroxyl groups, and carboxyl groups. The difference in curing reaction rates between these three groups and the epoxy groups in the TGIC molecules can be used to prepare low-gloss powder coatings (gloss <20%), and the coating film performance can fully meet the various requirements of powder coatings.
