Flowerlike copper(II)-based coordination polymers particles: Rapid room-temperature fabrication, influencing factors, and transformation toward CuO microstructures with good catalytic activity for the reduction of 4-nitrophenol

A facile and environment-friendly approach for synthesis of flowerlike copper-based coordination polymer particles (CPPs) was reported. Copper acetate (CuAc2) and sodium pyridine-2,3-dicarboxylate (2,3-Na2PDC) were used as the initial reactants. The flowerlike Cu-PDC microstructures were obtained based on a simple direct precipitation between CuAc2 and 2,3-Na2PDC in a mixed solution of water and methanol with the volume ratio of 20:10 at room temperature. The as-obtained products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), and elemental analysis. Some factors to affect the morphology and size of the Cu-PDC microstructures were systematically investigated such as the molar ratio of reactants, the volume ratio of water/methanol, acetic groups, and the reaction time. It was found that flowerlike Cu-PDC microstructures could be transformed into flowerlike CuO microstructures by heat-treating in air at 350 °C for 30 min. Experiments showed that the as-obtained flowerlike CuO microstructure exhibited a high catalytic activity for the reduction of 4-nitrophenol in excess NaBH4 solution.

Process for producing high-purity 2,3-pyridinedicarboxylic acid

A process for producing 2,3-pyridinedicarboxylic acid having a significantly decreased heavy metal content and capable of satisfying the purity level required for medicinal and agricultural chemicals comprising the steps of: adding at least one sulfur-containing substance selected from a hydrosulfide, a sulfide, a polysulfide, and sulfur to an aqueous solution of 2,3-pyridinedicarboxylic acid or its salt; removing the resulting precipitates from the solution; acidifying the solution with a mineral acid to precipitate 2,3-pyridinedicarboxylic acid; and recovering the precipitates. The aqueous solution to be treated may be an aqueous solution of an alkali metal salt of 2,3-pyridinedicarboxylic acid obtained by alkali decomposition of 2,3-pyridinedicarboxylic acid copper (II) salt, which has been formed or precipitated in a process for producing 2,3-pyridinedicarboxylic acid.

Process for producing 2,3-pyridinedicarboxylic acid

Highly pure 2,3-pyridinedicarboxylic acid is produced by a process suitable for application in commercial production with a high yield and with recirculation of waste liquor. The process comprises the steps of: (a) oxidizing quinoline or 8-hydroxyquinoline in a solvent in the presence of copper (II) ions to precipitate copper (II) salt of 2,3-pyridinedicarboxylic acid and then separate the precipitates, (b) reacting the separated copper (II) salt with an alkali in a solvent to obtain a solution of an alkali metal salt of 2,3-pyridinedicarboxylic acid, and (c) reacting the solution of the alkali metal salt with a mineral acid to precipitate 2,3-pyridinedicarboxylic acid and then separate the precipitates, and is characterized in that (A) part or all of the solution obtained after the precipitated 2,3-pyridinedicarboxylic acid is separated in step (c) is used as at least part of the solvent in step (a) or (b), or (B) copper or a copper compound is added to the solution obtained after the precipitated 2,3-pyridine-dicarboxylic acid is separated in step (c) to recover the 2,3-pyridinedicarboxylic acid remaining in the solution as its copper (II) salt.
