In a document, author is Khademi, Shima, introduce the new discover, Product Details of 645-05-6.
Tungstic acid (H4WO5) immobilized on magnetic-based zirconium amino acid metal-organic framework: An efficient heterogeneous Bronsted acid catalyst for l-(4-phenyl)-2,4-dihydropyrano[2,3c]pyrazole derivatives preparation
A new magnetic nanocatalyst based on the immobilization of tungstic acid onto new design robust, cost-effective, green, and scalable zirconium-L-aspartate amino acid metal-organic framework (MOF)-grafted L-(+)-tartaric acid stabilized magnetite nanoparticles (Fe3O4/tart-NPs) was synthesized by two successive solvo (hydro)-thermal methods. This catalyst was characterized by Fourier-transform infrared (FT-IR), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH), zeta potential, Thermogravimetry Analysis-Differential Thermal Analysis (TGA-DTA), and vibrating sample magnetometer (VSM) analyses. This catalyst is outstanding to prepare l-(4-phenyl)-2,4-dihydropyrano[2,3-c] pyrazole derivatives in aqueous media due to the open metal sites, high and steady proton conductivity in the zirconium-MOF, MIP-202(Zr), and MOF and also due to Bronsted acid properties of tungstic acid. This acidic catalyst can easily be extracted by an outward magnetic field after completion of the reaction without any deactivation or selectivity loss. The products were characterized by spectroscopic analysis (FT-IR, H-1-NMR, and C-13-NMR). The optimized reaction conditions and a possible reaction mechanism are outlined.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 645-05-6 is helpful to your research. Product Details of 645-05-6.
