6-Acetylpicolinic acid (cas: 122637-39-2) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Recommanded Product: 6-Acetylpicolinic acid

The synthesis, Eu3+ complexation, and selective solvent extraction of Am3+ over Eu3+ in nitric acid solution by 2-carboxamido-6-(1H-pyrazol-3-yl)-pyridines (A-PzPy) ligands were described. Without the aid of any lipophilic anion source, A-PzPy ligands in Me iso-Bu ketone (MIBK) diluent demonstrated a more favorable affinity of Am3+ than Eu3+ at high acidity levels. Slope anal. showed the formation of 1:2 metal/ligand extracted species. The extraction was a spontaneous exothermic process. The analyses of fluorescence titration, Fourier transform IR (FT-IR), Raman, time-resolved laser fluorescence spectrum (TRLFS), electrospray ionization mass spectrometry (ESI-MS), conductivity and microcalorimetric titration revealed that the composition of complex is [Eu(NO3)2(H2O)•2(Et-p-Tol-A-PzPy)](NO3). Combining the results of solvent extraction and complexation study, the extraction mechanism was proposed. stability constants (log β) and thermodn. parameters (ΔH, ΔS, ΔG) for complexation of Eu3+ with Et-p-Tol-A-PzPy are presented. In the experiment, the researchers used many compounds, for example, 6-Acetylpicolinic acid (cas: 122637-39-2Recommanded Product: 6-Acetylpicolinic acid).
