The extraction equilibrium of four rare earth ions (REⁿ⁺, n = 3 or 4) was investigated in ionic liquid (IL) extraction system using 1-butyl-3-methyl-imidazolium hexafluorophosphate ([Bmim]PF₆) ionic liquid as extraction solvent and 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5 (HPMBP, HP) as extractant. The extraction percentage could be higher than 99%. The extracted species in the REⁿ⁺-[Bmim]PF₆-HP system was neutral REP_n (n = 3 or 4) and complete recovery of REⁿ⁺ extracted into [Bmim]PF₆ can be achieved using diluent HCl as stripping agent. [Bmim]PF₆ can be recycled in the experiment The extraction equilibrium constants and the pH_1/2 values of four REs and their separation factors between adjacent rare earths were estimated and comparatively studied.

The gadolinium extraction by the mixtures of p-phosphorylated calixarene and 1-phenyl-3-methyl-4-benzoyl- pyrazalone-5 from nitrate medium was studied, which indicated an obvious synergistic effect between these two extractants. The extractants exhibit no interaction with each other before the metal extraction Gadolinium(III) was extracted by the species of Ln(PMBP)₂L₂(NO₃) instead of Ln(PMBP)₃·(HPMBP) or Ln(NO₃)₃·2L which are extracted by HPMBP or L alone. Thermodn. functions (ΔG, ΔH, ΔS) were calculated The extraction of other rare earths was also investigated and compared. Possible single rare earth separation was discussed.

Kang, Quan-Peng published the artcileSymmetric containing-PMBP N₂O₂-donors nickel(II) complexes: Syntheses, structures, Hirshfeld analyses and fluorescent properties, Formula: C17H14N2O2, the publication is Polyhedron (2019), 38-50, database is CAplus.

One mononuclear Ni(II) complex [Ni(L¹)(MeOH)₂]·MeOH (1) and two novel trinuclear Ni(II) complexes [Ni₃(L²)₃(EtOH)₆] (2) and [Ni₃(L²)₃(H₂O)₆] (3) constructed from sym. N₂O₂-donors chelating ligands (H₂L¹ and H₂L²) were synthesized and characterized by elemental analyses, FT-IR, UV-Vis spectra and fluorescence spectra. The structures of all three complexes were confirmed by single crystal x-ray diffraction analyses. Complex 1 includes one Ni(II) atom, one completely deprotonated (L¹)^2- unit and two coordinated methanol mols., and forms an infinite 2D supramol. network via the intermol. hydrogen bonds. While complex 2 or 3 is trinuclear with three Ni(II) atoms, three completely deprotonated (L²)^2- units and six coordinated ethanol or H₂O mols. These self-assembling complexes form different dimensional supramol. structures through inter- and intramol. hydrogen bonds. Hirshfeld surface analyses for complexes 1, 2 and 3 were mapped with various functions and further quantification of intermol. interactions was made through the generation of 2D fingerprint plots. In addition, the fluorescence titration experiments were used to characterize fluorescence properties of complexes 1 and 2.

Zainul, Rahadian published the artcileEnhanced electrochemical sensor for electrocatalytic glucose analysis in orange juices and milk by the integration of the electron-withdrawing substituents on graphene/glassy carbon electrode, Computed Properties of 4551-69-3, the publication is Journal of Analytical Methods in Chemistry (2022), 5029036, database is CAplus and MEDLINE.

In this work, a novel electrochem. sensor was developed by electron-withdrawing substituent modification of 1-phenyl-3-methyl-4-(4-fluorobenzoyl)-5-pyrazolone on a graphene-modified glassy carbon electrode (HPMpFP-graphene/GCE) for glucose detection. The results of characterizations using a scanning electron microscope, Fourier transform IR spectroscopy, Raman spectroscopy, and NMR spectroscopy showed the successful fabrication of HPMpFP-graphene nanocomposite, which served as an electroactive probe for glucose detection. The electron transfer ability of HPMpFBP-graphene/GCE has been successfully revealed using cyclic voltammetry and electrochem. impedance spectroscopy results. The good electrochem. performance was shown by well-defined peak currents of square wave voltammetry under various parameters, including pH, HPMpFP and graphene composition, and scan rate effect. A high electrochem. evaluated surface area using chronoamperometry suggested that the present glucose detection response was intensified. The chronoamperometry results at a work potential of 0.4 V presented a wide linear range of 1 x 10³-90渭M and 88-1渭M with 0.74渭M (S/N = 3) as the detection limit. An acceptable recovery has been revealed in the real sample anal. The electrochem. sensing behavior of the composite indicates that it may be a promising candidate for a glucose sensor and it significantly extends the range of applications in the electrochem. field.

Duan, Yu-Lai published the artcileZirconium and hafnium complexes bearing pyrrolidine derived salalen-type {ONNO} ligands and their application for ring-opening polymerization of lactides, HPLC of Formula: 4551-69-3, the publication is Dalton Transactions (2017), 46(34), 11259-11270, database is CAplus and MEDLINE.

The reactions of pyrrolidine derived salalen-type {ONNO} ligands (S)-L^1-3-H₂ with 1 equivalent M(OⁱPr)₄(HOⁱPr) (M = Zr or Hf) in di-Et ether yielded complexes [L^1-3M(OⁱPr)₂] (L = L¹, M = Zr (1); L = L², M = Zr (2), Hf (3); L = L³, M = Zr (4), Hf (5)). All of these complexes were well characterized by NMR spectroscopy, elemental analyses and single-crystal x-ray anal. in the case of complexes 1 and 3–5. X-ray structural determination revealed that these complexes were analogous mononuclear species and had a similar structure in which the metal centers were six-coordinated to two oxygen atoms and two nitrogen atoms of one ligand and two oxygen atoms of two isopropoxy groups. All of these complexes efficiently initialized the ring-opening polymerization of lactides to afford polymers with controlled mol. weight and narrow polydispersity. Furthermore, the ring-opening polymerization of rac-lactide catalyzed by complexes 1–5 afforded isotactic-enriched polymers in solution (P_m = 0.74-0.80) and under melt conditions (P_m = 0.63-0.72).

Wang, Yu published the artcilePreparation of trace single oxidation state plutonium solutions, Product Details of C17H14N2O2, the publication is He Huaxue Yu Fangshe Huaxue (2014), 36(4), 200-204, database is CAplus.

The trace levels of single oxidation state plutonium (Pu(IV,V,VI)) solution was prepared, and the stability was monitored over time. The oxidation state distribution of the solution was analyzed by solvent extraction methods, in which Pu (IV) was extracted with TTA and Pu (IV + VI) was separated by HDEHP. The Pu (IV) solution is prepared by heating the solution until dryness in 1 mol/L HNO₃ repeatedly, and Pu (VI) solution is obtained by keeping Pu (IV) in 0.5-1 mol/L HNO₃-0.1 mmol/L KMnO₄ system for 24 h. Pu (1M) is reduced automatically to Pu (V) in the dark for 5 d. All of these single plutonium solutions could not keep steady in PH = 3.0, 0.01 mol/L NaCl system. Consequently, single oxidation state plutonium solutions need to be prepared freshly for each experiment

Pei, Lixia published the artcileHomo- and copolymerizations of ethylene and norbornene using bis(尾-ketoamino) titanium catalysts containing pyrazolone rings, Related Products of pyrazoles-derivatives, the publication is Polymers (Basel, Switzerland) (2017), 9(7), 262/1-262/12, database is CAplus and MEDLINE.

A series of bis(尾-ketoamino) titanium complexes containing pyrazolone rings (1-3) have been synthesized, characterized, and used as precursors for homo- and copolymerization of ethylene and norbornene. The titanium complexes activated with methylaluminoxane (MAO) exhibited good activities for homopolymerization of ethylene (E) to produce linear polyethylenes (PEs). Ethylene-norbornene copolymers (E-N) were also prepared by these catalysts with moderate activities, and influences of ligand substituents and norbornene addition on copolymer microstructure were studied in detail. Microstructure anal. of the E-N copolymers by ¹³C NMR and differential scanning calorimetry (DSC) techniques showed that alternating (ENEN) and isolated (ENEE) norbornene predominately appeared in the copolymer chain, and the NN dyad and NNN triad sequences were also present in the copolymers obtained by the less bulky catalyst 1.
