Separation of chalcopyrite from galena with 3-amyl-4-amino-1, 2, 4-triazole-5-thione collector: Flotation behavior and mechanism

3-Amyl-4-amino-1,2,4-triazole-5-thione (AATT) reacted with Cu2+ or Pb2+ ions in aqueous solutions to form CuAATT and Pb(AATT)(2) complexes and their solubility product constants were measured as 10(-16.17) and 10(-20.60), respectively. In the moderately-alkaline media, both chalcopyrite and galena chemisorbed AATT on to their surfaces, and the adsorption amount of AATT on chalcopyrite was bigger than that on galena, which rendered a stronger hydrophobization toward chalcopyrite. While under the high-alkaline pulp, AATT only chemisorbed on chalcopyrite, not on galena. The micro-flotation findings indicated that AATT was a favorable collector for flotation enrichment of chalcopyrite and galena at pH <11.0, and realized an efficient flotation separation of chalcopyrite from galena under pH>11.5. The CuAATTcomplex was more insoluble than Pb(AATT)2, which implied a stronger affinity of AATT toward chalcopyrite than galena and returned their selective flotation separation at the high-alkaline condition.

Copolymers of Methyl Acrylate and Vinylazoles: Synthesis, Thermolabile Properties, and Grafting of Polyamine Chains

New copolymers of methyl acrylate with 1-vinylimidazole, 1-vinyl-1,2,4-triazole, and 4-vinyl-1,2,3-triazole are synthesized by radical copolymerization. It is shown that the reactivity ratios for methyl acrylate and 1-vinylimidazole are 0.83 +/- 0.09 and 0.25 +/- 0.02, for methyl acrylate and 1-vinyl-1,2,4-triazole are 1.0 +/- 0.04 and 0.27 +/- 0.01, and for methyl acrylate and (4-vinyl-1H-1,2,3-triazolyl)-methyl pivalate are 0.56 +/- 0.03 and 2.90 +/- 0.20, respectively. The behavior of the copolymers in aqueous media and their thermoresponsive properties are studied by potentiometric titration and dynamic light scattering. Copolymer macromolecules occur in aqueous solutions in the form of large associates the fraction of which increases upon heating; in some cases, an insoluble phase is formed. It is found that the copolymers with the grafted oligopropylamine moieties containing N-vinylazole units can interact with the DNA oligonucleotide, stimulating their research as agents for the delivery of nucleic acids to living cells.

Novel triazole derivatives as ecological corrosion inhibitors for mild steel in 1.0 M HCl: experimental & theoretical approach

The present paper illustrates the investigation of two novel ecological triazole derivative corrosion inhibitors, namely ethyl 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetate [Tria-CO2Et], and 2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetohydrazide [Tria-CONHNH2]. The studied inhibitors were investigated against the corrosion of mild steel in 1.0 M HCl solution using different electrochemical techniques. Potentiodynamic polarization experiments indicated that the [Tria-CO2Et], and the [Tria-CONHNH2] acted as mixed type inhibitors. Electrochemical impedance spectroscopy measurements revealed that both inhibitors presented a high inhibition performance, achieving an inhibition efficiency of 95.3% for [Tria-CO2Et] and 95.0% for [Tria-CONHNH2] at a concentration of 1.0 x 10(-3) M. Based on the Langmuir isotherm model and the activation parameters, these triazole derivatives were adsorbed onto a steel surface by physical and chemical bonds. Density functional theory based on B3LYp6-311G(d,p) was also carried out to correlate the inhibition efficiencies obtained experimentally with the theoretical descriptors of the studied molecular structures.

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 584-13-4 is helpful to your research. Computed Properties of C2H4N4.

Thermodynamics of transfer and partition of 3,5-diamino-1-phenyl-1,2,4-triazole in the 1-octanol/water biphasic system

In this paper, we focus for the first time on thermodynamics of transfer of 3,5-diamino-1-phenyl-1,2,4-triazole (DAPT) from water to liquid 1-octanol which is considered in pharmaceutical chemistry as an appropriate model of a lipid-like environment for studying a passive membrane transport of various drugs. The enthalpies of solution of DAPT have been determined calorimetrically in both solvents at 298.15, 308.15 and 328.15 K. The partition coefficients (P) have been obtained in the 1-octanol/water biphasic system at 298.15 and 328.15 K using a classical isothermic saturation method. Standard thermodynamic functions of DAPT transfer from water to a lipid-like phase have been calculated via the Gibbs-Helmholtz equation using the temperature dependence of the standard enthalpies of solution and the partition coefficient at the reference temperature of 298.15 K. We have found that the enthalpic term favours the solute transfer both at lower and elevated temperatures, whereas the entropic one contributes in the opposite manner. The free energy of transfer remains negative for all the temperature range studied indicating rather appreciable affinity of a potential drug towards a lipid-like environment. The comparison of the experimental and calculated P values indicates that our approach is able to predict with a good accuracy the behaviour of the 1,2,4-triazole derivatives for the physiological temperature range.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 584-13-4, in my other articles.

Dynamics of Aspergillus fumigatus in Azole Fungicide-Containing Plant Waste in the Netherlands (2016-2017)

The treatment of patients suffering from Aspergillus diseases is hampered due to infections with Aspergillus fumigatus that are already resistant to medical azoles. Previous work has suggested that A. fumigatus likely gains resistance through environmental azole exposure in so-called hot spots. Here, we investigated A. fumigatus resistance dynamics over time at three sites at which farmers used azole fungicides for crop protection. Over 16 months, 114 samples were taken from stockpiles of decaying plant waste. A. fumigatus and azole fungicide residues were ubiquitously present in the plant waste. On average, 105 A. fumigatus CFU/g was recovered, of which roughly half were itraconazole and tebuconazole resistant. Similar tandem repeat-mediated resistance mechanisms were found in colonies cultured from plant waste as reported in clinical azole-resistant isolates. Our results show a consistent high burden of azole-resistant A. fumigatus in azole-containing plant waste and underscores the need to further investigate resistance-reducing interventions and transmission routes. IMPORTANCE Aspergillus fumigatus is consistently present independently on season at a high abundance in plant waste material throughout the sampling period. Our study confirmed that long-term storage sites of azole-containing decaying plant material can indeed be considered hot spots, which can sustain resistance development and maintenance in A. fumigatus. Roughly half of individual isolates were azole resistant and carried genetic mutations that are highly similar to those found in patients with azole-resistant invasive aspergillosis. Our work suggests that environmental sources of azole resistance in A. fumigatus may be important, underscoring the need for further studies on environment-to-patient transmission routes.

Magnetic metal-organic framework MIL-100 (Fe)/polyethyleneimine composite as an adsorbent for the magnetic solid-phase extraction of fungicides and their determination using HPLC-UV

Fe3O4@MIL-100 (Fe)/PEI are used for the first time as an adsorbent material for the extraction of pesticide residues (epoxiconazole, flusilazole, tebuconazole, and triadimefon) from food matrices. The adsorbent proposed (Fe3O4@MIL-100(Fe)/PEI) was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), thermogravimetric (TG) analysis, and vibrating sample magnetometer (VSM) techniques to evaluate the properties of the sorbent. Then, the Fe3O4@MIL-100 (Fe)/PEI was employed for the quantification of the four triazole fungicides in fruits and vegetables (apple, orange, tomato, cabbage, and cucumber) using HPLC-UV for separation and detection. During the extraction process, the main parameters such as amount of adsorbent, extraction time, pH value, ionic strength, eluting solvent, and eluting volume were optimized. Under the optimum conditions, good linearity of this method was observed for all analytes, with correlation coefficients (R-2)>= 0.9908. The limits of detection (LODs) ranged from 0.021-3.04 mu g kg(-1). The extraction recoveries of the four triazole fungicides varied from 73.9 to 109.4% with relative standard deviations (RSD) in the range 0.5 to 6.2%. Compared with other MOFs, the modification of Fe3O4@MIL-100 (Fe) with PEI shows high efficient adsorption due to the combined benefits of MIL-100 (Fe) and PEI. The material is easily synthesized, has good stability, and is of low cost.

Synthesis, characterization and cytotoxic activity evaluation of 4-(1,2,3-triazol-1-yl) salicylic acid derivatives

A novel series of 4-(1,2,3-triazol-1-yl) salicylic acid derivatives was synthesized from 4-azidosalicylic acid and diverse alkynes using copper catalyzed azide-alkyne cycloaddition as key process and fully characterized by using different analytical techniques. The in vitro antiproliferative activity of these new compounds was explored against a series of tumoral cell lines which included U251 (human glioblastoma), PC-3 (human prostate cancer cell line), K562 (human leukemia), HCT-15 (human colorectal adenocarcinoma), MCF-7 (human breast adenocarcinoma) and SKLU (human lung adenocarcinoma), showing selective activity in some compounds. Moreover, molecular docking studies suggest a strong interaction between ARG-154 in STAT3 and the triazole fragment which can explain the inhibitory activity observed in these compounds.
