Chen, Chih-Yu; Tsai, Ming-Li published an article in 2022, the title of the article was Tris(imidazolyl) dicopper(I) complex and its reactivity to exert the catalytic oxidation of sterically hindered phenol substrates via a [Cu2O]2+ core.Electric Literature of 96-76-4 And the article contains the following content:

The Cu ion ligated with histidine residues is a common active site motif of various Cu-containing metalloenzymes exerting versatile catalytic oxidation reactions. Due to the scarcity of structurally characterized biomimetic binuclear Cu(I)-imidazolyl complexes, the bonding interactions between the Cu(I) center and imidazolyl donor ligands as well as their stoichiometric/catalytic oxidation reactivities remain relatively unexplored. In this study, we successfully synthesized a tris(imidazolyl) dicopper(I) complex [CuI(μ-bimeta)3CuI][PF6]2 (1) characterized by single-crystal X-ray diffraction, cyclic voltammetry, and UV-vis absorption spectroscopy. The coordination environment around each Cu(I) center of complex 1 is best described as a regular trigonal geometry and the distance between two Cu(I) centers is ∼3.0521(18) Å. From the O2-/PhIO-titration reactions of complex 1, only 0.5 equivalent of O2(g) and one equivalent of PhIO are required to produce the corresponding oxygenated product complex 1ox, resp., exhibiting a distinct UV-vis absorption band at ∼640 nm. From the characterization of ESI mass spectrometry, IR, UV-vis spectroscopy, and O2-/PhIO-titration reactions, the mol. identity of complex 1ox is tentatively assigned as [Cu(μ-O)(μ-bimeta)3Cu]2+, which is further corroborated by the spectroscopically calibrated DFT calculations The oxidation reactivities of complex 1ox were investigated using the well-understood sterically hindered phenol substrates DTBP and TBBP in both stoichiometric and catalytic fashions. In stoichiometric reactions, one equivalent of 1ox is capable of fully converting TBBP into TBOBF in the CH3CN solution at room temperature within 1 h. The optimized selectivity of catalytically oxidizing DTBP into TBOBF (>95% selectivity, ∼100% conversion rate) could be achieved with a 10 mol% loading of complex 1ox using air as the oxidant. From the time-course product distributions of this catalyst system, ∼40% of DTBP was converted into the corresponding TBBP product in the first 5 min. From 10 to 120 min, the oxidation of DTBP to TBBP and the oxidation of TBBP to TBOBF simultaneously proceeded, which was evidenced by the decrease of TBBP and the increase TBOBF. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Electric Literature of 96-76-4

Wang, Peng; Gu, Xuefan; Wang, Quande; Dong, Jianlong; Dong, Sanbao; Zhang, Jie; Zhu, Shidong; Chen, Gang published an article in 2021, the title of the article was Corrosion inhibition of triazines in sulfur-containing oilfield wastewater.Application of 4719-04-4 And the article contains the following content:

In this study, three kinds of triazines were synthesized via a condensation reaction to inhibit corrosion in oilfield wastewater. The prepared triazines were characterized by IR spectroscopy and gas chromatog.-mass spectrometry, and their performance as eco-friendly corrosion inhibitors in sulfur-containing oilfield wastewater was subsequently evaluated using the weight-loss method and solid-liquid adsorption theory. The results exhibited that triazine II was the most effective corrosion inhibitor in the three and the maximum inhibition efficiency of triazine II (800 mg L-1) can reach 97.66%. The adsorption of the inhibitor was consistent with the assumption of Langmuir adsorption isotherm, the process was spontaneous and chem. adsorption. The mechanism of corrosion inhibition was further explained by desulfurization reaction and coordination bond theory, indicating triazines can be a desulfurizer to synergize their corrosion inhibition in sulfur-containing oilfield wastewater. And their easy adsorption on the steel surface is attributed to nitrogen and oxygen atoms with isolated electron pairs. The above exptl. results all indicate that they have the excellent performance to inhibit corrosion, which can be used in oilfield wastewater treatment and will benefit the related research. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application of 4719-04-4

On April 16, 2020, Wylde, J. J.; Taylor, G. N.; Sorbie, K. S.; Samaniego, W. N. published an article.Safety of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Synthesis and Reaction Byproduct Characterization and Mechanistic Understanding of Hemiformal Based Hydrogen Sulfide Scavengers. And the article contained the following:

When hydrogen sulfide (H2S) gas is produced from oil reservoirs, it leads to a number of well-known problems relating to both metal corrosion and health and safety. Up to a certain concentration (~1000s of ppm in the gas phase) the H2S can be removed by adding a chem. “scavenger” to the system, which reacts with H2S to form less harmful byproducts. A range of different chem. species have been applied as H2S scavengers in petroleum production systems, operating through either oxidative or nonoxidative mechanisms; the former group includes such species as alk. sodium nitrite and hydrogen peroxide, and in the latter group triazine type scavengers have been very prominent. Although triazine based H2S scavengers have been hugely successful in practical and com. terms, there have been associated issues with the related byproducts from the scavenging reaction (discussed in this work). An alternative non-triazine chem. range of H2S scavengers that has emerged in recent years has been based on hemiacetal chemistries, where a hemiacetal is produced by the reaction of an alc. with an aldehyde. Where the aldehyde is formaldehyde, the resulting species are known as hemiformals. In this work, the synthetic chem. reaction pathway for hemiformals based on ethylene glycol and glycerol were studied. This work is novel in four major respects: (i) first, we examine hemiformal production via acid, base, and neutral catalysis systems; (ii) we perform detailed structural determinations of the oligomeric series thus produced (which are different) by analyzing the products by derivatized gas chromatog. mass spectrometry and making subsequent structural assignments; (iii) we then assess the effectiveness of these species as H2S scavenging using an industry standard multiphase test methodol. and make some correlation between their structure and performance; and (iv) finally, we studied the structures of product and byproducts of the scavenging reaction both before and after the scavenging reaction with H2S. This latter part of the study examines issues of byproduct structure early in the development of these newer products in order to address any problems that may be encountered “up front”. This greatly facilitates our application of using hemiformals as fully optimized non-triazine based scavengers by addressing byproduct chem. anal. of these relatively new H2S scavenger systems.

Kremieniewski, Marcin; Jasinski, Bartlomiej; Zima, Grzegorz; Kut, Lukasz published an article in 2021, the title of the article was Reduction of fractionation of lightweight slurry to geothermal boreholes.Reference of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol And the article contains the following content:

When designing the cement slurry for casing string cementing in geothermal boreholes, the appropriate thermal conductivity is selected. In the zone of geothermal water, where thermal energy is collected, cement slurry is used, from which the cement sheath has high thermal conductivity On the other hand, the remaining part of the opening is sealed with slurry, from which the cement sheath will reduce thermal energy losses through appropriate thermal insulation. Cement slurry with appropriate thermal insulation includes light insulating materials. However, the use of such additives is very problematic as they are fractionated due to their low d. Therefore, measures should be taken to prevent fractionation of the cement slurry for sealing geothermal boreholes. This article presents the results of research on fractionation of cement slurries for sealing geothermal boreholes. 12 slurries were used for the tests. Six of them are based on class A cement, and six based on class G cement. This action shows the differences in fractionation depending on the binder used. However, the main area of research is determining the effectiveness of counteracting fractionation by the means used for this purpose. As a result of the conducted works, a very good improvement of the cement slurry stability is obtained after the introduction of xanthan gum, as well as filtration perlite. These measures prevent fractionation, so that the cement slurry has a homogeneous structure, and the cement sheath provides the required thermal insulation in the geothermal well.

Benoite, T.; Vigasini, Nora published an article in 2021, the title of the article was Antioxidant and antidiabetic activities of ethanolic extract of Hibiscus sabdariffa calyx and Stevia rebaudiana leaf.Safety of 2,4-Di-tert-butylphenol And the article contains the following content:

The prevalence of diabetes mellitus has increased tremendously in developing countries of tropical regions. The need for an effective and safe alternative is of importance as oral hypoglycemic drugs have reported to cause side effects on prolonged use. In the present study two tropical plants, Hibiscus sabdariffa calyx and Stevia rebaudiana leaves were assessed for their in vitro antioxidant and antidiabetic activities. Total phenol and flavonoids of ethanolic extracts were quantified. Bioactive compounds were screened by Gas Chromatog. Mass Spectrometry (GC-MS) anal. Antioxidant activity was assessed by 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) and superoxide radical scavenging assays. Antidiabetic ability was evaluated by inhibition of enzymes involved in carbohydrate metabolism Glucose uptake by 3T3-L1 cells was also assessed. Ethanolic extract of Stevia leaf (EtSL) had a higher percentage of phenol and flavonoids. The GC-MS anal. showed the presence of phytochems. like Phenol-2,4-bis (1,1-dimethylethyl) in Roselle calyx and 6-methoxyflavone in Stevia leaves. The antioxidant assessment showed that EtSL significantly inhibited superoxide radical (IC50 = 45.81±1.21 μg/mL). The antidiabetic assessment revealed that Ethanolic extract of Roselle calyx (EtRC) showed strong inhibition of alpha amylase (IC50 = 27.95±0.32 μg/mL) and alpha glucosidase (IC50 = 6.21±0.18 μg/mL). Glucose uptake in 3T3-L1 cells demonstrated that both plants had significant insulin sensitizing ability. It was also revealed that the phenol and flavonoid content strongly correlated with IC50 values of antioxidant and antidiabetic assays. Results of this study show that both plants are a potential source of bioactive phytochems. and can be used as a plant-based antioxidant and antidiabetic agent.
