On September 12, 2012, Taylor, Grahame N.; Prince, Philippe; Matherly, Ron; Ponnapati, Ramakrishna; Tompkins, Rose; Vaithilingam, Panchalingam published an article.Application In Synthesis of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Identification of the Molecular Species Responsible for the Initiation of Amorphous Dithiazine Formation in Laboratory Studies of 1,3,5-Tris (hydroxyethyl)-hexahydro-s-triazine as a Hydrogen Sulfide Scavenger. And the article contained the following:

Amorphous dithiazine is produced from a solution of tris-(2-hydroxyethyl)-hexahydro-s-triazine (I) that is heavily consumed by hydrogen sulfide (H2S). Previously, it has been reported that the chem. structure of amorphous dithiazine is a polymeric structure which involves opening of the dithiazine ring. Evidence is presented here that the first step in this polymerization reaction is conversion of the terminal hydroxyl functionality into a terminal thiol. Thereafter, the thiol initiates the ring opening of the dithiazine to yield a polymeric, highly insoluble material. It has been observed that the critical chem. species in the initiation of this chain reaction is the bisulfide anion. This bisulfide anion is produced from the reaction of H2S with ethanolamine liberated in the sulfur insertion reaction undergone by tris-(2-hyroxyethyl)-hexahydro-s-triazine (I). This process has been artificially induced by the reaction of monomeric or crystalline 5-hydroxyethyldithiazine (II) and ethanolammonium hydrosulfide. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Application In Synthesis of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

On September 18, 2018, Wang, Xiaoting; Zheng, Yajun; Shi, Jun; Gong, Xiaoyun; Ji, Yue; Han, Weiwei; Jiang, You; Austin, Daniel E.; Fang, Xiang; Zhang, Zhiping published an article.Computed Properties of 4719-04-4 The title of the article was Elucidating the Reaction Mechanisms between Triazine and Hydrogen Sulfide with pH Variation Using Mass Spectrometry. And the article contained the following:

Triazine is one of the most economical and effective scavengers for hydrogen sulfide (H2S) removal, but the reaction mechanisms between triazine and H2S with pH variation in solution are still poorly understood. Herein, we show that the reaction process can be directly probed by means of paper spray mass spectrometry, in which an aprotic solvent (e.g., acetonitrile) is more favorable to the observation of reaction intermediates than a protic solvent (e.g., methanol), because of hydrogen bond interaction. Varying the pH of the reaction leads to completely different reaction pathways. With the pH in the range of 5.58 to 7.73, the major product was thiadiazine. With a pH of 3.02-3.69, thiadiazine is converted to 2-(5-(2-hydroxyethyl)-1,3,5-thiadiazinan-3-yl)acetaldehyde, which differs from the traditional pathway of analogous reactions. However, as ammonia was added into the reaction and the pH was adjusted to the range 8.45-9.43, triazine readily undergoes hydrolysis, and the formed intermediate reacts with ammonia and formaldehyde generated in situ from triazine to produce 1-(2-hydroxyethyl)-3,5,7-triaza-1-azoniatricyclo [3.3.1.13,7]decane (HTAD). Further increasing the pH up to 10.27-11.21 leads to the decomposition of HTAD. Based on the exptl. observation and evidence from high-resolution and tandem mass spectrometry, we propose the plausible reaction mechanisms between triazine and H2S, as well as the derived reaction from triazine under different pH conditions. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Computed Properties of 4719-04-4

Al-Sabagh, A. M.; Kandile, N. G.; Nasser, N. M.; Mishrif, M. R.; El-Tabey, Amira E. published an article in 2014, the title of the article was Demulsification Efficiency of Some New Demulsifiers Based on 1,3,5-Triethanolhexahydro-1,3,5-triazine.Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol And the article contains the following content:

This study mainly concentrates on the synthesis of three novel demulsifiers and the investigation of their demulsification efficiency. The demulsifiers were derived from 1,3,5-triethanolhexahydro-1,3,5-triazine, which was prepared by the reaction of monoethanol amine with formaldehyde. The 1,3,5-triethanolhexahydro-1,3,5-triazine was ethoxylated by introducing 20 units of ethylene oxide and then esterified at different molar ratios with oleic acid (1, 2, and 3) to give three demulsifiers, namely, E20TO, E20TO2, and E20TO3. The chem. structures of the prepared demulsifiers were confirmed by 1H NMR and FTIR spectrum. The demulsification efficiency of these demulsifiers was tested on the natural water-in-oil (w/o) emulsions (50% water content). From the obtained results, it has been found that the investigated demulsifiers have a great potential to break the w/o emulsions. The trioleat ester (E20TO3) exhibited the maximum demulsification efficiency (96%) after 120 min at 55°C. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

Rima, Maya; Trognon, Jeanne; Latapie, Laure; Chbani, Asma; Roques, Christine; El Garah, Fatima published an article in 2022, the title of the article was Seaweed Extracts: A Promising Source of Antibiofilm Agents with Distinct Mechanisms of Action against Pseudomonas aeruginosa.Application In Synthesis of 2,4-Di-tert-butylphenol And the article contains the following content:

The organization of bacteria in biofilms is one of the adaptive resistance mechanisms providing increased protection against conventional treatments. Thus, the search for new antibiofilm agents for medical purposes, especially of natural origin, is currently the object of much attention. The objective of the study presented here was to explore the potential of extracts derived from three seaweeds: the green Ulva lactuca, the brown Stypocaulon scoparium, and the red Pterocladiella capillacea, in terms of their antibiofilm activity against P. aeruginosa. After preparation of extracts by successive maceration in various solvents, their antibiofilm activity was evaluated on biofilm formation and on mature biofilms. Their inhibition and eradication abilities were determined using two complementary methods: crystal violet staining and quantification of adherent bacteria. The effect of active extracts on biofilm morphol. was also investigated by epifluorescence microscopy. Results revealed a promising antibiofilm activity of two extracts (cyclohexane and Et acetate) derived from the green alga by exhibiting a distinct mechanism of action, which was supported by microscopic analyses. The Et acetate extract was further explored for its interaction with tobramycin and colistin. Interestingly, this extract showed a promising synergistic effect with tobramycin. First analyses of the chem. composition of extracts by GC-MS allowed for the identification of several mols. Their implication in the interesting antibiofilm activity is discussed. These findings suggest the ability of the green alga U. lactuca to offer a promising source of bioactive candidates that could have both a preventive and a curative effect in the treatment of biofilms. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Application In Synthesis of 2,4-Di-tert-butylphenol

And the article contained the following:

Triazole herbicide, Thiencarbazone-Me (TCM) applied on different crops for weedicidal activity is associated with an inherent toxicity towards bladder and urinary functionality. TCM has been first time explored for its biodegradative behavior utilizing microbes, previously isolated from soils. Simulated bio-transformation assemblies of five fungal strains; Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN), Aspergillus terrus (AT), Aspergillus fumigatus (AFu) and two bacterial strains: Xanthomonas citri (XC), Pseudomonassyringae (PS), were utilized. 10 mg/L TCM concentration was set up utilizing each microbe and analyzed for 42 days. TCM bio-degradation was evaluated by UV-Visible spectrophotometery and gas chromatog. mass spectroscopy. Aspergillus terrus (R2 = 0.86) and Penicillium chrysogenum (R2 = 0.88) exhibited highest capability to metabolize TCM while forming intermediate metabolites including; 2,4-dihydro-[1,2,4] triazol-3-one, semicarbazide and urea, Me 4-isocyanatosulfonyl-5-methylthiophene-3-carboxylate. TCM degradation by all strains AF, AFu, AN, PC, AT, PS and XC was found to be 74, 74, 81, 95, 98, 90 and 95%, resp. after 42 days elucidating the effectiveness of all the utilized strains in degrading TCM. Furthermore, present research can be extended to the optimization of the bio-deteriorative assays to be employed on the practical scale for the successful management of environment through sustainable and cost effective ways.

On February 29, 2008, Steinhauer, K.; Goroncy-Bermes, P. published an article.Application of 4719-04-4 The title of the article was Treatment of water-based metalworking fluids to prevent hypersensitivity pneumonitis associated with Mycobacterium spp.. And the article contained the following:

To prevent further outbreaks of hypersensitivity pneumonitis (HP), biocides are required which are capable of protecting water-based coolants from proliferating mycobacteria. The aim of this study was therefore, to test different biocide preparations on their mycobactericidal activity. Minimal inhibitory concentration values were determined for Mycobacterium chelonae and Mycobacterium immunogenum for triazine-based, methyloxazolidine-based, N/O-formal-based biocidal formulations. All biocides were effective already at a low dosage (<0.05%) irresp. of the presence or absence of organic soiling, except for one N/O-formal-based formulation containing Kathon 886 (CMI). Quenching of CMI in the presence of organic soiling was found to account for loss in efficacy as determined by high-performance liquid chromatog. measurement. Preservation tests were carried out to investigate the efficacy of the biocidal preparations under practical conditions. Results indicate that methyloxazolidine-based biocidal preparations were most effective to prevent coolants from microbial contamination including rapidly growing mycobacteria. Furthermore, it could be demonstrated that common dipslides can be used to easily monitor coolants for contamination by mycobacteria. Our data does not support the hypothesis that mycobacterial proliferation is enhanced by the reduction of competitive microbial population by biocides such as triazines as described earlier but rather suggests a protective effect of biocides regarding mycobacteria in the presence of competitive microbial flora, thereby preventing further outbreaks of HP. 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

Jam, Neda; Hajimohammadi, Reza; Gharbani, Parvin; Mehrizad, Ali published an article in 2021, the title of the article was Evaluation of antibacterial activity of aqueous, ethanolic and methanolic extracts of areca nut fruit on selected bacteria.Product Details of 96-76-4 And the article contains the following content:

Today, the tendency to use of natural preservatives to increase food security has expanded. In the present study, antibacterial effects of Areca Nut fruit extracts were evaluated against Staphylococcus aureus, Escherichia coli, Salmonella enterica, and Enterobacter aerogenes bacteria using agar disk diffusion technique. Methanol, ethanol, and water were used as solvents for extraction by maceration method, and extracts were analyzed by GC-MS. The antibacterial activity was evaluated using microtiter broth dilution method to determine min. inhibitory concentration (MIC) and min. bactericidal concentration (MBC). Results revealed that all ATCC strains were significantly inhibited by ethanolic and methanolic extracts Escherichia coli produced a significantly larger zone of inhibition for Gentamicin (35 ± 0.65 mm) and Penicillin (25 mm ± 0.56), while Enterobacter aerogenes produced smaller zone of inhibition for Gentamicin (20 ± 0.87 mm) and Penicillin (15 ± 0.87 mm). Also, methanolic extract had considerable antibacterial activity with MIC value of 1.56 mg/mL against Escherichia coli. All of extracts were used to evaluate antibacterial effects in prepared cake, and as a result, all pathogenies were the most sensitive by methanolic extract in 100 mg/L of concentration except Escherichia coli that were more sensitive by ethanolic extract In conclusion, the Areca Nut fruit extracts may be used as a natural preservative in food industries. Future studies should focus on the effect of Areca Nut fruit extracts in bakery and drinking industries. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Product Details of 96-76-4
