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.

Madsen, Henrik T.; Soegaard, Erik G. published an article in 2012, the title of the article was Use of ESI-MS to determine reaction pathway for hydrogen sulphide scavenging with 1,3,5-tri-(2-hydroxyethyl)-hexahydro-s-triazine.SDS of cas: 4719-04-4 And the article contains the following content:

To study the reaction between hydrogen sulfide and 1,3,5-tri-(2-hydroxyethyl)-hexahydro-s-triazine, which is an often used hydrogen sulfide scavenger, electrospray ionisation mass spectrometry (ESI-MS) was used. The investigation was carried out in pos. mode and tandem mass spectrometry was used to investigate the nature of unknown peaks in the mass spectra. The reaction was found to proceed as expected from theory with the triazine reacting with hydrogen sulfide to form the corresponding thiadiazine. This species subsequently reacted with a second hydrogen sulfide mol. to form the dithiazine species, thereby confirming previously obtained results and showing the ability of the ESI-MS method for studying the scavenging reaction. The final theor. product s-trithiane was not detected. Furthermore, fragmentation products of thiadiazine and dithiazine were detected in the solution and possible pathways and structures were suggested to describe the observed fragments. In these, thiadiazine fragmented to 2-(methylidene amino)-ethanol and 2-(1,3-thiazetidin-3-yl)-ethanol and N-(2-hydroxyethyl)-N-(sulfanylmethyl)-ethaniminium, which underwent a further fragmentation to N-methyl-N-(2-oxoethyl)-methaniminium. Dithiazine fragmented to N-methyl-N-(2-oxoethyl)-methaniminium as well. The byproduct from this reaction is methanedithiol, which was not detected due to its low polarity. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).SDS of cas: 4719-04-4

On April 21, 2021, Perez Pineiro, Rolando; Peeples, Craig A.; Hendry, Jonathan; Hoshowski, Jody; Hanna, Gabriel; Jenkins, Alyn published an article.Name: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Raman and DFT Study of the H2S Scavenger Reaction of HET-TRZ under Simulated Contactor Tower Conditions. And the article contained the following:

Raman spectroscopy is a rapid and noninvasive anal. technique used for the anal. of complex materials in complex matrixes. Herein, we report for the first time a combined Raman-DFT study to assign all the vibrational modes associated with the most important species involved in the H2S scavenger reaction of HET-triazine under simulated contactor tower conditions. In doing so, we have defined specific peaks or Raman identifier bands (RIBs) to get a complete reaction profile of the H2S removal process. Our methodol. was able to identify the presence of the elusive 2,2′-(1,3,5-thiadiazine-3,5-diyl)di(ethan-1-ol) (TDZ) intermediate and also provided evidence supporting the formation of the sulfur polymeric deposit from the 2-(1,3,5-dithiazinan-5-yl)ethan-1-ol (DTZ) byproduct.

Madsen, H. T.; Soegaard, E. G. published an article in 2014, the title of the article was Fouling Formation During Hydrogen Sulfide Scavenging With 1,3,5-tri-(hydroxyethyl)-hexahydro-s-triazine.Electric Literature of 4719-04-4 And the article contains the following content:

To investigate if the hydrogen sulfide scavenger, 1,3,5-tri-(hydroxyethyl)-hexahydro-s-triazine, could explain a severe carbon/sulfur rich fouling found at a refinery, experiments were conducted to study the scavenging process and the composition of the fouling. The reaction was analyzed with electro spray ionization mass spectrometry (ESI-MS), and the fouling with IR spectroscopy and X-ray diffraction. The fouling was found to be a byproduct of the scavenging reaction, and to consist of dithiazine mols. with linking carbon-sulfur chains. ESI-MS anal. strongly indicates that these chains are generated when dithiazine decomposes to smaller mols., which through condensation reactions with dithiazine forms the fouling.

Turkiewicz, Anna; Steliga, Teresa; Kluk, Dorota; Gminski, Zbigniew published an article in 2021, the title of the article was Biomonitoring Studies and Preventing the Formation of Biogenic H2S in the Wierzchowice Underground Gas Storage Facility.Electric Literature of 4719-04-4 And the article contains the following content:

The article discusses the results of biomonitoring research at the Underground Gas Storage (UGS). Hydrogen sulfide, as one of the products of microbiol. reaction and transformation, as well as a product of chem. reactions in rocks, is a subject of interest for global petroleum companies. The materials used in this research work were formation waters and stored natural gas. The biomonitoring of reservoir waters and cyclical analyses of the composition of gas stored at UGS Wierzchowice enabled the assessment of the microbiol. condition of the reservoir environment and individual storage wells in subsequent years of operation. Investigations of the formation water from individual wells of the UGS Wierzchowice showed the presence of sulfate reducing bacteria bacteria (SRB), such as Desulfovibrio and Desulfotomaculum genera and bacteria that oxidize sulfur compounds In the last cycles of UGS Wierzchowice, the content of hydrogen sulfide and sulfides in the reservoir waters ranged from 1.22 to 15.5 mg/dm3. The monitoring of natural gas received from UGS production wells and observation wells, which was carried out in terms of the determination of hydrogen sulfide and organic sulfur compounds, made it possible to observe changes in their content in natural gas in individual storage cycles. In the last cycles of UGS Wierzchowice, the content of hydrogen sulfide in natural gas from production wells ranged from 0.69 to 2.89 mg/dm3, and the content of organic sulfur compounds converted to elemental sulfur ranged from 0.055 to 0.130 mg Sel./Nm3. A higher hydrogen sulfide content was recorded in natural gas from observation wells in the range of 2.02-25.15 mg/Nm3. In order to explain the causes of hydrogen sulfide formation at UGS Wierzchowice, isotopic analyses were performed to determine the isotope composition of δ34SH2S, δ34SSO4, δ18OSO4 in natural gas samples (production and observation wells) and in the deep sample of reservoir water. The results of isotope tests in connection with microbiol. tests, chromatog. analyses of sulfur compounds in natural gas collected from UGS Wierzchowice and an anal. of the geol. structure of the Wierzchowice deposit allow us to conclude that the dominant processes responsible for the formation of hydrogen sulfide at UGS Wierzchowice are microbiol., consisting of microbial sulfate reduction (MSR). The presented tests allow for the control and maintenance of hydrogen sulfide at a low level in the natural gas received from the Wierzchowice Underground Gas Storage facility.

On January 31, 2007, Hua, Guoxiong; Zhang, Qingzhi; McManus, Derek; Slawin, Alexandra M. Z.; Woollins, J. Derek published an article.SDS of cas: 4719-04-4 The title of the article was Improvement of the Fe-NTA sulfur recovery system by the addition of a hydroxyl radical scavenger. And the article contained the following:

The degradation of nitrilotriacetic acid (NTA), which results from the oxidation of hydroxyl radicals formed in the process, is a major deficiency in the present Fe-NTA system for the oxidation of hydrogen sulfide to sulfur by air. The degradation of NTA can be slowed down considerably by the addition of a hydroxyl radical scavenger. In this study, a series of inorganic and organic materials was tested as scavengers / inhibitors of hydroxyl radicals in attempts to improve the Fe-NTA system. The results showed that N-methylpyrrolidinone and ethylene glycol could be used as potentially powerful scavengers of hydroxyl radicals to improve the Fe-NTA system.

Canuto, Andre V. S.; Echevarria, Aurea published an article in 2014, the title of the article was 1H NMR for quantifying sulfide trapping efficiency by using 1,3,5-tris(2-hydroxyethyl)-1,3,5-triazinane.Application of 4719-04-4 And the article contains the following content:

H2S is an extremely toxic colorless gas; it is corrosive and denser than air. It usually happens in oil and natural gas fields, refineries, coal mines, and in some industrial effluent treatment systems. This work presents an alternative method of monitoring and quantifying H2S trapping efficiency using 1,3,5-tris(2-hydroxyethyl)-1,3,5-triazinane as a sequestering agent, and Na sulfide as a source of sulfide ion, through 1H NMR spectroscopy. The results proved that the reaction occurs very quickly at 20° at pH 7 and 10. here, 3,5-di(2-hydroxyethyl)-1,3,5-thiodiazinane and 5-(2-hydroxyethyl)-1,3,5-dithiozinane were observed and quantified; it was evidenced that 1H NMR spectroscopy can be applied as a fast and effective method to quantify H2S trapping efficiency.
