On June 9, 2021, Jiang, Peng; Li, Xue-Wen; Wang, Jin-An; Zhou, Xiao-Long published an article.Name: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Kinetic and mechanism studies on the photodegradation of cold-rolling emulsion wastewater by the UV/H2O2 process. And the article contained the following:

The UV/H2O2 process was employed to purify cold-rolling emulsion wastewater (CREW). The degradation of CREW was mainly attributed to the combined UV/H2O2 process and exhibited pseudo-first-order reaction kinetics. The reaction parameters, including the H2O2 dosage, initial pollutant concentration, initial pH, UV intensity, and inorganic anions, were found to influence the removal efficiency of COD (COD) and reaction rates. In addition, the optimal exptl. conditions were determined: H2O2 dosage of 0.2 mol/L, initial pH of 9.13, and UV intensity of 4.0 mW/cm2. The final residual COD concentration decreased from 3573 mg O2/L to 67 mg O2/L, and the treated wastewater complies with the wastewater discharge standards in China (COD concentration of 80 mg O2/L) and can be discharged. Meanwhile, •OH was identified as the primary reactive radical in the process. Sodium dodecyl sulfonate (SDS) and hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine (BK) were selected as representative pollutants in CREW to explore the degradation mechanism. The products generated were identified by liquid chromatog.-mass spectrometry (LC-MS) and gas chromatog.-mass spectrometry (GC-MS). Potential degradation pathways were proposed and discussed. The operational cost is 0.115 USD/L, which was calculated for the best conditions. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Name: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

On January 1, 2022, Montesantos, Nikolaos; Fini, Mahdi Nikbakht; Muff, Jens; Maschietti, Marco published an article.SDS of cas: 4719-04-4 The title of the article was Proof of concept of hydrothermal oxidation for treatment of triazine-based spent and unspent H2S scavengers from offshore oil and gas production. And the article contained the following:

The feasibility of the hydrothermal oxidation of a wastewater derived from H2S scavenging operations, carried out in a topside offshore oil and gas installation, was demonstrated. The feed characterization showed the presence of mainly unreacted triazine (unspent scavenger), monoethanolamine and dithiazine (spent scavengers). The spent and unspent scavengers (SUS) were subjected to hydrothermal oxidation in a batch reactor at approx. 200°C (low temperature, LT) and 350°C (high temperature, HT), using oxygen in excess. The experiments were performed for six reaction times at each temperature, in the range 3 to 360 min at LT and 1 to 120 min at HT. Diluted SUS (COD around 30 g/kg) was used as reactor feed. The three main compounds of the SUS were not found in any of the oxidation products, which means they are fast converted. COD reductions up to 84% and 98% were obtained at LT and HT, resp. A rate equation of second order with respect to the COD was found suitable to represent the rate of disappearance of COD, with the rate constant at HT approx. 70 times higher than at LT. The extensive anal. carried out on the reaction products showed the presence of C1-C4 carboxylic acids, pyridines and pyrazines as intermediate oxidation products. A clear trend towards complete mineralization of organic nitrogen to ammonium, except for small amounts of nitrate at LT, and of organic sulfur towards sulfate, was observed 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

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.

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.

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.

On November 3, 2021, Romero, Iveth; Kucheryavskiy, Sergey; Maschietti, Marco published an article.COA of Formula: C9H21N3O3 The title of the article was Experimental Study of the Aqueous Phase Reaction of Hydrogen Sulfide with MEA-Triazine Using In Situ Raman Spectroscopy. And the article contained the following:

A method for quantitation of bisulfide in the aqueous phase reactions of H2S scavenging with MEA-triazine is proposed. The method is based on time-resolved in situ Raman spectroscopy, thus allowing in situ monitoring of the reactions. The method is applied to obtain the kinetic data of the reactions in batch configuration at room temperature for initial pH values of 9, 10, and 11 and MEA-triazine/bisulfide initial concentration ratios in the range of 0.5-10. The pH increases remarkably during the reactions, causing a substantial decrease in the rate of disappearance of bisulfide. If the system is reacidified, complete depletion of bisulfide can be achieved, evidencing the irreversibility of the scavenging reactions. The results are also supported by a qual. anal. of the trends of the characteristic Raman peaks of MEA-triazine, dithiazine, and monoethanolamine. These trends are in line with the currently accepted reaction scheme, consisting of two scavenging reactions in series.

On March 31, 2008, Selvaraju, Suresh B.; Khan, Izhar U. H.; Yadav, Jagjit S. published an article.Recommanded Product: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Differential biocide susceptibility of the multiple genotypes of Mycobacterium immunogenum. And the article contained the following:

The non-tuberculous mycobacterium Mycobacterium immunogenum colonizes industrial metalworking fluids (MWFs) presumably due to its relative resistance to the currently practiced biocides and has been implicated in occupational respiratory hazards, particularly hypersensitivity pneumonitis. With an aim to understand its inherent biocide susceptibility profile and survival potential in MWF, five different genotypes of this organism, including a reference genotype (700506) and four novel test genotypes (MJY-3, MJY-4, MJY-10 and MJY-12) isolated in our recent study from diverse MWF operations were evaluated. For this, two com. biocide formulations, Grotan (Hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine) and Kathon (5-chloro-2-methyl-4-isothiazolin-3-one) currently practiced for the control of microorganisms, including mycobacteria, in MWF operations were tested. Effect of the fluid matrix on the biocide susceptibility was investigated for the synthetic (S) and semi-synthetic (SS) MWF matrixes. In general, the min. inhibitory concentration values were higher for the HCHO-releasing biocide Grotan than the isothiazolone biocide Kathon. All genotypes (except the reference genotype) showed lower susceptibility in SS as compared to S fluid matrix for Grotan. However, in case of Kathon, a greater susceptibility was observed in SS fluid for majority of the test genotypes (MJY-3, 4 and 10). The test genotypes were more resistant than the reference genotype to either biocide in both fluid types. Furthermore, the individual genotypes showed differential biocidal susceptibility, with MJY-10 being the most resistant. These observations emphasize the importance of using the resistant genotypes of M. immunogenum as the test strains for formulation or development and evaluation of existing and novel biocides, for industrial applications.

On May 31, 2011, Frenzel, Elrike; Schmidt, Stefan; Niederweis, Michael; Steinhauer, Katrin published an article.COA of Formula: C9H21N3O3 The title of the article was Importance of porins for biocide efficacy against Mycobacterium smegmatis. And the article contained the following:

Mycobacteria are among the microorganisms least susceptible to biocides but cause devastating diseases, such as tuberculosis, and increasingly opportunistic infections. The exceptional resistance of mycobacteria to toxic solutes is due to an unusual outer membrane, which acts as an efficient permeability barrier, in synergy with other resistance mechanisms. Porins are channel-forming proteins in the outer membrane of mycobacteria. The authors used the alamarBlue assay to show that the deletion of Msp porins in isogenic mutants increased the resistance of Mycobacterium smegmatis to isothiazolinones (methylchloroisothiazolinone [MCI]/methylisothiazolinone [MI] and octylisothiazolinone [2-n-octyl-4-isothiazolin-3-one; OIT]), formaldehyde-releasing biocides {hexahydrotriazine [1,3,5-tris (2-hydroxyethyl)-hexahydrotriazine; HHT] and methylenbisoxazolidine [N,N’-methylene-bis-5-(methyloxazolidine); MBO]}, and the lipophilic biocides polyhexamethylene biguanide and octenidine dihydrochloride 2- to 16-fold. Furthermore, the susceptibility of the porin triple mutant against a complex disinfectant was decreased 8-fold compared to wild-type (wt) M. smegmatis. Efficacy testing in the quant. suspension test EN 14348 revealed 100-fold improved survival of the porin mutant in the presence of this biocide. These findings underline the importance of porins for the susceptibility of M. smegmatis to biocides.

On December 15, 2021, Nikbakht Fini, Mahdi; Montesantos, Nikolaos; Maschietti, Marco; Muff, Jens published an article.SDS of cas: 4719-04-4 The title of the article was Performance evaluation of membrane filtration for treatment of H2S scavenging wastewater from offshore oil and gas production. And the article contained the following:

After removing H2S from natural gas in offshore oil and gas installations, triazine-based spent scavenger solution remains as a wastewater stream, which in some cases is discharged untreated into the sea. Three nanofiltration (NF) membranes (NF270, NF99HF, and DL), as well as a reverse osmosis (RO) membrane (XLE), were used for TOC reduction from spent and unspent scavenger (SUS) wastewater. The NF270 membrane reduced the TOC of SUS wastewater (61.5 g/L) by 65% while having a superior permeate flux compared to the other studied membranes and thus was subjected to elaborated study. In particular, this membrane showed a separation between the unreacted/unspent scavenger triazine (1,3,5-tris(2-hydroxy-ethyl)hexahydro-s-triazine, HET) and the main spent scavenger reaction product (5-(2-hydroxyethyl)hexahydro-1,3,5-dithiazine, DTZ) as it removed HET by 71% vs. zero removal of DTZ. DTZ is a polar and hydrophobic mol. and consequently passes readily through the membrane despite an expected removal value of 50% based on a simple size exclusion pore flow model. The NF270 permeate was then used as a feed for RO filtration by the XLE membrane to further reduce the TOC of effluent stream by 98% (1.1 g/L). Lastly, both membranes did not demonstrate remarkable fouling when they were tested in 24 h preliminary lab-scale fouling experiments with a constant-concentration feed. This paper is the first published study on SUS wastewater treatment using membrane technol. proving its applicability for total organic carbon (TOC) reduction and simultaneously provides a promising route for further investigations on recovery of unreacted scavenger from spent scavenger compound 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
