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

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.

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.

On May 20, 2014, Taylor, Grahame N.; Matherly, Ron published an article.SDS of cas: 4719-04-4 The title of the article was Use of Portable Analytical Methods to Determine the Stoichiometry of Reaction for Hexahydrotriazine-Based Hydrogen Sulfide Scavenger Operations. And the article contained the following:

During the reaction between 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine and hydrogen sulfide, the principle byproduct is the organic sulfide 5-(2-hydroxyethyl)dithiazine. It can be determined by a novel, portable, field-capable ion mobility spectrometry method described herein and enables the degree spent to be determined Dependant upon the level of carbon dioxide in the produced gas, a mixture of ethanolaminium bicarbonate and ethanolamine bisulfide is also produced. Using a field capable spectrophotometric method the level of inorganic sulfide can be determined, thus allowing the ethanolaminium bisulfide concentration to be calculated Provided the fluid is only partially spent, and there is some unreacted 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine remaining; the only source of inorganic sulfide is the amine salt. From a knowledge of the original fluid concentration, the combination of these two methods allows the effective stoichiometry, or observed molar reaction proportions between 1,3,5-tris(2-hydroxyethyl)hexahydro-s-triazine and hydrogen sulfide, to be measured for a specific field location.

Pretty, Jack; Glaser, Robert; Jones, Johnny III; Lunsford, R. Alan published an article in 2004, the title of the article was A technique for the identification and direct analysis of hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine in metalworking fluids using electrospray-mass spectrometry.COA of Formula: C9H21N3O3 And the article contains the following content:

Hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine is a widely used biocide in metalworking fluids that resists direct quantification in many anal. methods due to instability. It can be detected in electrospray-mass spectrometry (ES-MS) due to the formation of a charged and relatively stable adduct with the sodium ion. This adduct produces a distinct ion spectrum via collision-induced fragmentation, which should promote specific detection of the analyte in complex matrixes. ES-MS detection of the analyte added to, or already present in, metalworking fluid samples at μg mL-1 levels is demonstrated. Parameters affecting the formation and detection of the sodium adduct, including choice of solvent, alkalinity, and sodium ion level are explored. Linearity of response in flow injection mode is demonstrated.

On June 30, 2006, Fekete, Agnes; Hertkorn, Norbert; Frommberger, Moritz; Lahaniatis, Majlinda R.; Kettrup, Antonius; Schmitt-Kopplin, Philippe published an article.SDS of cas: 4719-04-4 The title of the article was Development of a capillary electrophoresis-mass spectrometry method for the determination of formaldehyde releasers as their hydrolysis products and amino alcohols from metal working fluids. And the article contained the following:

Metal working fluids (MWFs) are widely used as lubricants and coolants for different industrial operations. Biocides are ingredients of MWFs to control the microbial growth; derivatives of hexahydrotriazines and oxazolidines are generally used. Because of the lack of appropriate characterization, an existing capillary electrophoretic method for their quantification was improved. During the process of optimization, it became clear that hydrolysis products, derivatives of amino alcs., severely interfere with the separation procedure. Since indirect-UV detection lacked the required selectivity, mass-selective detection was employed. NMR and MS established the absence of amino alcs. in the original products. The aqueous solutions of the biocides stored for extended time remained amino alc.-free, suggesting that these amino alcs. are formed from the biocides during the capillary electrophoretic separation The observation of narrow and sym. peaks indicated hydrolysis, and the polarity of the products implied favorable conditions for capillary electrophoretic separation Methods were optimized for the anal. of the amino alcs., the hydrolytic products of the formaldehyde releasers, using indirect-UV and MS detection. This method was extended to other likely solutes used as alk.-reserve ingredients. The analytes were separated within 9 min with a high precision of migration times (the RSDs were <1.5%). When quantifying from mobility scale, the calibration curves produced linearity with regression coefficients at 0.990-0.999. The detection limit was <1 mg/L in the case of MS detection. The influence of water-based MWF was also studied, and no matrix effect on the migration of the analytes and on the peak areas 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

Kowalski, Piotr S.; Capasso Palmiero, Umberto; Huang, Yuxuan; Rudra, Arnab; Langer, Robert; Anderson, Daniel G. published an article in 2018, the title of the article was Ionizable amino-polyesters synthesized via ring opening polymerization of tertiary amino-alcohols for tissue selective mRNA delivery.Electric Literature of 4719-04-4 And the article contains the following content:

The utility of mRNA (mRNA) as a therapy is gaining a broad interest due to its potential for addressing a wide range of diseases, while effective delivery of mRNA mols. to various tissues still poses a challenge. This study reports on the design and characterization of new ionizable amino-polyesters (APEs), synthesized via ring opening polymerization (ROP) of lactones with tertiary amino-alcs. that enable tissue and cell type selective delivery of mRNA. With a diverse library of APEs formulated into lipid nanoparticles (LNP), structure-activity parameters crucial for efficient transfection are established and APE-LNPs are identified that can preferentially home to and elicit effective mRNA expression with low in vivo toxicity in lung endothelium, liver hepatocytes, and splenic antigen presenting cells, including APE-LNP demonstrating nearly tenfold more potent systemic mRNA delivery to the lungs than vivo-jetPEI. Adopting tertiary amino-alcs. to initiate ROP of lactones allows to control polymer mol. weight and obtain amino-polyesters with narrow mol. weight distribution, exhibiting batch-to-batch consistency. All of which highlight the potential for clin. translation of APEs for systemic mRNA delivery and demonstrate the importance of employing controlled polymerization in the design of new polymeric nanomaterials to improve in vivo nucleic acid delivery.
