U. published an article in 2020, the title of the article was Treating water containing elevated bromide and iodide levels with granular activated carbon and free chlorine: impacts on disinfection byproduct formation and calculated toxicity.Electric Literature of 79-07-2 And the article contains the following content:

We evaluated the efficacy of granular activated carbon (GAC) adsorption for mitigating formation of chlorine disinfection byproducts (DBPs) in water with a wide range of bromide (20-1000μg L-1) and iodide (<5-100μg L-1) concentrations GAC effectiveness was assessed by determining speciated total organic halogen (TOX), 70 DBPs, and calculated cyto- and genotoxicity. Overall, GAC treatment effectively lowered formation of TOX and the majority of targeted DBPs over the evaluated service time (>30 000 bed volumes). In the GAC influent, total organic bromine increased from 10 to 84% of TOX as bromide levels increased from 20 to 1000μg L-1. Dissolved organic carbon (DOC) removal by GAC increased the bromide-to-DOC (Br/DOC) concentration ratio in GAC effluent relative to influent. As a result, bromine incorporation into DBPs increased after GAC treatment, especially at early GAC service times and low bromide levels. Total organic iodine was <3.5% of TOX, and iodo-DBP formation was low because elevated iodide was only evaluated in the presence of high bromide and free chlorine, a scenario that favors iodate formation. Although trihalomethanes (THMs) and haloacetic acids (HAAs) consistently formed at the highest molar concentrations, they were not major contributors to calculated cyto- and genotoxicity. Principal contributors to calculated cytotoxicity included haloacetaldehydes (HALs), haloacetamides (HAMs), and haloacetonitriles (HANs), while the main drivers of genotoxicity were HALs, HAMs, HANs, and halonitromethanes (HNMs) despite lower concentrations Because bromine incorporation into DBPs increased nonlinearly with increasing Br/DOC concentration ratios, GAC more effectively controlled calculated toxicity at elevated bromide levels. Calculated cyto- and genotoxicity did not vary strongly with GAC service life, suggesting that GAC treatment can effectively lower calculated toxicity over long periods of operation. The majority of TOX remained unknown (>50%) in all samples despite the quantification of 70 DBPs targeted in this study, highlighting the need to assess toxicity associated with unknown DBPs. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Electric Literature of 79-07-2

On December 20, 2021, Zhang, Di; Dong, Shengkun; Zhang, Aihong; Chen, Li; Yu, Zhenxun; Wang, Qi; Chu, Wenhai published an article.Reference of 2-Chloroacetamide The title of the article was Catalytic hydrolysis: A novel role of zero-valent iron in haloacetonitrile degradation and transformation in unbuffered systems. And the article contained the following:

Efforts to remove highly toxic haloacetonitriles (HANs) is an important step to reduce health risks associated with disinfection by product exposure. Zero valent iron (ZVI) is a versatile material, whose reductant, sorbent and coagulant role has been well understood. However, their catalytic role is less known. In this study, the degradation and transformation of HANs in ZVI system were investigated. Significant decreases of the four HANs in ZVI system were observed, and haloacetamides and haloacetic acids (hydrolysis products of HANs) were the dominant transformation products of HANs. However dehalogenated HANs, Fe (II) and Fe (III) were rarely detected after reaction, indicating that the ZVI acted as a catalyst to promote the hydrolysis of HANs, rather than other previously reported causes (dehalogenation or redox reaction). The HAN degradation rates were dramatically affected by the initial pH, ZVI doses and initial HAN concentration Kinetic anal. indicated that HAN removal was enhanced with the increase of initial pH (5-9), ZVI doses (1-10 g/L), and initial HAN concentration (25-200μg/L). ZVI induced the transformation of HANs to haloacetamides, haloacetic acids and other de-halogenated compounds, which reduced the cytotoxicity and genotoxicity by 88% and 85%, resp. This study helped to understand the fate of HAN during the transmission in cast iron pipes, and provided a theor. foundation for future HAN control and monitoring efforts.

And the article contained the following:

The electrocatalytic activity of bismuth considered as a low-cost and green electrode material was studied in reductive dechlorination processes. Cyclic voltammetry analyses showed that the Bi electrode exhibited a high catalytic activity to reduce alachlor, a chlorinated herbicide, in the aqueous medium at different pH values. Bulk electrolyzes were performed at different potentials and pH values. Alachlor was reduced in deschloroalachlor, its dechlorinated derivative, with a high selectivity (96%) and a current efficiency of 48%. The reductive dechlorination of other chlorinated compounds with an activated carbon atom was then studied, showing that the bismuth electrode catalyzed the electroreduction of chloroacetamides, α-halocarbonyl, and α-haloallyl pollutants. Cyclic voltammetry experiments allowed us to propose a mechanism explaining the high catalytic activity of bismuth to reduce these families of compounds The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Related Products of 79-07-2

On March 15, 2022, Wang, Zheng; Li, Mengxiao; Liao, Yufeng; Pan, Yang; Shuang, Chendong; Li, Jun; Zhou, Qing; Li, Aimin published an article.Reference of 2-Chloroacetamide The title of the article was Formation of disinfection byproducts from chlorinated soluble microbial products: Effect of carbon sources in wastewater denitrification processes. And the article contained the following:

Carbon sources are crucial for biol. denitrification in wastewater treatment that significantly affects the production of soluble microbial products (SMPs), thereby affecting the formation of disinfection byproducts (DBPs) during subsequent chlorination. However, the effect of carbon sources on DBPs formation has not been studied. In this work, sodium acetate, sodium lactate, and glucose were used as carbon sources, and denitrifying SMPs derived from different carbon sources were used as DBPs precursors to investigate the formation potential (FP) of 16 carbonaceous DBPs and 19 nitrogenous DBPs. Results showed that the carbonaceous DBPs FP of SMPs derived from acetate, lactate, and glucose were 502.1-584.3, 250.3-288.9, and 374.7-439.1μg/L, resp., and the nitrogenous DBPs FP were 19.1-45.6, 12.8-21.9, and 7.9-9.0μg/L, resp. After chlorination, the genotoxicity of SMPs measured by the SOS/umu test was also evaluated with 364 ng 4-NQO/L for acetate, 212 ng 4-NQO/L for lactate, and 138 ng 4-NQO/L for glucose. Based on XPS, chem. structures of SMPs were characterized, and their relationship with DBPs FP was investigated to explain the mechanism of DBPs formation. Aromatic C and C-O were found to be the major precursor structures to form carbonaceous DBPs, and their lowest proportions in lactate-derived SMPs caused the lowest carbonaceous DBPs FP. Organic nitrogen, including aromatic N, amide/peptide N, and primary amine N, was the precursor of nitrogenous DBPs. The lowest concentration of dissolved organic nitrogen for glucose-derived SMPs caused the lowest nitrogenous DBPs FP and genotoxicity. Glucose may be a better choice among the three carbon sources in terms of reducing genotoxicity.

And the article contained the following:

Ketonic hydrolysis of 7-acetyl-4-cyano-1,6-dimethyl-6-hydroxy-8-phenyl-5,6,7,8-tetrahydro-isoquinoline-3(2H)-thione via heating with aqueous solution of potassium hydroxide resulted in both deacetylation and dehydration affording new 7,8-dihydroisoquinoline scaffold (7,8-DHISQ) I. Two simple mechanistic approaches are postulated for this synthesis. One of them was supported by converting II into I via heating with aqueous solution of potassium hydroxide. I was used as a key intermediate for synthesizing other 7,8-DHISQ’s III and IV, as well as 7,8-dihydrothienoisoquinoline. Reaction of compound II with 2-chloroacetamide by refluxing in ethanol containing sodium acetate gave 7-acetyl-1-amino-5,8-dimethyl-6-phenyl-6,7-dihydrothieno[2,3-c] isoquinoline-2-carboxamide which was converted into full aromatized pyrimidothienoisoquinoline on treatment with tri-Et orthoformate. Reaction of II with both hydrazine hydrate and hydroxylamine hydrochloride afforded tetrahydropyrazolo-isoquinoline and tetrahydroisoxazoloisoquinoline, resp. Reaction of tetrahydroisoxazoloisoquinoline with N-(4-chlorophenyl)-2-chloroacetamide produced (N-phenylcarbamoylmethylthio)tetra-hydroisoxazoloisoquinoline which was converted into tetrahydroisoxazolothieno-isoquinoline upon heating with sodium ethoxide. Also, crystal structures of compounds III and another tetrahydropyrazoloisoquinoline were determined via X-rays diffraction anal.

On April 19, 2022, Ma, Chao; Chen, Yan; Ren, Wen dong; Liu, Xing yu; Gu, Wen; Zhou, Hui li published an article.Application In Synthesis of 2-Chloroacetamide The title of the article was Performance Evaluation of Composite Antisalt Agents and the Antisalt Dynamics Simulation Mechanism. And the article contained the following:

The conventional ferrocyanide complex ([Fe(CN)6]4-) has been widely used as a scale inhibitor under mild conditions, but its oxidation at high temperature compromises the subsequent wastewater treatment processes. To conquer the inadequacies of [Fe(CN)6]4-, aminotriacetamide (NTA) was synthesized using chloroacetic acid as an initial material and its mol. structure was characterized using FT-IR spectroscopy, H-NMR, and TGA. NTA was exploited in combination with polyaspartic acid (PASP) and sodium dodecyl benzene sulfonate (SDBS) to prepare a high-performance antisalt composite, and the scaling inhibitor performance was evaluated. The results revealed that as the concentration of the antisalt composite increased from 0.5 to 1.2 weight %, the solubility and inhibition rate increased by 95.6 and 12.33%, resp., at 100°C. The results from mol. simulation evidenced that the order of binding energy between a unit mass of the salt inhibitor and sodium chloride crystal increased in the following order; SDBS > NTA > PASP. The deformation strength between the salt inhibitor and sodium chloride crystal increased as follows: NTA > PASP > SDBS. In addition, the antisalt composite mainly hampered salt precipitation through strong adsorptions arising from both the nitrogen atom of NTA and oxygen atom of SDBS with the sodium atom of sodium chloride crystals, and as a result, it not only altered the crystalline form of sodium chloride but also reduced the adsorption of sodium atoms and eventually improved the salt solubility The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Application In Synthesis of 2-Chloroacetamide
