And the article contained the following:

The development of a facile approach to fabricate anion exchange membranes (AEMs) with efficient ionic transport and desirable stabilities (mech. and dimensional) for various applications is meaningful. In this work, a two-step strategy for the preparation of AEMs with 3D network structure, via crosslinking reaction between 2-chloroacetamide (CAA) modified poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and N,N,N’,N’-tetramethyl-1,4-diaminobutane (TMDAB) has been reported. The as-prepared AEMs with ion-exchange capacity (IEC) in the range of 1.38-1.84 mmol g-1, exhibit the much lower water uptake (13.14-22.45%, 80°C) relative to the un-crosslinked AEM (35.89%, 80°C). In addition, due to the presence of fluorine-based 3D network structure, the as-prepared AEMs show much enhanced mech. and thermal stability in comparison with the un-crosslinked AEM. In the electrodialysis (ED) application, the optimized AEM shows the higher current efficiency (78.6%) and lower energy consumption (2.01 kWh kg-1 NaCl) than those of com. AEM AEM-Type II (76.4%; 2.26 kWh kg-1), resp., within 150 min of operation interval. The proposed facile fabrication protocol and the better-performance of optimized PVDF-HFP -based AEM demonstrate the potential ED application. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Application In Synthesis of 2-Chloroacetamide

On March 31, 2020, Kim, Da-Hye; Park, Chang Gyun; Kim, Young Jun published an article.Formula: C2H4ClNO The title of the article was Characterizing the potential estrogenic and androgenic activities of two disinfection byproducts, mono-haloacetic acids and haloacetamides, using in vitro bioassays. And the article contained the following:

Exposure to disinfection byproducts (DBPs) is potentially related to cytotoxic, genotoxic, mutagenic, and tumorigenic effects in humans, in addition to their adverse effects on the environment. However, their impacts on endocrine disruption, especially reproductive toxicity, remain largely unknown. In this study, the estrogenic and androgenic activities of DBPs and corresponding antagonistic activities were investigated using a yeast-based reporter assay, focusing on haloacetic acids and haloacetamides. We also examined the cytotoxicity of DBPs and mechanisms of antagonistic activities. Of the DBPs assayed, iodoacetamide (IAM) and bromoacetamide (BAM) were the most cytotoxic, with LC50 values of 0.0462 and 0.0537 mM, resp., followed by chloroacetic acid (CAA; LC50 = 4.87 mM) and chloroacetamide (CAM; LC50 = 5.28 mM). Iodoacetic acid (IAA) and bromoacetic acid (BAA) were the least cytotoxic, with LC50 values of 5.52 and 6.35 mM, resp. IAA (EC10 = 0.00573 mM; EC50 = 0.0215 mM) exhibited most potent estrogenic activity, and CAA (EC10 = 0.0434 mM) and BAM (EC10 = 0.0150 mM) showed weak estrogenic and androgenic activities, resp. By contrast, IAM exhibited anti-estrogenic effects. These results suggest that DBPs interact with hormone receptors.

Chau, Nguyen Dang Giang; Van Hop, Nguyen; Long, Hoang Thai; Duyen, Ngo Thi My; Raber, Georg published an article in 2020, the title of the article was Multi-residue analytical method for trace detection of new-generation pesticides in vegetables using gas chromatography-tandem mass spectrometry.Formula: C2H4ClNO And the article contains the following content:

A GC-MS/MS method with low solvent consumption and easy operation was developed to simultaneously determine ten new-generation pesticides, namely fenobucarb, acetochlor, pretilachlor, fipronil, trifloxystrobin, fluazifop-p-Bu, isoprothiolane, tebuconazole, cypermethrin and difenoconazole in leafy vegetables. Influences from ultrasonic sample extraction and the clean-up steps to reduce matrix effects were investigated. Under suitable conditions, good linearity (deviation of back calculated concentration from true concentration lower than 20%) was achieved for all studied pesticides; the method detection limits (MDLs) ranged from 1.4 to 3.6 ng g-1 wet weight For mustard green and green onion the method yielded good recoveries at two spiking levels (201 and 100 ng g-1) ranging from 80% to 111% (n = 5). The repeatability, expressed as relative standard deviation (RSD), was lower than 11% (n = 5). The method was successfully used to quantify pesticide residues in 207 vegetable samples (green onions, mustard greens, and lettuce) collected in Thua Thien Hue and Quang Binh Provinces, Central Vietnam. The insecticide cypermethrin was found at critical levels in 98% of the vegetable samples. Green onions had high pesticide residues with a significant number of samples containing pesticides at concentrations exceeding the maximum residue levels (MRLs). The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Formula: C2H4ClNO

Mohareri, Mohammad Moein; Ghaffari, Mehdi; Sattarzadeh, Elham; Kakaei, Saeed published an article in 2021, the title of the article was Preparation and application of Fe3O4@Acetamidoxanthate as a unique nanosorbent in heavy metal removing.Computed Properties of 79-07-2 And the article contains the following content:

Chelating agents are one of the most important substances in metal extraction, but separation is the main problem in the use of these agents as an adsorbent. After the adsorption of metals by an external magnet, magnetic NPs provide the possibility of easy collecting and isolating the adsorbent nanomaterial for many applications. Given the immense importance of magnetic NPs, there has been widespread interest in accessing the above adsorbent. In the present study, an attempt was made to synthesize acetamido xanthate which was coupled to NPs and has the potential to be used as a nano-adsorbent for the removal of heavy metals. This novel nano sorbent was characterized by SEM (SEM), Fourier transforms IR (FT-IR), and NMR (NMR) spectroscopy. The effect of some parameters such as temperature, time, pH, and the amount of adsorbent on the extraction reaction was investigated. The optimized condition for extraction of cerium was temperature of 30°C, pH=8, reaction time of 45 min using 7.5mg of the prepared nanosorbent, that in such condition the yield of reaction achieved up to 97%. The prepared adsorbent showed high efficiency in the adsorption of heavy metals specifically. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Computed Properties of 79-07-2

On April 30, 2022, Tong, Ruoming; Fu, Rui; Yang, Zhe; Jiang, Yuanxing; Jiang, Kun; Sun, Xuhui published an article.Computed Properties of 79-07-2 The title of the article was Efficient degradation of sulfachloropyridazine by sulfite activation with CuO-Al2O3 composites under neutral pH conditions: Radical and non-radical. And the article contained the following:

In this work, CuO-Al2O3 composites were synthesized at higher temperatures to control the leaching of metal ions, which can activate sulfite (S(IV)) to degrade organic contaminants by generating reactive oxygen species (ROSs). The synthesized catalysts were characterized by X-ray diffraction, SEM, high-resolution transmission electron microscopy, Brunauer-Emmett-Teller, Raman spectroscopy, and Fourier transform IR spectrophotometry. Sulfachloropyridazine (SCP) was almost completely removed (>99%) at pH 6.8, and the leaching amount of Cu accounted for 0.027% of the total amount of Cu after the reaction. Notably, singlet oxygen (1O2) was found for the first time in the activated sulfite system, which removed organic pollutants together with sulfate (SO4·- ) and hydroxyl (·OH) radicals. And Al2O3 plays an important role in the catalyst, including anti-sintering, reducing the leaching of copper ions, and promoting the generation of oxygen vacancies. Based on the types of ROSs and XPS results, a possible ROSs generation mechanism was proposed. In addition, the stability of the catalyst and the effect of different factors on the degradation of SCP, including operating parameters and water quality, were further investigated. The intermediates were detected by using gas chromatog.-mass spectrometry and a developmental toxicity assessment of the intermediates was defined based on the Toxicity Estimation Software Tool (TEST). Overall, this paper not only provides a new strategy for sulfite activation but also promotes more attention to non-radical processes in activated sulfite systems. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Computed Properties of 79-07-2

Zhang, Chuhui; Maness, J. Clark; Cuthbertson, Amy A.; Kimura, Susana Y.; Liberatore, Hannah K.; Richardson, Susan D.; Stanford, Benjamin D.; Sun, Mei; Knappe, Detlef R. 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.

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.
