The kinetics of oxidation of propane-1,3-diol and butane-1,4-diol by N-chlorosaccharin was carried out in aqueous acetic acid medium. The reactions exhibit first order dependence in oxidant and the Michaelis-Menten’s kinetics in substrate. Increase in the concentration of added perchloric acid increases the rate of oxidation Addition of the reaction product, saccharin, exhibits retarding effect. Decrease in dielec. constant of the medium decreased the rate constant Various activation parameters have been evaluated. Mechanism proposed and the derived rate law is in agreement with the observed kinetics. In the experiment, the researchers used many compounds, for example, 2-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-dioxide (cas: 14070-51-0Electric Literature of C7H4ClNO3S).

Cyclic Trinuclear Copper(I) Complex Exhibiting Aggregation-Induced Emission: A Novel Fluorescent Probe for the Selective Detection of Gold(III) Ions was written by Li, Haozhen;Luo, Jie;Zhang, Zhi-Yin;Wei, Rong-Jia;Xie, Mo;Huang, Yong-Liang;Ning, Guo-Hong;Li, Dan. And the article was included in Inorganic Chemistry in 2022.Application of 76-83-5 This article mentions the following:

Coordination complexes with aggregation-induced-emission (AIE) behavior has drawn much attention because of their promising applications. Conventionally, the AIE-active metal-organic complexes are prepared from an AIE-active organic ligand, and the construction of such coordination complexes from aggregation-caused-quenching (ACQ) ligands is still challenging. Herein, we have synthesized two new cyclic trinuclear complexes (CTCs), namely, 1 and 2, from copper(I) and silver(I) and a ACQ ligand [4-(3,5-dimethyl-1H-pyrazol-4-yl)benzaldehyde, HL]. (1) Exhibited AIE behavior, and the emission intensity is enhanced ~20 times when it aggregates, which can be attributed to its tight packing and multiple intermol. hydrogen bonds that restrained the intramol. rotation, as confirmed by single-crystal X-ray diffraction anal. On the other hand, (2) displayed ACQ effects, and the emission intensity is decreased ~5 times when it aggregates. This ACQ behavior of 2 is related to its loose packing and free rotation of the ligand in crystals, resulting in nonradiative decay and fluorescence quenching. Interestingly, the CTCs 1 and 2 both exhibited a good affinity to gold(III) ions, allowing selective detection and sensing of gold ions. More importantly, the 2 shows a good limit of detection (3.28μmol/L) and an ultrafast responsive time (~2 s). Our studies pave a new route to designing novel AIE-active coordination complexes and further exploring the functionality of CTCs. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Application of 76-83-5).

(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Application of 76-83-5

Highly efficient manganese (III) oxide submerged catalytic ceramic membrane for nonradical degradation of emerging organic compounds was written by Chen, Li;Maqbool, Tahir;Fu, Wanyi;Yang, Yulong;Hou, Congyu;Guo, Jianning;Zhang, Xihui. And the article was included in Separation and Purification Technology in 2022.Synthetic Route of C13H9Cl3N2O This article mentions the following:

In this study the performance of catalytic ceramic membranes in activating peroxymonosulfate (PMS) for the degradation of emerging organic contaminants (EOCs) was investigated. The catalytic ceramic membrane (MnCM) integrated with Mn₂O₃ nanoparticles was fabricated by a solid-state sintering method. Phys. and chem. properties of MnCM were characterized by SEM/EDX, XRD, BET, AFM and XPS. The MnCM/PMS system has shown excellent decontamination efficiencies (81-97% removal) for different EOCs. Acetaminophen (APAP) has been efficiently degraded by MnCM/PMS in different real water matrixes and harsh water conditions. Based on results of quenching experiments and ESR (EPR) analyses, non-radical pathway with singlet oxygen (¹O₂) was the dominant ROS for the degradation of EOCs. The membrane pores in active layer acted as micro-reactors for the interaction among active sites, PMS, and EOCs. The MnCM/PMS system showed outstanding catalytic stability with high mineralization (TOC removal of ∼ 65%) and negligible leaching of the manganese (1.3-1.5μg/L) in permeate. Hydroxylation and C-N bond cleavage were found to be the main degradation pathways of APAP by MnCM/PMS system. The MnCM prepared in this study with excellent performance could be a way forward for applications at large-scale or full-scale water systems suffering from heavy loads or trace amount of refractory organic compounds In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Synthetic Route of C13H9Cl3N2O).

And the article was included in Journal of Applied Polymer Science in 2022.Category: chlorides-buliding-blocks This article mentions the following:

A superwetting forward osmosis membrane was prepared by grafting a zwitterion (2-methacryloyloxyethyl phosphorylcholine, MPC) onto the polyamide membrane layer via atom transfer radical polymerization (ATRP) to enhance antifouling property. The modification of the hydrophilic layer was confirmed by the characterization including Fourier-transform IR spectroscopy (FTIR), XPS, and contact angle goniometer. Moreover, membrane antifouling performance was evaluated by dynamic membrane fouling test using bovine-serum-albumin (BSA) and sodium alginate (SA). The grafted membranes not only showed high fouling resistance after being exposed to up to 500 ppm SA for 10 h, but also demonstrated excellent water flux recovery with the presence of up to 1000 ppm BSA, which was significantly improved as compared to the unmodified membrane. Robust hydration layer formed by the grafted zwitterion polymer could act as a phys. and energy barrier preventing attachment of organic foulants on the membrane surface, thus significantly improving membrane fouling resistance.

A series of 2,6,9-trisubstituted purine derivatives I (R¹ = i-Pr, Bu, i-Bu, i-Pe, Hx, Pe; R² = H, OMe) have been synthesized and investigated for their potential role as antitumor agents. Twelve compounds were obtained by a three step synthetic procedure using microwave irradiation in a pivotal step. All the synthesized compounds were evaluated in vitro to determine their potential effect on cell toxicity by the MTT method and flow cytometry anal. on four cancer cells lines and Vero cells.

Hybrid nanofiltration thin film hollow fiber membranes with adsorptive supports containing bentonite and LDH nanoclays for boron removal was written by Ghiasi, Sanaz;Mohammadi, Toraj;Tofighy, Maryam Ahmadzadeh. And the article was included in Journal of Membrane Science in 2022.Electric Literature of C9H3Cl3O3 This article mentions the following:

This study focused on removal of boron from water via hybrid nanofiltration (NF) thin film composite (TFC) hollow fiber (HF) membranes. To do so, nanocomposite polyvinyl chloride (PVC) HF membranes containing bentonite and layered double hydroxide (LDH) nanoparticles as natural and synthetic adsorbents were fabricated as the adsorptive support layers with high efficiency in boron removal. The phase inversion behavior of dope solutions and mech. strength of the adsorptive nanocomposite PVC HF membranes were investigated and the results showed that LDH interacts better with PVC polymeric chains than bentonite. It was found that LDH with smaller pores and better adsorption capability in comparison with bentonite results in more hydrophilic membranes with better performance. On the other hand, bentonite tends to become agglomerated at above 1.5 wt%. Moreover, the fabricated membranes containing LDH have lower MWCO and more uniform pore size distribution which make them better options as support for the TFC layer formation to fabricate NF TFC membranes. The selective TFC layer was then fabricated via interfacial polymerization of m-phenylenediamine (MPD) and 1,3,5- benzenetricarbonyl trichloride (TMC) on the outer layer of the nanocomposite PVC HF membranes. Boron removal, and recovery and reusability of the fabricated NF TFC membranes were investigated by Na₂CO₃ solution It was found that the NF TFC membranes containing LDH with boron removal of more than 83.6% and water flux of 16.1 L/m2.h at 4 bar operational pressure exhibit better performance than the NF TFC membranes containing bentonite. In the experiment, the researchers used many compounds, for example, Trimesoylchloride (cas: 4422-95-1Electric Literature of C9H3Cl3O3).

Design and Optimization of an Acyclic Amine Series of TRPV4 Antagonists by Electronic Modulation of Hydrogen Bond Interactions was written by Patterson, Jaclyn R.;Terrell, Lamont R.;Donatelli, Carla A.;Holt, Dennis A.;Jolivette, Larry J.;Rivero, Ralph A.;Roethke, Theresa J.;Shu, Arthur;Stoy, Patrick;Ye, Guosen;Youngman, Mark;Lawhorn, Brian G.. And the article was included in Journal of Medicinal Chemistry in 2020.Formula: C7H3Cl2F3O2S This article mentions the following:

Investigation of TRPV4 as a potential target for the treatment of pulmonary edema associated with heart failure generated a novel series of acyclic amine inhibitors displaying exceptional potency and PK properties. The series arose through a scaffold hopping approach, which relied on use of an internal H-bond to replace a saturated heterocyclic ring. Optimization of the lead through investigation of both aryl regions revealed approaches to increase potency through substituents believed to enhance sep. intramol. and intermol. H-bond interactions. A proposed internal H-bond between the amine and neighboring benzenesulfonamide was stabilized by electronically modulating the benzenesulfonamide. In the aryl ether moiety, substituents para to the nitrile demonstrated an electronic effect on TRPV4 recognition. Finally, the acyclic amines inactivated CYP3A4 and this liability was addressed by modifications that sterically preclude formation of a putative metabolic intermediate complex to deliver advanced TRPV4 antagonists as leads for discovery of novel medicines. In the experiment, the researchers used many compounds, for example, 4-Chloro-2-(trifluoromethyl)benzene-1-sulfonyl chloride (cas: 54090-42-5Formula: C7H3Cl2F3O2S).

Elastic, tough and switchable swelling hydrogels with high entanglements and low crosslinks for water remediation was written by Li, Daikun;Zhan, Wei;Zuo, Wei;Li, LiPin;Zhang, Jun;Cai, Guiyuan;Tian, Yu. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Recommanded Product: 61-73-4 This article mentions the following:

Developing hydrogel adsorbents with both high mech. property and high adsorption capacity is a big challenge. At the same time, the swelling-adsorption is in conflict. Swelling expands the polymer network and facilitates the exposure of adsorption sites and the diffusion of pollutants. On the other hand, swelling causes the hydrogel to increase in volume and soften, which increases the difficulty of operation and regeneration. Hence, we promote a method of preparation advanced hydrogel adsorbent by high entanglements and low crosslinks. The entanglements work as addnl. crosslinks, reducing swelling and making the hydrogel tough. Unlike crosslinks, entanglements are like springs, which are flexible and can efficiently transmit and store stress. Therefore, highly entangled hydrogel exhibits high elasticity, low hysteresis, and good fatigue resistance. Abundant carboxyl functional groups are introduced by copolymerizing acrylic acid. The carboxyl groups are not only sites for adsorbing cationic pollutants, but also a smart switch for regulation of swelling. When adsorbing pollutants, the carboxyl groups are deprotonated, and the flexible entanglements allow large swelling of the hydrogel while maintaining good rigidity, which efficiently facilitates adsorption. Compared with highly crosslinked hydrogel with similar polymer content and carboxyl abundance, the adsorption capacity and rate of highly entangled hydrogel increased by more than ten times. While regeneration, the highly entangled hydrogel de-swells efficiently under the tension of entanglements, significantly improving the operability of regeneration. This study provides a novel strategy for developing smart hydrogel adsorbent. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Recommanded Product: 61-73-4).
