Recovery of iridium by solvent extraction and direct electrodeposition using phosphonium-based ionic liquids was written by Matsumiya, Masahiko;Kinoshita, Ryoma;Tsuchida, Yusuke;Sasaki, Yuji. And the article was included in Journal of the Electrochemical Society in 2021.SDS of cas: 5137-55-3 The following contents are mentioned in the article:

The extraction behavior of Ir(IV) in a phosphonium-based ionic liquid (IL) system, triethyl-n-pentyl phosphonium bis(trifluoromethyl-sulfonyl)amide ([P2225][NTf2]), was studied using an amine extractant. The electrochem. behavior of the extracted Ir(IV) species in [P2225][NTf2] during electrodeposition was studied. Voltammetry-based electrochem. anal. revealed that the reduction of Ir(IV) proceeded via an intermediate Ir(III) species in two steps, namely, Ir(IV) + e- → Ir(III) and Ir(III) + 3e- → Ir(0). Diffusion coefficients of the extracted Ir(IV) species in the IL were determined at 298-373 K using semi-integral and semi-differential analyses, and values obtained from the two analyses were consistent with each other. Also, consecutive solvent extraction and electrodeposition of Ir metal in the IL bath were performed for 10 cycles. The entire Ir electrodeposit was in the metallic state, as is evident from the 4f7/2 spectrum obtained by XPS. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3SDS of cas: 5137-55-3).

N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).SDS of cas: 5137-55-3

Isoprene Soya Diels-Alder Adduct and Epoxidation for Photopolymerization was written by Ren, Xiaofeng;Xu, Tong;Thomas, Jomin;Soucek, Mark D.. And the article was included in Macromolecular Chemistry and Physics in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

A novel cyclohexane derivatized soybean oil (CSO) is synthesized by Diels-Alder cycloaddition of soybean oil with isoprene. Then, the epoxidized cycloaliphatic soybean oil (ECSO) is prepared via epoxidation of CSO. For comparison purpose, norbornylized soybean oil (NSO) and epoxy norbornane soybean oil (ENSO) are synthesized. The CSO, ECSO, NSO, and ENSO are characterized by ¹H NMR, ¹³C NMR, gradient heteronuclear single quantum correlation (gHSQC) 2D NMR, and mass spectroscopy. The epoxidized soybean oil (ESO), ECSO, and ENSO are photopolymerized using UV-light, and the kinetics of the photocuring reactions is evaluated by real-time Fourier transform IR (FT-IR) and photo-differential scanning calorimetry (DSC). Real-time FT-IR and photo-DSC indicate the improved reactivity of ECSO and ENSO compared to ESO. It is found that the curing rate and final conversion of novel developed ECSO is higher than ESO, but lower than ENSO.

Reinforcing the supply chain of umifenovir and other antiviral drugs with retrosynthetic software was written by Lin, Yingfu;Zhang, Zirong;Mahjour, Babak;Wang, Di;Zhang, Rui;Shim, Eunjae;McGrath, Andrew;Shen, Yuning;Brugger, Nadia;Turnbull, Rachel;Trice, Sarah;Jasty, Shashi;Cernak, Tim. And the article was included in Nature Communications in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

The global disruption caused by the 2020 coronavirus pandemic stressed the supply chain of many products, including pharmaceuticals. Multiple drug repurposing studies for COVID-19 are now underway. If a winning therapeutic emerges, it is unlikely that the existing inventory of the medicine, or even the chem. raw materials needed to synthesize it, will be available in the quantities required. Here, we utilize retrosynthetic software to arrive at alternate chem. supply chains for the antiviral drug umifenovir, as well as eleven other antiviral and anti-inflammatory drugs. We have exptl. validated four routes to umifenovir and one route to bromhexine. In one route to umifenovir the software invokes conversion of six C-H bonds into C-C bonds or functional groups. The strategy we apply of excluding known starting materials from search results can be used to identify distinct starting materials, for instance to relieve stress on existing supply chains.

CaF₂ nanocrystals doped with Yb³⁺, Tb³⁺ and Li⁺ ions were investigated to study the correlation between their structural, electronic and up-conversion emission properties. The role of interstitial and substitutional Li⁺ ions in enhancing the up-conversion intensities were discussed. Evidence of Li⁺ at both interstitial and substitutional sites was provided by X-ray diffraction and XPS. The diffuse reflection spectra confirmed that the dopants were successfully incorporated. Up-conversion emission spectra under 980 nm excitation wavelength revealed the vital role of Li⁺ ions in enhancing both blue and green emission. The results reported during this investigation are expected to provide better understanding of the mechanism involved in enhancing the up-conversion emission in many Yb³⁺-Tb³⁺ co-doped fluoride materials due to Li⁺ ions doping. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Electric Literature of ClLi).

ZIF-8 penetrating composite membrane for ion sieving was written by Qi, Chenyang;Li, Jiang;Shi, Yayun;Zhang, Bowen;Chen, Tongdan;Wang, Chen;Liu, Qihang;Yang, Xiaowei. And the article was included in Journal of Solid State Chemistry in 2022.Quality Control of Lithium chloride The following contents are mentioned in the article:

Ion sieving is essential for biol. systems and membrane-based applications. At present, metal-organic framework (MOF) membranes are of great interest for use in ion separation, but it remains a great challenge to design high quality MOF membranes with a simple preparation process and desirable ion selectivity. Herein we fabricate a MOF composite membrane, containing highly penetrated ZIF-8 channels. The ZIF-8 channels are the dominant pathways for ion transport and display a good Li⁺/Mg²⁺ sieving performance (Li⁺/Mg²⁺ = 6.1). The simulation reveals that the Li⁺/Mg²⁺ selectivity is associated with the significant disparity of transport energy barrier between them, which is caused by the different extent of ion dehydration in angstrom-scale ZIF-8 channels. This work provides an effective strategy to develop ionic sieving membranes based on penetrating MOF channels for lithium extraction This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Quality Control of Lithium chloride).

Monte carlo simulations and experiments of all-silica zeolite LTA assembly combining structure directing agents that match cage sizes was written by Bores, Cecilia;Luo, Song;David Lonergan, J.;Richardson, Eden;Engstrom, Alexander;Fan, Wei;Auerbach, Scott M.. And the article was included in Physical Chemistry Chemical Physics in 2022.Formula: C4H12ClN The following contents are mentioned in the article:

The effect is investigated of organic structure-directing agents (OSDAs) on the formation rates of all-silica zeolite LTA using both simulations and experiments, to shed light on the crystallization process. Syntheses are compared using one OSDA with a diameter close to the size of the large cavity in LTA and two OSDAs of diameters matching the sizes of both the small and large LTA cavities. Reaction-ensemble Monte Carlo (RxMC) simulations predict a speed up of LTA formation using two OSDAs matching the LTA pore sizes; this qual. result is confirmed by exptl. studies of crystallization kinetics, which find a speedup in all-silica LTA crystallization of a factor of 3. Analyses of simulated rings and their Si-O-Si angular energies during RxMC crystallizations show that all ring sizes in the faster crystallization exhibit lower angular energies, on average, than in the slower crystallization, explaining the origin of the speedup through packing effects.

In the present study, novel ionic liquid-impregnated chitosan hydrogel beads (CS-TCMA) were fabricated via the reaction of tricaprylmethylammonium chloride (TCMA, Aliquat-336) with the chitosan’s amino groups. They were used for the fast adsorption of Tetracycline (TC), as a pharmaceutical compound model, from aqueous solution It was found that the impregnation of TCMA greatly improved the adsorption behavior of chitosan toward TC. The optimum adsorbent was determined to be 3 mg/ L in a wide pH range of 5-11. It was a fast process, with a 90% removal efficiency in <45 min. The adsorption kinetic of TC on the CS-TCMA was well described by the pseudo-first-order model and intra-particle diffusion model. The adsorption also obeyed the Langmuir adsorption isotherm model and the maximum adsorption capacity obtained was 22.42 mg/g at 45°C. The thermodn. study also revealed the endothermic nature of the process. The adsorption mechanism was also studied.

Organic getters are often introduced into sealed systems to remove the excessive reactive hydrogen gas. In this work, the formable graphene aerogel hydrogen getters are prepared by integrating the alkyne-containing mols.(e.g., DEB) into the palladium-loaded three-dimensional layered porous graphene aerogel (Pd-GA).
