Wang, De published the artcileTerpolymers from Borane-Initiated Copolymerization of Triphenyl Arsonium and Sulfoxonium Ylides: An Unexpected Light Emission, Formula: C19H34ClN, the publication is Angewandte Chemie, International Edition (2019), 58(19), 6295-6299, database is CAplus and MEDLINE.

The first synthesis of well-defined poly[(phenylmethylene-co-methylpropenylene)-b-methylene, [(C1-co-C3)-b-C1], terpolymers was achieved by one-pot borane-initiated random copolymerization of ω-methylallyl (C3 units, chain is growing by three carbon atoms at a time) and benzyltriphenylarsonium (C1 units, chain is growing by one carbon atom at a time) ylides, followed by polymerization of sulfoxonium methylide (C1 units). Other substituted arsonium ylides, such as prenyltriphenyl, propyltriphenyl and (4-fluorobenzyl)triphenyl can also be used instead of benzyltriphenylarsonium. The obtained terpolymers are well-defined, possess a predictable mol. weight and low polydispersity (M_n,NMR=1.83-9.68×10³ g mol^-1, D=1.09-1.22). An unexpected light emission phenomenon was discovered in these non-conjugated terpolymers, as confirmed by fluorescence and NMR spectroscopy. This phenomenon can be explained by the isomerization of the double bonds of allylic monomeric units along the chain of the terpolymers (isomerization-induced light emission).

Peyrovedin, Hamed published the artcileA global model for the estimation of speeds of sound in deep eutectic solvents, Related Products of chlorides-buliding-blocks, the publication is Molecules (2020), 25(7), 1626, database is CAplus and MEDLINE.

Deep eutectic solvents (DESs) are newly introduced green solvents that have attracted much attention regarding fundamentals and applications. Of the problems along the way of replacing a common solvent by a DES, is the lack of information on the thermophys. properties of DESs. This is even more accentuated by considering the dramatically growing number of DESs, being made by the combination of vast numbers of the constituting substances, and at their various molar ratios. The speed of sound is among the properties that can be used to estimate other important thermodn. properties. In this work, a global and accurate model is proposed and used to estimate the speed of sound in 39 different DESs. This is the first general speed of sound model for DESs. The model does not require any thermodn. properties other than the critical properties of the DESs, which are themselves calculated by group contribution methods, and in doing so, make the proposed method entirely independent of any exptl. data as input. The results indicated that the average absolute relative deviation percentages (AARD%) of this model for 420 exptl. data is only 5.4%. Accordingly, based on the achieved results, the proposed model can be used to predict the speeds of sound of DESs.

De Pascale, G. published the artcileValidation for high-throughput screening of a VanRS-based reporter gene assay for bacterial cell wall inhibitors, Application of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Journal of Applied Microbiology (2007), 103(1), 133-140, database is CAplus and MEDLINE.

The present study was undertaken to validate, for antibiotic discovery, a reporter gene assay based on a Bacillus subtilis strain expressing the Enterococcus faecium vanRS genes and a vanH-lacZ fusion, which produced β-galactosidase activity in the presence of cell wall inhibitors (CWI) and lysozyme. The reporter assay was miniaturized, automated and validated with antibiotics and tested against portions of chem. and microbial extract libraries. The assay is simple, fast and reproducible and can detect all CWI, sometimes at concentrations lower than those necessary to inhibit bacterial growth. However, some membrane-interfering compounds also generate comparable signals. While most CWI elicit a signal that is transcription-dependent and abolished in an osmoprotective medium, transcription is not required for β-galactosidase activity brought about by the membrane-interfering compounds At least two distinct mechanisms appear to lead to enzymic activity in the reporter strain. Effective counterscreens can be designed to discard the undesired classes of compounds Extensive validation is required before introducing a reporter assay in high-throughput screening. However, the ease of operation and manipulation makes the reporter assays powerful tools for antibiotic discovery.

Droge, Steven T. J. published the artcileSorption of Organic Cations to Phyllosilicate Clay Minerals: CEC-Normalization, Salt Dependency, and the Role of Electrostatic and Hydrophobic Effects, HPLC of Formula: 23616-79-7, the publication is Environmental Science & Technology (2013), 47(24), 14224-14232, database is CAplus and MEDLINE.

Sorption to the phyllosilicate clay minerals Illite, kaolinite, and bentonite has been studied for a wide variety of organic cations using a flow-through method with fully aqueous medium as the eluent. Linear isotherms were observed at concentrations below 10% of the cation-exchange capacity (CEC) for Illite and kaolinite and below 1 mmol/kg (<1% CEC) for bentonite. Sorption to clays was strongly influenced by the electrolyte composition of the eluent but with a consistent trend for a diverse set of compounds on all clays, thus allowing for empirical correction factors. When sorption affinities for a given compound to a given clay are normalized to the CEC of the clay, the differences in sorption affinities between clays are reduced to less than 0.5 log units for most compounds Although CEC-normalized sorption of quaternary ammonium compounds to clay was up to 10-fold higher than CEC-normalized sorption to soil organic matter, CEC-normalized sorption for most compounds was comparable between clays and soil organic matter. The clay fraction is thus a potentially relevant sorption phase for organic cations in many soils. The sorption data for organic cations to clay showed several regular trends with mol. structure but also showed quite a few systematic effects that we cannot explain. A model on the basis of the mol. size and charge d. at the ionized nitrogen is used here as a tool to obtain benchmark values that elucidate the effect of specific polar moieties on the sorption affinity.

J. published the artcileIon-Exchange Affinity of Organic Cations to Natural Organic Matter: Influence of Amine Type and Nonionic Interactions at Two Different pHs, Name: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Environmental Science & Technology (2013), 47(2), 798-806, database is CAplus and MEDLINE.

Sorption to standard soil organic matter (SOM) was studied for a wide variety of organic cations using a flow through method with fully aqueous medium as eluent. SOM sorption for weak bases (pK_a 4.5-7) was stronger at pH 4.5 than at pH 7, indicating that the ion-exchange affinity of the cationic species to SOM was higher than the bulk partition coefficient of corresponding neutral species to SOM. At pH 4.5-7, the effect of pH on the sorption coefficients for strong bases with pK_a >7 was small, within 0.3 log units. For cations with the mol. formula C_xH_yN, sorption was accurately predicted by a model accounting for size (increase with alkyl chain length) and type of charged group (1° amine >4° ammonium of equal size). In addition to the C_xH_yN-model, several empirical correction factors were derived from the data for organic cations with polar functional groups. Models based on K_OW or pK_a fail to explain differences in sorption affinity of the ionic species. Our data on ion-exchange affinities for 80 organic cations show many examples where specific chem. moieties, for example, CH₂-units, aromatic rings or hydroxyl groups, contribute differently to the sorption coefficient as compared to bulk partitioning data of neutral compounds Other sorption models that were evaluated to explain variation between compounds suffered from outliers of >1 log unit and did not reduce relative log mean standard errors <0.5. A wider range of sorption coefficients and more sorption data in general are required to improve modeling efforts further.

Host-guest inclusion complexes of 3 sequential cationic room temperature surface active ionic liquids, benzyltrialkylammonium chloride [(C₆H₅CH₂)N(C_nH_2n+1)₃Cl; where n = 1, 2, 4] with β-cyclodextrin in aqueous media have been studied using surface tension, conductance and NMR spectroscopy. All the studies suggested that the hydrophobic benzyl group of ionic liquids is encapsulated inside into the cavity of β-cyclodextrin and played a crucial role in supporting the formation of inclusion complexes. The variation of the thermodn. parameters with guest size, shape is used to draw inferences about contributions to the overall binding by the driving forces, viz., hydrophobic effect, steric hindrance, van der Waal force, and electrostatic force.

Tunc, Sibel published the artcileInvestigation of interactions between some anionic dyes and cationic surfactants by conductometric method, COA of Formula: C19H34ClN, the publication is Fluid Phase Equilibria (2007), 251(1), 1-7, database is CAplus.

The interactions of cationic surfactants with anionic dyes were studied by conductometric method. Benzyltrimethylammonium chloride (BTMACl), benzyltriethylammonium chloride (BTEACl) and benzyltributylammonium chloride (BTBACl) were used as cationic surfactants and indigo carmine (IC) and amaranth (Amr) were chosen as anionic dyes. The specific conductance of dye-surfactant mixtures was measured at 25, 35 and 45 °C. A decrease in measured specific conductance values of dye-surfactant mixture was caused by the formation of non-conducting or less-conducting dye-surfactant complex. The equilibrium constants, K₁, the standard free energy changes, ΔG°₁ the standard enthalpy changes, ΔH°₁ and the standard entropy changes, ΔS°₁ for the first association step of dye-surfactant complex formation were calculated by a theor. model. The results showed that the equilibrium constants and the neg. standard free energy change values for all systems decreased as temperature increased. Also these values decreased for all systems studied with increasing alkyl chains of surfactants due to the steric effect. When the equilibrium constant values, K₁, for the first association step of IC-surfactant and Amr-surfactant systems with the same surfactant were compared, the values of K₁ for IC-surfactant system were higher than that of Amr-surfactant system.

Passos, Helena published the artcileSelective Sequential Recovery of Zinc and Copper from Acid Mine Drainage, Computed Properties of 23616-79-7, the publication is ACS Sustainable Chemistry & Engineering (2021), 9(10), 3647-3657, database is CAplus.

The observed imbalance between the unsustainable consumption of available natural metal resources and finite deposits makes the recovery and recycling of metals from metal-containing wastes an imperative. Here, ionic-liquid-based aqueous biphasic systems (IL-based ABSs) are proposed as an efficient alternative for selective metal recovery from real copper acid mine drainage (AMD) effluents. ABSs composed of different ILs and Na₂SO₄ were evaluated for Zn, Al, Cu, Co, and Ni extraction from both model solutions and AMD samples. It is shown that IL composed of thiocyanate anion ([SCN]^–) presented a remarkable ability to extract metals from AMD through the formation of stable metal complexes. The addition of NaSCN to ABSs composed of tetrabutylammonium chloride ([N₄₄₄₄]Cl) allowed to mimic the use of [SCN]-based IL with addnl. advantages: tunable metal selectivity by the concentration of [SCN]^– added to the ABS and a reduction in system cost and environmental impact. Furthermore, at the [SCN]^– concentration range studied here, the formation of a hydrophobic salt composed of IL cations and metal complex anions is observed, which allows the selective extraction and recovery of transition metals in a single step. The IL-rich phase recyclability in three extraction cycles is demonstrated, showing the possibility to recover two times more Zn than with a single extraction cycle while using the same amount of IL and thiocyanate. Salt-rich phases were also recycled in a new IL-based ABS for the subsequent Cu extraction and recovery. These results allow the development of a sustainable process for the selective sequential recovery of transition metals from AMD.

M. published the artcileQuality assessment of digested sludges produced by advanced stabilization processes, Recommanded Product: N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Environmental Science and Pollution Research (2015), 22(10), 7216-7235, database is CAplus and MEDLINE.

The European Union (EU) Project Routes aimed to discover new routes in sludge stabilization treatments leading to high-quality digested sludge, suitable for land application. In order to investigate the impact of different enhanced sludge stabilization processes such as (a) thermophilic digestion integrated with thermal hydrolysis pretreatment (TT), (b) sonication before mesophilic/thermophilic digestion (UMT), and (c) sequential anaerobic/aerobic digestion (AA) on digested sludge quality, a broad class of conventional and emerging organic micropollutants as well as ecotoxicity was analyzed, extending the assessment beyond the parameters typically considered (i.e., stability index and heavy metals). The stability index was improved by adding aerobic posttreatment or by operating dual-stage process but not by pretreatment integration. Filterability was worsened by thermophilic digestion, either alone (TT) or coupled with mesophilic digestion (UMT). The concentrations of heavy metals, present in ranking order Zn > Cu > Pb > Cr ∼ Ni > Cd > Hg, were always below the current legal requirements for use on land and were not removed during the processes. Removals of conventional and emerging organic pollutants were greatly enhanced by performing double-stage digestion (UMT and AA treatment) compared to a single-stage process as TT; the same trend was found as regards toxicity reduction Overall, all the digested sludges exhibited toxicity to the soil bacterium Arthrobacter globiformis at concentrations about factor 100 higher than the usual application rate of sludge to soil in Europe. For earthworms, a safety margin of factor 30 was generally achieved for all the digested samples.

Selective oxidation of organic substrates by environment-friendly oxidizing agents is an important ingredient of the sustainable chem. industry. Here we report a comprehensive study in the field of metal peoroxocomplex catalysis for the selective liquid phase oxidation of various organic substrates. A number of well-defined bi-functional tungsten complex catalysts with tetra nuclear structure {PO4[WO(O₂)₂]₄}^3- in combination with a phase-transfer agents were synthesized. The structural properties were thoroughly studied using of IR, Raman and EXAFS spectroscopy. By combining different spectroscopy techniques were able to elucidate the effect of quaternary ammonium cations on the structural properties of the resulting peroxo complexes. The catalytic properties of these well-defined material were then evaluated in bi-phasic selective oxidation of cyclooctene, Me oleate and N-phosphonomethyliminodiacetic acid with hydrogen peroxide under mild conditions. For every substrate we were able to achieve high conversion at the selectivity towards a target product close to 100%.
