Salamanca, Monica published the artcileEcological Risk Evaluation and Removal of Emerging Pollutants in Urban Wastewater by a Hollow Fiber Forward Osmosis Membrane, Formula: C12H15ClO3, the publication is Membranes (Basel, Switzerland) (2022), 12(3), 293, database is CAplus and MEDLINE.

Forward osmosis (FO) is a promising technol. for the treatment of urban wastewater. FO can produce high-quality effluents and preconc. urban wastewater for subsequent anaerobic treatment. This membrane technol. makes it possible to eliminate the pollutants present in urban wastewater, which can cause adverse effects in the ecosystem even at low concentrations In this study, a 0.6 m² hollow fiber aquaporin forward osmosis membrane was used for the treatment of urban wastewater from the Valladolid wastewater treatment plant (WWTP). A total of 51 Contaminants of Emerging Concern (CECs) were investigated, of which 18 were found in the target urban wastewater. They were quantified, and their ecotoxicol. risk impact was evaluated. Different salts with different concentrations were tested as draw solutions to evaluate the membrane performances when working with pretreated urban wastewater. NaCl was found to be the most appropriate salt since it leads to higher permeate fluxes and lower reverse saline fluxes. The membrane can eliminate or significantly reduce the pollutants present in the studied urban wastewater, producing water without ecotoxicol. risk or essentially free of pollutants. In all cases, good recovery was achieved, which increased with mol. weight, although chem. and electrostatic interactions also played a role.

Perez-Lemus, N. published the artcileAnalysis of 60 pharmaceuticals and personal care products in sewage sludge by ultra-high performance liquid chromatography and tandem mass spectroscopy, Related Products of chlorides-buliding-blocks, the publication is Microchemical Journal (2022), 107148, database is CAplus.

This paper presents a comparison of three different anal. proposals for the determination of 60 pharmaceuticals and personal care products (PPCPs) in solid urban sewage sludge. Two fast sample pretreatments, i.e., online solid-phase-extraction (online SPE) and direct injection (DI), were tested against the conventional offline solid phase extraction (offline SPE). In all cases, subsequently, extracts underwent ultra-high-performance-liquid chromatog. coupled to tandem-mass-spectrometry (UHPLC-MS/MS), simultaneously operating in both pos. and neg. electrospray ionization (ESI) mode. In addition, as solid matrixes, clean-up steps were necessarily preceded by ultra-sound-assisted extraction (UAE) in all cases. Matrix-matched quantification was combined with internal standard providing high reliability to all three approaches. Best performance was observed for the fully automatized and non-pretreated DI method, showing limits of detection below 30 ng g-1 for many of the target compounds, and recoveries between 80 and 120%. Finally, the best working method was validated and applied to the anal. of PPCPs in different dewatered digested sludge samples from the wastewater treatment plant (WWTP) in Valladolid (Spain). Acetaminophen was found at concentrations above 1,000 ng g-1.

Xu, Peng published the artcileRadical Decarboxylative Carbometalation of Benzoic Acids: A Solution to Aromatic Decarboxylative Fluorination, SDS of cas: 116850-28-3, the publication is Journal of the American Chemical Society (2021), 143(14), 5349-5354, database is CAplus and MEDLINE.

Abundant aromatic carboxylic acids exist in great structural diversity from nature and synthesis. To date, the synthetically valuable decarboxylative functionalization of benzoic acids is realized mainly by transition-metal-catalyzed decarboxylative cross couplings. However, the high activation barrier for thermal decarboxylative carbometalation that often requires 140°C reaction temperature limits both the substrate scope as well as the scope of suitable reactions that can sustain such conditions. Numerous reactions, for example, decarboxylative fluorination that is well developed for aliphatic carboxylic acids, are out of reach for the aromatic counterparts with current reaction chem. Here, we report a conceptually different approach through a low-barrier photoinduced ligand to metal charge transfer (LMCT)-enabled radical decarboxylative carbometalation strategy, which generates a putative high-valent arylcopper(III) complex, from which versatile facile reductive eliminations can occur. We demonstrate the suitability of our new approach to address previously unrealized general decarboxylative fluorination of benzoic acids.

Huang, Wenxiu published the artcileFunctional polyimides based on diamine containing diarylethylene moieties and their photochromic mechanism studies, SDS of cas: 219537-97-0, the publication is Polymer Chemistry (2020), 11(41), 6701-6707, database is CAplus.

To expand the existing application conditions of photochromic polymers and enhance the tolerance of photochromic polymer electronic devices in extreme environments, a diamine monomer DTEDA bearing the diarylethylene (DTE) moiety was synthesized and polymerized with com. available dihydrides to afford three polyimides (PIs, named DTEODPI, DTE6FPI and DTEHPMPI) through chem. imidization. These PIs realized reversible photo-triggered isomerization both in solution and in film state, with solution photoluminescence “on/off” effects. Semi-aromatic DTEHPMPI showed the largest contrast of color and fastest light response due to its local excited (LE) state. This research provides a simple method to prepare photochromic polymer materials with excellent comprehensive properties.

Yang, Shuqing published the artcileOligomerization of isobutene catalyzed by AlCl₃ ionic liquids, HPLC of Formula: 23616-79-7, the publication is Shiyou Lianzhi Yu Huagong (2012), 43(5), 14-18, database is CAplus.

AlCl₃ ionic liquids having various cations and anions were synthesized. Tests for oligomerization of isobutene catalyzed by various AlCl₃ ionic liquids were conducted in an autoclave, and the effect of reaction temperature, reaction time and stirring speed was studied. Exptl. results indicated that these AlCl₃ ionic liquids exhibited good catalytic performance in isobutene oligomerization with conversion of isobutene over 95%. For ionic liquids synthesized by AlCl₃ and (C₂H₅)₃NHCl, when the mole ratio of AlCl₃ to(C₂H₅)₃NHCl was below 1, the AlCl₃ ionic liquid was inactive to isobutene oligomerization. When the mole ratio of AlCl₃ to(C₂H₅)₃NHCl was 1, the ionic liquid exhibited certain catalytic activity and its selectivity to dimers and trimers was good. When the mole ratio of AlCl₃ to (C₂H₅)₃NHCl was above 1, these ionic liquids could effectively catalyze oligomerization reactions, the conversion of isobutene reached more than 95%, yet the selectivity to dimers and trimers declined and the product distributions were continuous with certain amount of cracking byproducts. The optimal reaction conditions were as follows: a reaction temperature of 80°C, a reaction time of 30 min and stirring speed of 1300 r/min.

Chen, Shuqing published the artcileThe Discovery of a Palladium(II)-Initiated Borono-Catellani Reaction, Related Products of chlorides-buliding-blocks, the publication is Angewandte Chemie, International Edition (2018), 57(24), 7161-7165, database is CAplus and MEDLINE.

Reported is a novel palladium(II)-initiated Catellani-type reaction that uses widely accessible aryl boronic acids as the substrates instead of aryl halides, thereby greatly expanding the existing scope of this powerful transformation. This borono-Catellani reaction was promoted by cooperative catalysis between Pd(OAc)₂ and the inexpensive 5-norbornene-2-carbonitrile. Practicality is the striking feature of the reaction: it is run open to air at ambient temperature and no phosphine ligand is needed. This mild, chemoselective, and scalable protocol is compatible with a large range of readily available functionalized aryl boronic acids and bromides, as well as terminating olefins (50 examples, 39-97% yields). Moreover, the orthogonal reactivity between the borono-Catellani and classical Catellani reaction was demonstrated. This work is expected to open new avenues for developing novel Catellani-type reactions.
