Wang, Gang published the artcileLiquid-Phase Epoxidation of Propylene with H₂O₂ over TS-1 Zeolite: Impurity Formation and Inhibition Study, Safety of 2-Aminobutan-1-ol, the publication is Industrial & Engineering Chemistry Research (2021), 60(32), 12109-12122, database is CAplus.

The liquid-phase epoxidation of propylene with H₂O₂ over titanium silicalite-1 (TS-1) zeolite was investigated in detail with a focus on the formation and inhibition of various trace impurities like acetaldehyde, propionaldehyde, acetone, hydroxyacetone, acetals, esters, etc. The results showed that the formation of trace impurities involved the transformation of propylene oxide (PO), its oxidation/isomerization/ring-opening (solvolysis and hydrolysis) byproducts, methanol solvent, and even propylene. Roughly speaking, the epoxidation conditions, viz., low temperature, short residence time, and slightly alk. reaction medium, that are beneficial to suppress the ring-opening byproducts of PO, were seen facilitating the inhibition of trace impurities as well. To lower the trace impurities via modification of the TS-1 catalyst, the hydrothermal modification of TS-1 with organic amines such as amino-2-propanol (MIPA) was attempted and its effectiveness was demonstrated. The TS-1 zeolite suitably modified by MIPA exhibited abundant Ti-OH groups (3672 cm^-1) together with remarkably decreased PO adsorption.

Yue, Rong published the artcileInsight into enzyme-catalyzed aziridine formation mechanism in ficellomycin biosynthesis, Safety of 2-Aminobutan-1-ol, the publication is European Journal of Medicinal Chemistry (2020), 112639, database is CAplus and MEDLINE.

Ficellomycin is an aziridine-containing antibiotic, produced by Streptomyces ficellus. Based on the newly identified ficellomycin gene cluster and the assigned functions of its genes, a possible pathway for aziridine ring formation in ficellomycin was proposed, which is a complex process involving at least 3 enzymic steps. To obtain support for the proposed mechanism, the targeted genes encoding sulfate adenylyltransferase, adenylsulfate kinase, and a putative sulfotransferase were resp. disrupted and the subsequent anal. of their fermentation products revealed that all the three genes were involved in aziridine formation. To further confirm the mechanism, the key gene encoding a putative sulfotransferase was over expressed in Escherichia coli Rosseta (DE3). Enzyme assays indicated that the expressed sulfotransferase could specifically transfer a sulfo group from 3′-phosphoadenosine-5′-phosphosulfate (PAPS) onto the hydroxyl group of (R)-(-)-2-pyrrolidinemethanol. This introduces a good leaving group in the form of the sulfated hydroxyl moiety, which is then converted into an aziridine ring through an intramol. nucleophilic attack by the adjacent secondary amine. The sulfation/intramol. cyclization reaction sequence maybe a general strategy for aziridine biosynthesis in microorganisms. Discovery of this mechanism revealed an enzyme-catalyzed route for the synthesis of aziridine-containing reagents and provided an important insight into the functional diversity of sulfotransferases.

Ho, Steven Sai Hang published the artcileSeasonal behavior of water-soluble organic nitrogen in fine particulate matter (PM_2.5) at urban coastal environments in Hong Kong, Quality Control of 96-20-8, the publication is Air Quality, Atmosphere & Health (2019), 12(4), 389-399, database is CAplus.

Water-soluble organic nitrogen (WSON) in fine particulate matter (PM_2.5) was determined at urban coastal environments in China based on 1-yr measurement. The WSON concentrations were in a range of 14.3-257.6 nmol N m^-3 and accounted for 22.0-61.2% of the water-soluble nitrogen (WSN) in composition The average total concentration of free amino acid (FAA) was 1264.5 ± 393.0 pmol m^-3, which was lower than those in continental urban cities but nevertheless comparable to the rural area of Pearl River Delta (PRD) in China. The total quantified amines and amino compounds ranged from 223.8 to 806.0 pmol m^-3 in which methylamine, ethylamine, and ethanolamine were the most abundant compounds The average concentration of urea was 7.8 ± 3.0 nmol m^-3 and at least one order of magnitude higher than those in marine and rural areas but comparable to other continental cities in China during non-dust period. Summer showed the highest average concentration of WSON (95.0 ± 66.6 nmol N m^-3) and composition in WSN (49.3%) compared to other seasons (27.9-37.0%). The results were consistent with previous findings that the inorganics can contribute more than the organics in secondary aerosol formation. There were no distinctive seasonal variations of organic compositions of FAA, amine and amino compounds, and urea. This observation was possibly attributed to a mix of original sources in urban and different prevailing wind directions. Fair correlations (r < 0.4) between WSON compounds and atm. oxidants [ozone (O₃) and nitrogen oxides (NO_x)] suggest that biogenic oxidation is possibly not a major contributing factor in atm. coastal urban location.

Zhang, Qiao published the artcileSynthesis and photoluminescence of organotin-dithiothreitol clusters, Recommanded Product: 2-Aminobutan-1-ol, the publication is Journal of Solid State Chemistry (2021), 122056, database is CAplus.

Three novel organotin oxysulfide hybrid clusters (BuSn)₄(DTT)₄M (M = Sn⁴⁺ (1), Ti⁴⁺ (2), Hf⁴⁺ (3); DTT = 1,4-dithiothreitol) were prepared by hydrothermal methods and their crystal structures were determined by single-crystal X-ray diffraction. These clusters are isostructural, pentanuclear complexes containing four peripheral butyltin fragments, and a central metal site of either tin, titanium or hafnium. Solid state variable temperature fluorescence spectra showed that the position and the intensity of key emission peaks of the three isomorphic compounds are significantly different. Compound 1 gave bimodal emission at 420 and 445 nm upon excitation at 360 nm, and its peak positions remained unchanged. Compounds 2 and 3 were excited by 365 and 460 nm radiation, resp., and their maximum emission peaks were red-shifted in different degrees with decreasing temperature All their peak intensity increased with decreasing temperature Solid-state UV/visible diffuse reflectance spectra displayed that these three isostructural compounds have wide optical band gaps of 3.72, 2.68, and 3.19 eV, resp.

Bilgic, Gulbahar published the artcileSynthesis, structural, and electrochemical properties of boron-based ionic liquid, SDS of cas: 96-20-8, the publication is Ionics (2022), 28(7), 3289-3300, database is CAplus.

In the present work, a new boron-based room-temperature ionic liquid (BBRTIL) is reported. An ionic liquid based on the boron cation was synthesized by an easy metathesis procedure yielding clean products. The composition, thermal behavior, phys., and electrochem. properties of the BBRTIL were identified by NMR spectra (NMR), Fourier transform IR (FTIR) thermogravimetric anal. (TGA), linear sweep voltammetry (LSV), and cyclic voltammetry (CV), resp. NMR and FTIR have confirmed the structure formation of 0.3-0.4-mm-sized B₂O₃-based BBRTIL. Furthermore, the correlation between the electrochem. stability and the identified electrolyte equilibrium species was investigated via voltammetry. This procedure, in the future, could be an original alternative to the deposition of elemental boron through easy, one-step synthesis from high-temperature molten salt electrolysis.

Verevkin, Sergey P. published the artcileSustainable hydrogen storage: Thermochemistry of amino-alcohols as seminal liquid organic hydrogen carriers, COA of Formula: C4H11NO, the publication is Journal of Chemical Thermodynamics (2021), 106591, database is CAplus.

Amino-alcs. are considered for sustainable hydrogen storage systems based on catalytic peptide formation. Exptl. and theor. thermochem. studies of amino-alcs. have been performed, including vapor pressure measurements, combustion calorimetry, and quantum-chem. calculations The standard molar enthalpies of vaporization of amino-alcs. were calculated from the temperature dependence of the vapor pressures measured by the transpiration method. Energies of combustion for six amino-alcs. were measured using the high-precision combustion calorimetry. The available in the literature primary data on vapor pressures, enthalpies of vaporization, and enthalpies of formation of amino-alcs. were collected and evaluated. The exptl. standard molar gas-phase enthalpies of formation of amino-alcs. were derived from the evaluated results. The high-level G3B3, G3MP2, and G4 quantum-chem. methods were used to establish consistency of the exptl. and theor. results. The surprisingly low enthalpy of reaction of the reversible dehydrogenation of 2-amino-ethanol, calculated from the exptl. data, makes this liquid organic hydrogen carrier system (LOHC) promising for further optimization and development.
