This study aimed at producing the biodegradable composite from lignocellulose nanofibers (LCNFs) and Pebax (R) thermoplastic elastomer. For this purpose, LCNFs at different levels of 0, 1, 3, and 5% were considered. The LCNFs were prepared by benzyl alcohol and then mixed with Pebax (R). The liquid phase of the LCNFs and soluble polymer was prepared and then the masterbatches were mixed in an internal mixer (Model 815802, Brabender, Germany). The mixtures from the internal mixer were put into a hot press and test samples were compress-molded. The physical properties results indicated that water absorption and thickness swelling decreased by the addition of more amount of LCNF. By the addition of LCNFs to polymer, the tensile strength and modulus and impact strength were increased compared to samples without LCNF. No regular trend of enthalpy changes was observed as the content of LCNF changed. When the LCNF concentration was increased to 5%, the crystallization temperature was increased. As the LCNF concentration increased to 3%, the glass transition temperature (T-g) was decreased, whereas by incorporating more LCNFs, the T-g was increased. The result of the Fourier transform infrared spectra showed the peaks at 1740 cm(-1) which indicated the presence of polyamide bonds. Also, new peaks were observed in the range of 1400-1500 cm(-1) that was probably related to the presence of C-C bonds of glucose at LCNFs chains.

Nucleophilic addition to the oxy-allyl cation intermediate has emerged as a promising methodology for functionalization of the alpha-position of carbonyl compounds in an umpolung fashion. However, a structure of available carbon nucleophiles to trap the catalytically generated oxy-allyl cation has been limited to highly nucleophilic ones. Herein, we report the Bronsted acid-catalyzed alpha-arylation of ketones employing less explored phenolic nucleophiles as carbon nucleophiles in the oxy-allyl cation catalysis, affording ketones bearing an all carbon quaternary center at the alpha-position.

Given the necessity of sacrificial reductants in various biomimetic aerobic oxygenations, alloxan-catalyzed aerobic redox system for one-pot atom-economic synthesis of sulfinyl-functionalized benzimidazoles was developed by ingeniously binding both the substrate sulfide and sacrificial reductant. This mild and transition-metal-free protocol undergoes two oxidations without additional sacrificial reagents, except for the environmentally benign molecular oxygen. (C) 2020 Elsevier Ltd.

This communication describes the palladium-catalyzed reductive carbonylation of aryl fluorosulfonates (ArOSO2F) using syngas as an inexpensive and sustainable source of carbon monoxide and hydrogen. The conversion of phenols to aryl fluorosulfonates can be conveniently achieved by employing the inexpensive commodity chemical sulfuryl fluoride (SO2F2) and base. The developed continuous flow formylation protocol requires relatively low loadings for palladium acetate (1.25 mol%) and ligand (2.5 mol%). Good to excellent yields of aryl aldehydes were obtained within 45 min for substrates containing electron withdrawing substituents, and 2 h for substrates containing electron donating substituents. The optimal reaction conditions were identified as 120 degrees C temperature and 20 bar pressure in dimethyl sulfoxide (DMSO) as solvent. DMSO was crucial in suppressing Pd black formation and enhancing reaction rate and selectivity.

L-Proline organocatalyst was investigated as an efficient and environmentally benign catalyst for synthesis of some novel bioactive benzil bis(2-cyano-3-aryl-2-propenoylhydrazone) derivatives from reaction of the benzil bis(cyanoacetylhydrazone) with the respective aldehydes. The reusability of the L-proline was tested and the results revealed that the recovered catalyst can be reused at least three additional times in subsequent reactions without significant decrease in product yield. The current protocol is very efficient as it provides mild reaction, cleaner reaction profiles, effortless work phase with outstanding purity, and with short reaction time, high performance of the desired products. IR, H-1-NMR and MS and alternative methods, whenever available, have verified the chemical structures of the newly prepared compounds. Compared to the Doxorubicin reference drug using the MTT assay, the in vitro growth inhibitory activity of ten new compounds was investigated against the liver carcinoma cell line (HepG-2) and the findings revealed promising activities of six derivatives.

Computed Properties of C7H8O2. Auersvald, M; Stas, M; Simacek, P in [Auersvald, Milos; Stas, Martin; Simacek, Pavel] Univ Chem & Technol, Dept Petr Technol & Alternat Fuels, Tech 5, Prague 16628 6, Czech Republic published Electrometric bromine number as a suitable method for the quantitative determination of phenols and olefins in hydrotreated pyrolysis bio-oils in 2021, Cited 29. The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels. However, no routine method currently exists for the reliable determination of these groups in hydrotreated bio-oils (HBOs). In this paper, we analyzed 140 different pure oxygenates as model compounds using the bromine number method (ASTM D1159) observing that most compounds present in HBOs react with one equivalent of bromine. The determination of phenols using bromine number method in crude biooil is complicated especially by the presence of guaiacols and syringols that react with more than one equivalent of bromine and, thus, the obtained result is significantly overestimated. Further we optimized the chromatographic separation of hydrocarbons from HBOs for the selective determination of olefins content. As no other reactive compounds under the conditions of the method, besides phenols and olefins, were observed in HBOs, the difference between HBO bromine number (before hydrocarbons separation) and olefins content correspond to the total amount of phenols. The method was finally applied to 11 HBOs with different content of oxygen, providing a good correlation between phenols and oxygen content.

Since bisphenol A (BPA) exhibits endocrine disrupting action and high toxicity in aqueous system, there are high demands to remove it completely. In this study, the BPA removal by sonophotocatalysis coupled with nano-structured graphitic carbon nitride (g-C3N4, GCN) was conducted with various batch tests using energy-based advanced oxidation process (AOP) based on ultrasound (US) and visible light (Vis-L). Results of batch tests indicated that GCN-based sonophotocatalysis (Vis-L/US) had higher rate constants than other AOPs and especially two times higher degradation rate than TiO2-based Vis-L/US. This result infers that GCN is effective in the catalytic activity in Vis-L/US since its surface can be activated by Vis-L to transport electrons from valence band (VB) for utilizing holes (h(VB)(+)) in the removal of BPA. In addition, US irradiation exfoliated the GCN effectively. The formation of BPA intermediates was investigated in detail by using high-performance liquid chromatography-mass spectrometry (HPLC/MS). The possible degradation pathway of BPA was proposed.

The first total synthesis of the cytotoxic alkaloid ritterazine B is reported. The synthesis features a unified approach to both steroid subunits, employing a titanium-mediated propargylation reaction to achieve divergence from a common precursor. Other key steps include gold-catalyzed cycloisomerizations that install both spiroketals and late stage C-H oxidation to incorporate the C7′ alcohol.

A selective, economical, and ecological protocol has been described for the oxidation of methyl arenes and their analogs to the corresponding carbonyl compounds and epoxidation reactions of alkenes with molecular oxygen (O-2) or air as a green oxygen source, under mild reaction conditions. The nano Ni/g-C3N4 exhibited high photocatalytic activity, stability, and selectivity in the C-H activation of methyl arenes, methylene arenes, and epoxidation of various alkenes under visible- light irradiation without the use of an oxidizing agent and under base free conditions.
