The situation evolved in the domain of fuel additives production during 2011-2015 is reviewed through the analysis of literature and patent sources and statistical data. The main trends in development of additives are determined and the main types of additives are characterized. It is noted that the interest of developers worldwide was focused on additives of biocomponents (oxygenates and biodiesel). In Russia, where imported additives were prevalent until recently, active process of import substitution has begun. The additive demand of Russian refineries for the production of modern quality fuels is analyzed and the domestic developments are characterized. Technical solutions that offer alternatives to the use of additives are proposed.

Calorimetry provides an accurate and reliable method to determine the enthalpies of formation of organic molecules in the gas phase. From the experimental formation enthalpies and the absolute entropies, obtained by theoretical calculations, it is possible to perform Gibbs energy calculations. This thermodynamic function is widely used to describe various thermodynamic processes, such as chemical equilibrium, and allows the calculation of equilibrium constants. The specific standard combustion energies of 3,5-dimethylisoxazole-4-carboxylic acid, 5-methylisoxazole-3-carboxylic acid, 5-amino-3-methylisoxazole, and 3-amino-5-methylisoxazole were determined by using a combustion calorimeter. The sublimation enthalpies of the compounds were determined by means of the Knudsen effusion technique. From these values, the molar standard enthalpy of formation in gaseous phase of each compound was calculated. Theoretical calculations at the G3 and G4 levels were performed, and a study of the molecular and electronic structure of these compounds was carried out. The calculated enthalpies of formation are in very good agreement with the experimental values. From both the experimental and theoretical results, five gas phase chemical equilibria were studied: one of isomerization, two of CO2 loss, and two of NH3 loss. The equilibrium constants for each process were calculated, which allow prediction of the direction of the chemical process from a thermodynamic viewpoint.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Recommanded Product: 1072-67-9. Introducing a new discovery about 1072-67-9, Name is 5-Methylisoxazol-3-amine

Hierarchical three-dimensional (3D) porous architecture FeIIFeIII layered double hydroxide (LDH) multiwall was grown on carbon-felt (CF) substrate via solvothermal process. The as-deposited FeIIFeIII LDH/CF cathode was composed of highly oriented and well crystallized interconnected nanowalls with high electrical conductivity and excellent catalytic activity over a wide pH range (pH 3?9) for heterogeneous electro-Fenton (HEF) degradation of antibiotic sulfamethoxazole (SMT) in aqueous medium. Mineralization efficiencies (in terms of TOC removal) of ?97%, 93% and 90% was achieved at pH 3, 6 and 9 respectively for FeIIFeIII cathode during HEF treatment of 0.2 mM SMT solution at applied current density of 7.5 mA cm?2 using Ti4O7 anode. Comparative electro-Fenton (EF-Fe2+) with 0.2 mM Fe2+ or electrooxidation with H2O2 production (EO-H2O2) studies using raw CF cathode at similar experimental conditions showed relatively lower mineralization with highest TOC removal efficiency of 77% and 64% obtained at pH 3 for EF-Fe2+ and EO-H2O2 respectively. Oxidative degradation of SMT in HEF system was by (i) Ti4O7([rad]OH) generated at anode surface at all pH studied, (ii) surface catalyzed process and (iii) contribution from homogeneous catalyzed process at pH 3 due to leached iron ions. The prepared FeIIFeIII LDH/CF exhibited excellent catalytic stability with good reusability up to 10 cycles of 4 h treatment at pH 6. Initial SMT solution showed relatively high toxicity but total detoxification of the solution was attained after 8 h of treatment by HEF with FeIIFeIIILDH/CF cathode. HEF with FeIIFeIII LDH/CF cathode is an exciting technique for remediation of organic contaminated wastewater.

Diarylmethylamido bis(phenols) have been subjected to peptide-catalyzed, enantioselective bromination reactions. Desymmetrization of compounds in this class has been achieved such that enantioenriched products may be isolated with up to 97:3 er. Mechanistically, the observed enantioselectivity was shown to be primarily a function of differential functionalization of enantiotopic arenes, although additional studies unveiled a contribution from secondary kinetic resolution of the product (to afford the symmetrical dibromide) under the reaction conditions. Variants of the tetrapeptide catalyst were also evaluated and revealed a striking observation – enantiodivergent catalysis is observed upon changing the achiral amino acid residue in the catalyst (at the i+2 position) from an aminocyclopropane carboxamide residue (97:3 er) to an aminoisobutyramide residue (33:67 er) under a common set of conditions. An expanded set of catalysts was also evaluated, enabling structure/selectivity correlations to be considered in a mechanistic light.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

High-precision 14N NMR shieldings are reported for all five available oxazoles and oxadiazoles in a variety of solvents. Both solvent polarity and hydrogen-bond effects on the nitrogen nuclear shieldings of the solutes are significant and comparable in magnitude; both give rise to shielding increases. The increasing solvent polarity favors delocalization of electrons from oxygen atoms into the heteroaromatic rings with a concomitant electron charge accumulation on the nitrogen atoms concerned. This trend is parallel to those found for analogous diazole and triazole heteroaromatic systems. Solvent-to-solute hydrogen bonding causes an increase in nitrogen shielding when the nitrogen atoms in question are involved in the hydrogen bonding as acceptor sites. This reflects not only local effects of hydrogen bonding to a particular nitrogen atom but also those arising from competition between other acceptor sites in a given molecule; these include oxygen and other nitrogen atoms. TNDO/2-calculated nitrogen shieldings, with respect to neat nitromethane, give a very good linear correlation with experimental results when all of the nitrogen atoms in the molecules studied are taken into account. The present study of nitrogen shieldings provides a valuable insight into solvent polarity effects on electric charge distribution in nitrogenous heteroaromatic systems, as well as into possible competition between various hydrogen-bond acceptor centers with respect to hydrogen-bond donor Solvents.

Liquid crystals (LCs) are ordered soft materials formed by self-assembling molecules, which combine anisotropic properties with the fluidity of a liquid. They can potentially be used as functional materials for electron, ion or molecular transport, which can be applied in opto-electronic devices, aligned electrolytes and biological systems. In particular, the calamitic LCs have been promising candidates from the very beginning of liquid crystal research, are applied successfully in various optical devices and are recently rediscovered in the field of organic semiconductors. New LCs with low viscosity, adapted mesophase range and structure, and high reliability were necessary to achieve the rapid transformation from flat computer monitors to large displays for television. This review highlights remarkable mesophase stability and physical properties, and potential applications of various heterocyclic calamitic LCs in modern devices.

The GIAO (Gauge Including Atomic Orbitals) DFT (Density Functional Theory) method is applied at the B3LYP/6-31+G(d,p)//B3LYP/6-31+G(d), B3LYP/6-311++G(d,p)//B3LYP/6-31+G(d), B3LYP/6-311+G (2d,p)//B3LYP/6-31+G(d) and B3LYP/6-311++G(d,p)//B3LYP/6-311++G(d,p) levels of theory for the calculation of proton and carbon chemicals shifts and coupling constants for 25 nitro-substituted five-membered heterocycles. Difference (1D NOE) spectra in combination with long-range gHMBC experiments were used as tools for the structural elucidation of nitro-substituted five-membered heterocycles. The assigned NMR data (chemical shifts and coupling constants) for all compounds were found to be in good agreement with theoretical calculations using the GIAO DFT method. The magnitudes of one-bond (1JCH) and long-range (nJCH, n > 1) coupling constants were utilized for unambiguous differentiation between regioisomers of nitro-substituted five-membered heterocycles.

Psoriasis is a chronic T-cell-mediated autoimmune disease, and FMS-like tyrosine kinase 3 (FLT3) has been considered as a potential molecular target for the treatment of psoriasis. In this investigation, structural optimization was performed on a lead compound, 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)phenyl)-3-(4-chloro-3-(trifluoromethyl)phenyl)urea (1), which showed a moderate inhibitory activity againt FLT3. A series of pyrazolo[3,4-d]pyrimidine derivatives were synthesized, and structure-activity relationship analysis led to the discovery of a number of potent FLT3 inhibitors. One of the most active compounds, 1-(4-(1H-pyrazolo[3,4-d]pyrimidin-4-yloxy)-3-fluorophenyl)-3-(5-tert-butylisoxazol-3-yl)urea (18b), was then chosen for in-depth antipsoriasis studies because this compound displayed the highest potency in a preliminary antipsoriasis test. Compound 18b exhibited significant antipsoriatic effects in the K14-VEGF transgenic mouse model of psoriasis, and no recurrence was found 15 days later after the last administration. Detailed mechanisms of action of compound 18b were also investigated. Collectively, compound 18b could be a potential drug candidate for psoriasis treatment.
