AbstractThe kinetic characteristics, mechanisms of activity, and relationship between the antioxidant activity and the molecular and supramolecular structure of fullerene C60 and some of its N-monosubstituted amino acid derivatives have been studied. The introduction of an amino acid substituent in the C60 fullerene molecule led to an increase in i...

AbstractThe kinetics of the reaction of phenylnitroso oxide, para-CH3-, para-CH3O-, and para-Br-phenylnitroso oxides with benzoquinones in acetonitrile at room temperature was studied by flash photolysis. Both nitroso oxide isomers were involved in the reaction, the rate constants for the cis forms being higher than for the trans isomers for all co...

AbstractThe kinetics of oxidation of diethyl sulfide (Et2S) with hydrogen peroxide (H2O2) in aqueous solutions of acetonitrile (MeCN) was studied using a kinetic distribution method. It was found that the order of the reaction with respect to the substrate depends on pH and changes from the first at pH 8.06 to nearly zero at pH 11.02. The initial r...

AbstractThe reaction of carbon dioxide with propylene oxide was carried out in the presence of a new pentadentate chromium complex, dichloro[2,6-diacetylpyridine bis(4-tert-butylbenzoylhydrazone)]chromium(III). The reaction kinetics was studied under different reaction conditions (temperature, pressure, and catalyst concentration). Optimal conditio...

AbstractSome of the kinetic parameters of esterifications of aliphatic acids and alcohols involving biocatalysts in nonaqueous media were analyzed using mathematical modeling. The kinetic equations were solved by the modified Runge–Kutta–Merson method, which provided the specified accuracy. The acids of the C3–C8 series were used as donors of acyl ...

AbstractIn this work Si/HZSM-5-0.09M catalyst was prepared using desilication and regrowth of SiO2 method, which was characterized by XRF, XRD, SEM, NH3-TPD, and N2 adsorption/desorption. Meanwhile, the structure–activity relationship was comprehensively discussed. The results revealed that the aromatics total selectivity of Si/HZSM-5-0.09M catalys...

AbstractHerein we report a core–shell structured [email protected] nanorod with precisely located carbon and carbon nitride, fabricated by a nanocasting method using externally functionalized “non-calcinated” SBA-15 as a template. The resultant [email protected] core–shell architecture not only promotes the charge separation and visible light absorption, but also im...

AbstractThe review describes the main chemical processes used in the preparation of glyphosate by different methods. Methods for the synthesis of glyphosate are considered, both industrial syntheses (from glycine and by oxidation of N-(phosphonomethyl)-iminodiacetic acid (PhIDAA)) and promising “atom-efficient” methods (dealkylation of N-substitute...

AbstractCopper-containing catalysts based on CeO2–ZrO2 solid solutions were prepared by the Pecini method and studied using a set of physicochemical methods. It was found that the bond strength of oxygen on the catalyst surface, which depends on the properties of supported copper oxide clusters and a ratio between CeO2 and ZrO2 in the support, play...

AbstractThe results of experimental studies on the hydrolysis of concentrated aqueous solutions of sodium borohydride in a concentration range of 1.05–6.3 mol/kg at temperatures of 20–80°C with the use of Co/TiO2 powder as a model catalyst are presented. Based on the results of the experiments, an approximation of the rate of the process was propos...
