Abstract A series of experiments was conducted to obtain a nanocomposite based on organo-bentonite and a synthetic polymer polyvinylpyrrolidone by a hydrothermal method. Octadecilaminacetate- processed bentonite was used as organoclay. Obtained samples were investigated by X-ray, IR spectroscopic methods of analysis. It found that samples can also be used as adsorbents.
Abstract The management of the rheological properties of the cement systems and the kinetics of solidification by the use of specially designed complex modifiers has been proved. Modification of cement systems was made possible by the use of a complex modifier (CM) obtained as a result of the interaction of the hyperplasticizer GLENIUM 313 with […]
Abstract Considering structural features of the already known tetradymite-like layered chalcogenide phases, we have attempt to synthesize a new mix-layered compound, SnBi4Te4. The newly synthesized alloy examined by means of differential thermal analysis, powder X-ray diffraction and scanning electron microscope techniques.The melting nature of the discovered phase is found to be incongruently at 831 K. […]
Abstract Influence of rare-earth elements (La, Ho, Yb, Pr) on acidic,textural and catalytic properties of ZSM-5 high-silica zeolite in the reaction of toluene alkylation with isopropanol was studied in the temperature range of 250-350 ° C in a flow unit of ideal displacement. It revealed that the nature of rare earth metal in zeolites ZSM-5 […]
Abstract In the process of gas-phase coherently synchronized oxidation of cyclohexane by hydrogen peroxide in the presence of a heterogeneous biomimetic catalyst per- FTPhPFe3+OH/Al2O3, the reaction products were cyclohexanol, cyclohexanone and cyclohexene. An experimental study aimed at clarifying the routes of cyclohexane conversion into cyclohexanone and cyclohexene made it possible to determine mechanisms for producing […]
