  • Synergistic Effects of Conjugation and Polarization on Dual Amide
           Hydrogen-bonding in CCl4: Theory and Experiment

    • Abstract: Publication date:  May 2018
      Source:Universal Journal of Chemistry  Volume  6  Number  2  Shannon G. Lieb   and Paula LeBlanc   The doubly hydrogen-bonded dimer of pyrrolidinone (γ-lactam) is used as a benchmark for the effect of conjugation on the strength and extent of hydrogen-bonding of the compounds Oxindole and Isoxindole. The experimental portion of this project consists of collecting the FTIR spectrum of γ-lactam, Oxindole and Isoxindole in CCl4. The concentrations and temperatures were varied to determine the thermodynamic properties of ΔHd, ΔSd and Kd. In addition, the spectroscopic parameters of the difference of the monomer and dimer N-H stretching frequencies (Δν) and the ratio of the molar extinction coefficients of the dimer and monomer (εd/εm) are experimentally determined. The values of ΔHd, ΔSd, Δν and εd/εm are computed using MP2 and B3LYP methods with 6-31G** and 6-31+G** basis sets. The experimental values are best described by B3LYP/6-31G**with the incorporation of the dielectric effect (PCM) of CCl4. The experimental and computational results support the results of increased or decreased hydrogen-bond strength due to conjugation effects on the polarization of the monomers in forming dimers.

  • Express-method for Estimation of Electrocatalytic Activity of Oxide Films
           toward Oxygen Transfer Reactions

    • Abstract: Publication date:  May 2018
      Source:Universal Journal of Chemistry  Volume  6  Number  2  Veronika Poltavets   Viktor F. Vargalyuk   and Lyudmila Shevchenko   Oxidation catalysis of organic substances has attracted special attention in recent years due to of their high industrial significance in green and energy chemistry. The implementation of a transition metal-based catalyst in combination with oxygen is an alternative to the traditional procedures. This study justifies the application of amperometric response 'in situ' for estimation of the electrocatalytic activity of metal oxide films, which are known to be promising for oxygen transfer processes. The reaction of electrooxidation of Mn2+ ions may be termed as a 'marker' for oxygen transfer reactions due to its kinetic features, such as proportionality between the current density and the surface concentration of •OH-radicals. The relative parameter, kox, has been offered for estimation of the oxidizing capacity of an anode material toward oxygen transfer reaction in reference to platinum oxidizing capacity. kox value is automatically calculated exactly during electroplating of MnOx as a ratio of the current density of Mn2+ + 2H2O – 2e→MnO2+4H+ reaction on the tested surface to the current density of this reaction on Pt surface. The developed method was tested during the investigation of catalytic activity of MnOx films for electrooxidation of glucose. The parameter kox was calculated for other anode materials and was analyzed. The application of the new method allows estimating and comparing the catalytic performance toward oxygen transfer reactions of anode materials or of the same material in different modifications, such as nano particles, composites, different compositions etc. The pre-test reduces manifold the time spent for determination of oxidizing capacity of oxides.
