    Description / Table of Contents: Abstract Проведены термодесорбционные исследования взаимодействия пропилена и кислорода на твердых растворах CoO−MgO. Получены значения энергии активации десорбции, Ed, для 12% CoO−MgO 1,5% CoO−MgO и MgO рав ные 10,5, 6,5 и 8,8 ккал/моль, соответственно. Показано, что предварительнчя адсорбция кислоропа или совместная алсорбция кислорода на исследованных твердых растворах приводит к необратимой адсорбции пропилена.
    Notes: Abstract Thermodesorption studies on the interaction of propylene and oxygen over solid CoO−MgO solutions have been carried out. The activation energy of desorption, Ed, for 12% CoO−MgO, 1, 5% CoO−MgO and MgO samples was found to be 10.5, 6.5 and 8.8 kcal/mol, respectively. Pre-adsorption of oxygen or simultaneous adsorption of propylene and oxygen were shown to lead to irreversible adsorption of propylene on the solid solutions.

    ISSN: 1573-9171

    Notes: Conclusions The kinetic parameters of the reaction of cycloparaffins from C5 to C12 with ozone were obtained experimentally. From a comparison of the preexponential factors Acalc and Aexp, it was concluded that the structure of the transition complex (RH...O3) is linear, which permits us to give preference to the mechanism RH + O3 →〉 R. + HO. + O2.

    Reaction of oxygen with surface propylene complexes on CoO-MgO solid solutions (1975)
    Springer
    Russian chemical bulletin 24 (1975), S. 1542-1544 
    Details
    ISSN: 1573-9171

    Topics: Chemistry and Pharmacology
    Notes: Conclusions 1. The reaction of oxygen with surface-propylene complexes at room temperature on a 0.1% CoO-MgO sample leads to the formation of mild oxidation products with their escape into space. 2. The effect of a discrete, “jumplike” liberation of the reaction product was detected in the case of the 0.1% CoO-MgO sample, with a simultaneous sharp increase in the oxygen absorption. This effect is practically absent for the 12% CoO-MgO. 3. A possible mechanism was proposed for the reaction of oxygen with surface-propylene complexes.

    Description / Table of Contents: Abstract Методом ЭПР показано, что на поверхности 1% CoO−MgO после подачи на образец импульсов кислорода при комнатной температуре образуются ион-радикалы O 2 − с gI=2.0085 и gII=2.087. Нагревание образца в резонаторе спектрометра до 150 °C приводит к полному исчезновению в ЭПР-спектрах сигнала O 2 − . Получена зависимость изменения интенсивности сигнала O 2 − во времени как результат взаимодействия адсовбированных пропилена и кислорода на поверхности образца.
    Notes: Abstract An ESR study has shown that under the action of oxygen pulses, radical ions O 2 − with gI=2.0085 and gII=2.087 are generated at room temperature on the surface of 1% CoO−MgO. Heating of the sample to 150 °C in the spectrometer results in complete disappearance of the O 2 − signal from the ESR spectra. The variation of the O 2 − signal intensity with time due to the interaction between propene and oxygen adsorbed on the sample surface, has been measured.

    Description / Table of Contents: Abstract Исполъеование MoO3 в качестве модифицирующего агента при получении нанесенных палладиевых катализаторов ведет к повышению дисперсности металлического палладия вследствие более равномерного распределения первоначально нанесенной соли (PdCl2). Он повышает адсорбционную способность поверхности металла к реагирующему олефину (стирол) и понижает ее к водороду за счет электроно-акцепторного влияния молибденовых ионов.
    Notes: Abstract Increase in dispersity of supported plladium was found in the presence of MoO3 due to a more even distribution of the precursor (PdCl2). It was observed that the metal-support interaction leads to a considerable increase of styrene adsorption and decrease of hydrogen adsorption under the influence of electron-acceptor molybdena ions.

    Some aspects of electronic interactions in heterogeneous catalysis (1987)

    Topics: Chemistry and Pharmacology
    Notes: Concluding remarks The examples we have discussed indicate that it is possible, on the basis of quantum-chemical description of the interaction between energy levels, to explain many processes in heterogeneous catalysis. The division into electronic and geometrical factors appeared historically, as an analysis of the processes, with the aim to simplify their understanding. The present development of the theory of catalysis shows that achieving of the basic goal, e.g. explanation and prediction of the properties of catalytic systems necessitate a synthesis between the components and the mechanism of their action. Undoubtedly, this synthesis can be carried out successfully only upon recognition of the decisive role of electron factor.
