    Description / Table of Contents: Abstract С помощью метода програмированной термодесорбции установлено, что на катализаторе Ni−Al2O3 индан адсорбируется на активнных центрах двух типов: I−Al2O3 и II−Ni. Активные центры Al2O3 катализатора Ni−Al2O3 отличаются от активных центров Al2O3. В присутствии водорода часть индана адсорбированного активными центрами типа II деструктируется.
    Notes: Abstract By the method of temperature programmed desorption, it has been established that the adsorption of indane on a Ni−Al2O3 catalyst occurs on two types of active sites: (I) Al2O3 and (II) nickel. The active sites of Al2O3 in the Ni−Al2O3 catalyst differ from those on pure Al2O3. In the presence of hydrogen, part of the indane adsorbed on type II active sites undergoes decomposition.

    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.

    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.

    Reaction of oxygen with surface propylene complexes on CoO-MgO solid solutions (1975)

    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.
