    Notes: Abstract The reaction of alkyl- and benzylglycidylmalonic esters with pyrrolidinone, piperidinone, and caprolactam in the presence of catalytic amounts of water leads to compounds containing lactone and lactam rings and also to 2-alkyl- and 2-benzyl-5-hydroxy-γ-valerolactones.

    Description / Table of Contents: Abstract Измерены спектры диффузного отражения катализаторов диспропорционирования пропилена WO3/SiO2 и WO3/γ-Al2O3 для различных стадий обработки зтих образцов, в частности, для случая обработки WO3/SiO2 парами HCl. Покзано, что в случае WO3/γ-Al2O3 температуры начала реакции и восстановления окиси вольфрама совпадают.
    Notes: Abstract Diffuse reflectance spectra have been recorded for WO3/SiO2 and WO3/γ-Al2O3 catalysts after various steps of treatment of these samples, in particular, after treatment of WO3/SiO2 by HCl. It is shown that for WO3/γ-Al2O3 the temperatures of the onset of reaction and WO3 reduction coincide.

    Diffuse reflectance spectroscopic studies of supported molybdenum oxide catalysts for propene metathesis (1978)

    Description / Table of Contents: Abstract Измерены спектры диффузного отражения окиси молибдена, нанесенной на γ-Al2O3 и SiO2 в количестве 10% вес. для различных стадий обработки этих систем. γ-Al2O3 была предварительно обработана 0,05% и 1,0% KOH. Сравнение полученных в настоящей работе спектральных данных и каталитических свойств этих систем позволяет сделать заключение об оптимальном окислительном состоянии ионов молибдена в поверхностных кластерах (∼ Mo5+), необходимом для получения нанесённых окисномолибденовых катализаторов диспропорционирования пропилена с высокой каталитической активностью и селективностью.
    Notes: Abstract Diffuse reflectance spectra of 10 wt.% MoO3 supported on γ-Al2O3 and SiO2 have been measured after various steps of treatment. γ-Al2O3 was pretreated by 0.05 and 1.0 wt.% KOH. The comparison of spectral data and catalytic properties allows to predict the optimal oxidation state of molybdenum ions in surface clusters (approximately Mo5+), necessary to obtain supported MoO3 catalysts for propene metathesis with high activity and selectivity.

    Description / Table of Contents: Abstract Изучено влияние окисления пропана в режиме стабилизированного холодното пламени на хлоричы щелочных металлов. Показано, что в этих условиях с поверхности частично удаляется хлор и образуются щелочь и формиат. Образование формиата однозначно зарегистрировано с помошью ИК спектроскопии. Обнаружено также, что на такой поверхности в зоне холодного пламени возникает избыточный разогрев по сравнениы с необработанной поверхностыо. Этот разогрев, достигаыший 23°C, может быть обусловлен рекомбинацией радикалов на поверхности.
    Notes: Abstract Studies of the effect of stabilized cool flame propane oxidation on alkali metal chlorides have revealed the partial removal of surface chlorine and the formation of alkali and formiate. Formiate formation was tentatively detected by IR spectroscopy. Excess heating (up to 23°C) established on such surfaces in the zone of cool flame compared to untreated ones, can be due to the recombination of surface radicals.

    The nature of the active centers of propylene-disproportionation catalysts (1977)

    Notes: Conclustions 1. Preliminary treatment of alumina with KOH increases the catalytic activity of an MoO3-Al2O3 catalyst. The curve of the specimen activity vs alkali content passes through a maximum. 2. Treatment with HCl vapor activates a WO3-SiO3 catalyst, and decativates an MoO3-Al2O3 catalyst, in propylene disproportionation. 3. According to the IR spectra, when propylene is adsorbed on a catalyst obtained by deposition of Mo(CO)6 onto Al2O3, it is coordinated by the molybdenum atom.
