    Olefins polymerization on titania and titania-supported rhodium (1991)
    Springer
    Catalysis letters 8 (1991), S. 37-43 
    Details
    ISSN: 1572-879X
    Keywords: Olefins polymerization ; Rh/TiO2 catalysts ; titania ; rhodium
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The adsorption of ethene and propene on titania and titania-supported rhodium has been studied, observing a continuous adsorption even after 24 h. The samples have been reduced at 623 or 773 K, but no difference was observed, whichever the reduction temperature or the presence of rhodium, on the amount of gas adsorbed per unit of surface area of the solid. A study of the polymerization has been done following the “equal reactivity hypothesis”, and it has been concluded that the role played by the rhodium particles is to facilitate adsorption of the gaseous molecule, that is then transfered to the surface of the support, where it polymerizes.

    Excess molar volumes and viscosities of the ternary systemn-butylamine + 1,4-dioxane + acetonitrile at 25°C (1990)
    Springer
    Journal of solution chemistry 19 (1990), S. 1085-1094 
    Details
    ISSN: 1572-8927
    Keywords: Densities ; viscosities ; n-butylamine + 1,4-dioxane + acetonitrile system ; excess molar properties ; ternary system
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Densities and viscosities for the n-butylamine + 1,4-dioxane + acetonitrile system were determined at 25°C and molar excess volumes and excess viscosities were calculated. Of the different expressions existing in the literature that predict these excess properties for ternary mixtures from data for the binary mixtures, the empirical correlation of Singh et al. is the best for this system.

    Description / Table of Contents: Abstract Реакции окислительного соединения метана исследовали на катализаторах Li/MgO, приготовленных из трёх различных предшественников MgO и карбоната или нитрата лития. В образцах, приготовленных из Li2CO3, остатки последнего на поверхности носителя благоприятствуют образованию окислов углерода.
    Notes: Abstract Oxidative coupling of methane has been studied on Li/MgO catalysts prepared from three different MgO precursors and from lithium carbonate or nitrate. In samples prepared from Li2CO3, the persistence of this on the support surface favors formation of carbon oxides.

    Ethene hydrogenation by Rh/TiO2 under SMSI conditions (1993)
    Springer
    Reaction kinetics and catalysis letters 51 (1993), S. 319-324 
    Details
    ISSN: 1588-2837
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Hydrogenation of ethene has been studied at 185–230 K on a Rh/TiO2 catalyst reduced at 473–773 K. The activity decreases on increasing the reduction temperature, even at 500 K, but it is more evident when reduction is carried out at 773 K. Oxidation and reduction recovers the activity in hydrogenation.

    Description / Table of Contents: Abstract Описывают активность катализатора Rh/TiO2 (0,6 вес.% Rh), приготовленного ионным обменом и восстановленного при различных скоростях нагрева, в гидрогенолизе н-бутана. Скорость нагрева не влияет на свойства катализатора: получены одинаковые дисперсности и активности. Углекислые остатки, образующиеся при высоких температурах, удаляют водородом при комнатной температуре, регенерируя, таким образом, активностя.
    Notes: Abstract The activity in n-butane hydrogenolysis of Rh/TiO2 (0.6 wt.% Rh) catalysts prepared by ion exchange and reduced at different heating rates is reported. The heating rate has no major effect on the properties of the catalysts (similar dispersions and activities are achieved). Carbonaceous residues formed at high temperature are removed by hydrogen at room temperature, thus leading to recovery of the activity.
