Bimetallic ruthenium-gold-on-magnesia catalysts: Chemicophysical properties and catalytic activity
(Elsevier, 1980-08)
Bimetallic Ru-Au catalysts supported on MgO were prepared, their atomic composition varying from 100% Ru to 100% Au. Samples were characterized after impregnation and drying at 110 [deg]C and after further reduction by ...
Cyclopropane hydrogenation on Ru and Ru---Au catalysts
(Elsevier, 1980-01)
The rate of reaction between cyclopropane and hydrogen was measured in a flow system on unsupported Ru, Ru/SiO2, andRu/MgO. The effect of the addition of Au to Ru/MgO was also investigated. The temperature was in the range ...
Isotopic oxygen exchange on supported Ru and Au catalysts
(Elsevier, 1980-06)
The isotopic exchange reaction of molecular oxygen is applied to supported ruthenium and gold catalysts. The results on supported ruthenium are similar to those on RuO2. The exchange reaction seems to be unaffected by ...
Thermodynamics of some lanthanide trihalides III. Reinterpretation of LnCl3 Schottky anomalies
(Elsevier, 1980-08)
The heat capacities of the anhydrous lanthanide trichlorides from 5 to 350 K of Sommers and Westrum provide an excellent opportunity further to test the volumetric lattice heat-capacity approximation method. Schottky ...
Structure of the reaction product of pentaphenylgermole and diiron enneacarbonyl: [mu]-(1-(1,2,3,4-tetraphenylbutadienyl)phenylgermylene)octacarbonyldiiron(Fe---Fe)
(Elsevier, 1980-06-17)
Pentaphenylgermole (1-germa-1,2,3,4,5,-pentaphenylcyclopenta-2,4-diene) reacts with diiron enneacarbonyl in refluxing diethyl ether to produce an orange, crystalline complex. This complex was established by single crystal ...
On the dehydration of trans-1,2-dihydrophthalic acid
(Elsevier, 1980)
The epimerization/dehydration of the title compound occurs by way of an enolization rather than a pair of concerted, suprafacial [1,5] hydrogen shifts.
The stereochemistry of ethylene-1,2-d2 epoxidation over silver catalysts
(Elsevier, 1980-10)
The stereochemistry of the catalytic epoxidation of cis-ethylene-1,2-d2 to ethylene oxide over four unsupported and two supported silver catalysts as well as over Ag2O and AgO was studied. Variations of the stereochemistry ...
Structure of the dextran of Leuconostoc mesenteroides B-1355
(Elsevier, 1980-09-15)
The structure of dextran B-1355-S (soluble fraction) has been investigated. Acid hydrolysis of the methylated dextran yielded 2,3,4,6-tetra-, 2,3,4-tri-, 2,4,6-tri-, and 2,4-di-O-methyl--glucose, in the molar ratios of ...
