Novel dehydration of stilbene oxides to diphenylacetylene using flash vacuum thermolysis with solid acid catalysts

Autor: Frederik R. van Buren, Binne Zwanenburg, Adri C.L.M. van der Waals, Antonius J. H. Klunder

Publikováno v: Journal of Molecular Catalysis A: Chemical. 134:179-189

Isomerization of cis- and trans-stilbene oxide was achieved under catalytic flash vacuum thermolysis (FVT), using silica–alumina and clay as catalysts. Depending on the amount of catalyst and reaction temperature, rearrangement to diphenylacetaldeh

Iron oxide dehydrogenation catalysts supported on magnesium oxide. Part 1.—Preparation and characterization

Autor: Johan J. Schokker, Adriana W. Stobbe-Kreemers, Dick E. Stobbe, Frederik R. van Buren, John W. Geus, Adrianus J. van Dillen

Publikováno v: J. Chem. Soc., Faraday Trans.. 87:1623-1629

Iron oxide catalysts supported on magnesium oxide have been prepared by impregnation of a preshaped magnesium oxide support to incipient wetness with poorly crystallizing organometallic complexes. As organometallic complexes ammonium iron(III) citrat

Publikováno v: J. Chem. Soc., Faraday Trans.. 87:1639-1647

The catalytic behaviour of iron oxide catalysts supported on magnesium oxide in the non-oxidative dehydrogenation of but-1-ene to buta-1,3-diene has been studied. Under dehydrogenation conditions the magnesium ferrite phase of the fresh catalyst was

Iron oxide dehydrogenation catalysts supported on magnesium oxide. Part 2.—Reduction behaviour

Autor: Dick E. Stobbe, John W. Geus, Adriana W. Stobbe-Kreemers, Frederik R. van Buren, Adrianus J. van Dillen

Publikováno v: J. Chem. Soc., Faraday Trans.. 87:1631-1637

The reduction behaviour of iron oxide supported on magnesium oxide has been studied using temperature-programmed reduction (TPR), X-ray diffraction (XRD), and high-field magnetic measurements. The catalysts, containing 1–6 wt.% Fe, were prepared by

Publikováno v: Vrije Universiteit Brussel

Zeolite X successively exchanged with Ca 2+ and Co 2+ ions is an efficient absorbent for traces removal of cyclopentadiene from alkene mixtures. To understand this affinity and stability of the aluminosilicate with this combination of cations, detail

Selective ethylene trimerization: A study into the mechanism and the reduction of PE formation

Publikováno v: Journal of Molecular Catalysis A-Chemical, 248(1-2), 237-247

In the present study, the titanium-catalyzed ethylene trimerization in general, and more specifically, the concomitant PE formation have been studied. The polymer formation is undesirable as it not only will lead to lower I-hexene yields, but it can

Publikováno v: Journal of Materials Chemistry. 1:539

Two commercial preshaped magnesium oxides, viz. pellet-shaped magnesium oxide (Englhard, Mg-0601) and spherical magnesium oxide (Sud-Chemie, T-4403), have been evaluated for use as carrier material in supported dehydrogenation catalysts. The influenc
