Nanoclay Reinforcement of Liquid Silicone Rubber

Autor: Mark W. Simon, Duan Li Ou, Keith Thomas Stafford

Publikováno v: Journal of Inorganic and Organometallic Polymers and Materials. 18:364-373

Siloxane modified montmorillonite clay was prepared from sodium montmorillonite and quaternary ammonium-containing siloxane surfactant. X-ray diffraction and Fourier transform infrared analyses indicated that the polysiloxane oligomer chains were suc

Publikováno v: Research on Chemical Intermediates. 26:529-548

Pure hydrocarbon plasmas have been generated at low pressures with good efficiency using methane as a reactant. Hydrocarbon plasma discharges containing high energy, free radical, and ionized intermediates were analyzed in situ using emission spectro

Characterization and Catalytic Studies on Defect Sites Formed upon the Thermal Decomposition of Sodium Ionic Clusters in NaX Zeolite

Autor: Steven L. Suib, John C. Edwards, Mark W. Simon

Publikováno v: The Journal of Physical Chemistry. 99:4698-4709

Sodium ionic clusters have been prepared by chemical vapor deposition of sodium metal at 225{degree}C and 1 x 10{sup -4} Torr in NaX zeolites. A maximum loading of approximately 1.2 wt % sodium was vaporized onto dehydrated NaX zeolite. Ionic cluster

Cyclopropane Reactions over Brønsted, Cation, and Metal Sites in Ni/NaX Zeolites

Autor: Steven L. Suib, Mark W. Simon, Carroll O. Bennett

Publikováno v: Journal of Catalysis. 148:100-112

The reactions of cyclopropane in helium and hydrogen were investigated over two different loadings (10.7 and 6.0 wt%) of ion-exchanged Ni/NaX zeolites. The effects of reduction temperatures and hydrogen treatment times on catalytic activity and acidi

Synthesis and Characterization of ZSM-22 Zeolites and Their Catalytic Behavior in 1-Butene Isomerization Reactions

Autor: Chin Lin O'young, Mark W. Simon, Steven L. Suib

Publikováno v: Journal of Catalysis. 147:484-493

ZSM-22 zeolites, having a Si/Al ratio of 45, have been synthesized by sol-gel methods using 1,6-diaminohexane as a templating agent. The structures of these materials have been characterized by X-ray diffraction, transmission electron microscopy and

Isomerization reactions of n-butenes over isomorphously substituted B/A1-ZSM-11 zeolites

Autor: Wen-Qing Xu, Steven L. Suib, Chi-Lin O'Young, Mark W. Simon

Publikováno v: Microporous Materials. 2:477-486

Low levels of boron have been isomorphously substituted into pentasil zeolites and are active in butene isomerization reactions. The acidity of B/A1-ZSM-11 zeolites, measured by NH3 adsorption, is significantly lower than the acidity of B3+-free Al/Z

Publikováno v: Journal of Catalysis. 145:551-560

Boroaluminosilicate zeolites have been used as n-butene isomerization catalysts in this study. Al[sup 3+] free boron zeolites are inactive for n-butene isomerization. Spectroscopic and microscopic studies have been used to monitor the structure, ther

ChemInform Abstract: Cyclopropane Isomerization Over Eu3+NaX Zeolites

Autor: Steven L. Suib, Carroll O. Bennett, Angelos M. Efstathiou, Mark W. Simon

Publikováno v: ChemInform. 24

Cyclopropane isomerization to propylene over various Eu3+ loadings in NaX zeolite have been studied by measurements of steady-state and transient kinetics and by Fourier transform infrared spectroscopy. As Eu3+ loading increases, the rate of deactiva
