Simulations of Interlayer Methanol in Ca- and Na-Saturated Montmorillonites Using Molecular Dynamics
Methanol Molecular Dynamics Montmorillonite
2011/12/5
Abstract: Molecular dynamics computer simulations were used to study methanol molecules confined between the layers of 2:1 phyllosilicates. The model systems are based on natural Ca- and Na-rich montm...
Naturally-Occurring Silicates as Carriers for Copper Catalysts Used in Methanol Conversion
Bentonite Copper catalysts Methanol dehydrogenation Sepiolite
2011/12/30
Bentonite- and sepiolite-supported copper catalysts have been prepared either by adsorption of Cu(II) from aqueous solutions of copper nitrate at pH …4.5 or by adsorption ofa [Cu(NH3)4]2+ complex from...
Vapor-Phase Sorption Kinetics for Methanol, Propan-2-OL, and 2-Methylpropan-2-OL on Al3+-, Cr3+-, and Fe3+-Exchanged Montmorillonite
Adsorption Alcohol Diffusion Grain size Mass transfer Montmorillonite
2012/1/11
The rate of sorption of methanol (MeOH), propan-2-ol (i-PrOH), and 2-methyl-propan-2-ol (t-BuOH) onto a Wyoming montmorillonite saturated with Al3+-, Cr3+-, or Fe3+-cations has been studied by isother...
Reactions of the Conjugated Dienes Butadiene and Isoprene Alone and with Methanol over Ion-Exchanged Montmorillonites
Butadiene Catalysis Diels-Alder reaction Gas-liquid chromatography Isoprene Methanol Montmorillonite Transition metal
2012/1/12
The reactions of simple conjugated dienes over divalent and trivalent transition metal-exchanged montmorillonites yield, in the absence of nucleophiles, a variety of products. Some of these products a...
Synthesis of Methyl-t-Butyl Ether from Methanol and Isobutene Using a Clay Catalyst
Catalysis Methyl-t-butyl ether Smectite
2012/2/7
The acid-catalyzed reaction between methanol and isobutene to give methyl-t-butyl ether may be carried out using a cation-exchanged smectite as the catalyst. In 1,4-dioxan solvent at 60∑C smectites ex...
