Evaluation of the Acidity of Pillared Montmorillonites by Pyridine Adsorption
Acidity Al-Pillared Montmorillonite Mesoporous Materials Pyridine Adsorption Zr-Pillared Montmorillonite
2011/12/6
Abstract: Two series of pillared clays were prepared from a purified montmorillonite (95%) from La Serrata of Nijar, Spain, and polycations of Al and Zr using various methods. The effect of both the p...
Kaolinite-Pyridine Intercalation Compound derived from Hydrated Kaolinite
Hydrated kaolinite Infrared spectroscopy Intercalation Kaolinite Nuclear magnetic resonance Pyridine X-ray powder diffraction
2012/1/5
A kaolinite-pyridine intercalation compound was prepared using hydrated kaolinite as an intermediate. Hydrated kaolinite having a basal spacing of 10 侌 was treated with pyridine to form a well-ordered...
Review of the Diffusion of Water and Pyridine in the Interlayer Space of Montmorillonite: Relevance to Kinetics of Catalytic Reactions in Clays
Catalysis Diffusion Interlayer space Kinetics Montmorillonite Pyridine Water
2012/2/1
With the current interest in the use of transition metal-exchanged phyllosilicates as catalysts for novel organic syntheses, investigations into the factors which affect the movement of reactant, prod...
The Diffusion of Interlamellar Water in the 23.3 A Na-Montmorillonite:Pyridine/H2O Intercalate by Quasielastic Neutron Scattering
Diffusion Intercalate Montmorillonite Neutron Pyridine Quasielastic
2012/2/9
The diffusion of water in the title intercalate has been measured by quasielastic neutron scattering. The diffusion coefficient (6.1 × 10−7 cm2 s−1 at 23.5°C) is one order less than that f...
Adsorption of Pyridine N-Oxide onto Montmorillonite
Adsorption Pyridine N-Oxide Montmorillonite
2012/2/15
Pyridine N-oxide and montmorillonite form interlamellar complexes with basal spacings of 14·7 and 21 ∈. The former corresponds to a monolayer with a tilted orientation of the pyridine ring; the latter...
