Preparation and Characterization of Two Distinct Ethylene Glycol Derivatives of Kaolinite
Ethylene glycol Interlamellar modification Kaolinite
font style='font-size:12px;'>
2011/12/29
A new, well-ordered, thermally robust ethylene glycol intercalate of kaolinite was formed by refluxing the dimethyl sulfoxide intercalate of kaolinite (Kao-DMSO) with dry ethylene glycol (EG). This ne...
Formation of Polyethylene Glycol on Montmorillonite by Sterilization with Ethylene Oxide
Adsorption Infrared spectroscopy Ethylene oxide Interlayer cations Montmorillonite Polymerization Sterilization X-ray powder diffraction

2012/1/4
The effect of ethylene oxide-sterilization on homoionic (Na+, K+, Ca2+, Cu2+, Al3+, and Fe3+) montmorillonite samples was examined. The results indicate that ethylene oxide polymerized to polyethylene...
Effects of Relative Humidity on the Basal Expansion of Mg-Smectite Equilibrated with Ethylene Glycol at Low Vapor Pressure
Basal expansion Ethylene glycol Relative humidity Smectite X-ray powder expansion

2012/1/6
The effects of relative humidity (RH) on the expansion of Mg-smectite, equilibrated with low vapor pressure of ethylene glycol (EG), was studied. Four smectite samples were equilibrated with EG vapor ...
Fourier-Transform Infrared Study of Ethylene Glycol Monoethyl Ether Adsorbed on Montmorillonite: Implications for Surface Area Measurements of Clays
Adsorption Attenuated total reflectance spectroscopy Ethylene glycol monoethyl ether Infrared spectroscopy Molecular configuration Montmorillonite
font style='font-size:12px;'>
2011/11/25
Abstract: Infrared spectra of 2-ethoxyethanol (ethylene glycol monoethyl ether, EGME) adsorbed on Camontmorillonite were obtained using diffuse-reflectance infrared-Fourier-transform (DRIFT) and atten...
Adsorption of Ethylene Glycol on Amine-Substituted Montmorillonites
Adsorption Amine Ethylene glycol Expansion Montmorillonite
font style='font-size:12px;'>
2011/11/22
Abstract: To determine the reason why the adsorption of ethylene glycol on organo-smectites does not result in an expansion along the c-axis of the clays, smectites containing relatively small organo-...
Potassium- and Ammonium-Treated Montmorillonites. I. Interstratified Structures with Ethylene Glycol and Water
Ethylene glycol complex Interstratification Layer charge Mixed layer Montmorillonite
font style='font-size:12px;'>
2011/11/22
Abstract: Monoionic K- and NH4-smectites saturated with ethylene glycol form mixed-layer structures which usually consist of three kinds of layers: a 10-Å, non-expanded layer; a 14-Å, part...
