MODIFICATION OF FIBROUS SILICATES SURFACES WITH ORGANIC DERIVATIVES – AN INFRARED SPECTROSCOPIC STUDY
FIBROUS SILICATES SURFACES ORGANIC DERIVATIVES
2011/11/7
This contribution explores the interaction of the fibrous silicates, palygorskite, sepiolite and chrysotile with a wide range of organic agents. Infrared spectroscopy (IR) methods are essential for th...
Selective Gas Adsorption by Amorphous Clay-Mineral Derivatives
Amorphous Derivative Gas Adsorption Gas Separation Halloysite Kaolinite Montmorillonite Potassium Fluoride CMS Source Clay SAz-1 Specific Surface
2011/12/7
Abstract: Amorphous derivates prepared by aqueous reaction of various aluminosilicate clay minerals with concentrated KF solution at 80–110°C were studied for their gas adsorption properties. The four...
Preparation and Characterization of Two Distinct Ethylene Glycol Derivatives of Kaolinite
Ethylene glycol Interlamellar modification Kaolinite
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...
The Intercalation of Kaolinite by Alkali Halides in the Solid State: A Systematic Study of the Intercalates and Their Derivatives
Alkali halide Intercalate Kaolinite Structure Synthesis XRD
2011/12/1
Abstract: Kaolinite: alkali halide intercalates have been successfully prepared by grinding the salt with kaolinite in the absence of water. Rate of intercalation is shown to correlate negatively with...
Structural Characterisation of Kaolinite:NaCl Intercalate and its Derivatives
FTIR Intercalate Kaolinite NaCl NMR Structure Synthesis XRD
2011/12/31
Kaolinite:NaCl intercalates with basal layer dimensions of 0.95 and 1.25 nm have been prepared by direct reaction of saturated aqueous NaCl solution with well-crystallized source clay KGa-1. The inter...
Formation of Organic Derivatives of Boehmite by the Reaction of Gibbsite with Glycols and Aminoalcohols
Amino alcohol Boehmite Gibbsite Glycol Infrared spectroscopy Organic derivative X-ray powder diffraction
2011/12/31
The reaction of gibbsite in various organic solvents at 250°–300°C under spontaneous vapor pressure of the solvents was examined. Glycols and aminoalcohols afforded the organic derivatives of boehmite...
Organomineral Derivatives Obtained by Reacting Organochlorosilanes with the Surface of Silicates in Organic Solvents
Organomineral Derivatives Surface of Silicates Organic Solvents
2011/11/18
Abstract: Stable organomineral derivatives are formed by reaction of organochlorosilanes with certain phyllosilicates. Organosiloxyl functions are grafted on silanol groups present at external mineral...
