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...
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...
Organic Derivatives of Attapulgite—I. Infrared Spectroscopy and X-Ray Diffraction Studies
Attapulgite Organic Derivatives X-Ray Diffraction
2012/2/13
Highly significant differences are observed between the methyl derivatives of attapulgite, produced when this mineral is reacted with (CH3)2Si(OC2H5)2, in the presence or in absence of HCl. In the fir...
