Preparation of Terminal Phenolic Hydroxyl Triazine Dendrimer and its Combination Tanning Properties with the Aluminum Salts
1,3,5-Benzenetriol Chrome-Tanning Assistant Cyanuryl Chloride Hyperbranched Polymer Leather
font style='font-size:12px;'>
2011/11/23
Terminal phenolic hydroxyl triazine dendrimer (HTHP) was prepared by putting cyanuryl chloride and 1,3,5-benzenetriol into acetone and then adding K2CO3 into the mixture as deacid reagent, which is ca...
Hydroxyl-Stretching Bands in Curve-Fitted Micro-Raman, Photoacoustic and Transmission Infrared Spectra of Dickite from St. Claire, Pennsylvania

2012/2/9
The hydroxyl orientations in 31 dioctahedral and trioctahedral 2:1 phyllosilicate structures have been determined by electrostatic energy calculations. These structures included micas, brittle micas, ...
The Influence of Hydroxyl Orientation, Stacking Sequence, and Ionic Substitutions on the Interlayer Bonding of Micas
Hydroxyl Orientation Stacking Sequence Ionic Substitutions Micas
font style='font-size:12px;'>
2012/2/13
Hydroxyl orientation has a major influence on the strength of the ionic interlayer bonding in micas because of the strong repulsion between the hydrogen and the interlayer cation (IC). In order to det...
Iron Oxidation and Reduction Effects on Structural Hydroxyl and Layer Charge in Aqueous Suspensions of Micaceous Vermiculites
