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
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
Curve-fitting Dickite Infrared LO and TO Crystal Modes Micro-Raman OH bands SEM
2011/12/5
Abstract: The OH-stretching region in curve-fitted micro-Raman, photoacoustic and transmission IR spectra of St. Claire dickite was investigated. Polarized Raman spectra recorded from the (001) and (0...
Hydroxyl Deformation in Kaolins
Deformation Mode Dickite FT Raman Halloysite Hydroxyl Infrared Intercalation Kaolinite Libration Reflectance
2011/12/8
Abstract: The hydroxyl deformation modes of kaolins have been studied by Fourier transform (FT) Raman spectroscopy. Kaolinites showed well-resolved bands at 959, 938 and 915 cm−1 and an addition...
The Influence of Aluminum on Iron Oxides. Part XVI: Hydroxyl and Aluminum Substitution in Synthetic Hematites
Al substitution Cell-edge lengths Hematite LOI OH substitution X-ray intensity
2011/12/31
Synthetic hematites with Al substitutions between 0 and 18 mol % were synthesized at different temperatures and water activities. The cell-edge lengths a for different synthesis conditions decreased l...
Hydroxyl Orientations and Interlayer Bonding in Amesite
Amesite Fluorine Hydroxyl orientation Interlayer bonding Serpentine
2012/2/8
The hydroxyl orientations in the 2H2 polytype of amesite, Mg2Al(SiAl)O5(OH)4, have been determine by minimizing the electrostatic potential energy as a function of OH orientation. The angles, ρ, betwe...
Hydroxyl Orientations in 2:1 Phyllosilicates
Brittle Mica Energy Calculations Hydroxyl Orientation Mica Phyllosilicate
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
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
Iron Oxidation Structural Hydroxyl Layer Aqueous Suspensions Micaceous
2012/2/15
Four Na2S2O4-reduced Na-vermiculites, each with some trioctahedral mica interstratified, were oxidized with H2O2 at pH 6·5 and again reduced with Na2S2O4 in suspensions at pH 7·5–8·0. The layer charge...
Hydroxyl Stretching Frequencies of Synthetic Ni-, Al-, and Mg-Hydroxy Interlayers in Expanding Clays
Hydroxyl Frequencies of Synthetic Mg-Hydroxy Interlayers
2011/11/17
Abstract: Interlayers were produced in montmorillonite, vermiculite and hectorite in aqueous suspensions by precipitation from metal chloride salt, by hydrolysis of metal amalgams, and by slow hydroly...
