NMR studies of uranyl benzenesulfonate solvation and phase diagram of uranyl benzenesulfonate-water-tributyl phosphate system

Journal of Radioanalytical and Nuclear Chemistry Articles, 1990
Uranyl hydration and solvation numbers of uranyl benzenesulfonate (BSU) aqueous-organic solutions have been determined by means of dynamic NMR spectroscopy technique. Three aqua-complexes have been found to exist in aqueous-acetone solution: [UO2 (U6H5SO3)2·4H2O] and [UO2(C6H5SO3)2·(H2O)n] where n=1 or 2 and anions are bridging bidentate.

THE HYDROLYSIS OF SUBSTITUTED METHYL BENZENESULFONATES IN WATER

Canadian Journal of Chemistry, 1966
Rate data and derived parameters for the hydrolysis of a series of para-substituted methyl benzenesulfonates are given. The introduction of such substituents has negligible effect on ΔCp≠, and the difference in rate is largely reflected in δXΔS≠.

High-Performance Nanopapers Based on Benzenesulfonic Functionalized Graphenes

ACS Nano, 2012
High-performance graphene nanopapers are prepared from an aqueous solution of functional graphenes with benzenesulfonic acid groups via covalent bonds. The formed hydrophobic graphene nanopapers showed the highest tensile strength of 360 MPa and Young's modulus of 102 GPa for samples with 13.7 wt % functional group and annealed at 150 °C. These samples

Effect of ion interactions on the IR spectrum of benzenesulfonate ion. Restoration of sulfonate ion symmetry in sodium benzenesulfonate dimer

Journal of Molecular Structure, 2016
Abstract Literature data concerning the assignment of IR spectra of benzenesulfonate salts that serve as model compounds for aromatic sulfonate-containing ionomers and polyelectrolytes have been analyzed. The structures and IR spectra of free benzenesulfonate ion and its potassium and sodium salts have been calculated in B3LYP/6-311G(d,p ...

Do enantiomers of benzenesulfonic acid exist? Electron diffraction and quantum chemical study of molecular structure of benzenesulfonic acid

Journal of Molecular Structure, 2012
Abstract Molecular structure of benzenesulfonic acid was studied by gas-phase electron diffraction and quantum chemical (B3LYP/cc-pVTZ, МР2/cc-pVDZ, МР2/cc-pVTZ) methods. On the base of mass spectrometric analysis it was found that saturated vapor at Т = 396(9) K is represented by only molecular species, monomeric benzenesulfonic acid.

4-Fluoro-2-(phosphonomethyl)benzenesulfonic acid monohydrate

Acta Crystallographica Section C Crystal Structure Communications, 2000
The title compound, C7H8FO6PS·H2O, contains both phospho­nic and sulfonic acid functionalities. An extensive network of O—H⋯O hydrogen bonds is present in the crystal structure. The three acidic protons are associated with the phospho­nate group. Two protons experience typical hydrogen-bond contacts with the sulfonate-O atoms, while the third has a ...

Kinetics of benzenesulfonates elimination by UV and UV/H2O2

Journal of Photochemistry and Photobiology A: Chemistry, 2004
Abstract The kinetics of elimination of eight benzenesulfonate derivatives (BS) have been studied in aqueous solution. Experiments were performed at 25 °C, at pH=6.0, in a batch photochemical reactor in the absence and the presence of hydrogen peroxide.

Decomposition of benzenediazonium fluoborate in benzenesulfonic esters and in acetophenone

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1958
1. Phenyl formed by the decomposition of benzenediazonium fluoborate in methyl and ethyl benzenesulfonates acts only on the alkoxysulfonyl group in these esters and in both cases gives phenyl benzenesulfonate. 2. In the decomposition of benzenediazonium fluoborate in acetophenone, 3′- and 4′-phenylacetophenones are formed in the ratio of
