Polypyrrole Doped with Alkyl Benzenesulfonates

Macromolecules, 2002
The properties of polypyrrole (PPy) are to a large extent determined by the condition of synthesis and especially by the counterion incorporated as dopant during synthesis. In this work, PPy doped with different alkyl benzenesulfonates are compared. The polymer films are prepared by constant current oxidation of pyrrole in aqueous solutions containing ...

Photocatalytic degradation of benzenesulfonate on colloidal titanium dioxide

Water Research, 2011
Titanium dioxide-mediated photocatalyzed degradation of benzenesulfonate (BS) was investigated by monitoring chemical oxygen demand (COD), total organic carbon (TOC) content, sulfate concentration, pH as well as the absorption and emission spectral changes in both argon-saturated and aerated systems. Liquid chromatography-mass spectrometry analysis was

Adsorption of sodium dodecyl benzenesulfonate onto coal

Journal of Colloid and Interface Science, 2003
The adsorption behavior of sodium dodecyl benzenesulfonate (NaDDBS) on a raw (as received) coal sample and its demineralized variety with 11.3% and 1.2% ash contents respectively has been studied. The samples have been characterized by their proximate analysis, particle size distribution, surface area, porosity, density, points of zero charge, etc ...

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 ...

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 ...
