Solubilities of 2-naphthalenesulfonic acid monohydrate and sodium 2-naphthalenesulfonate in sulfuric acid solution and their application for preparing sodium 2-naphthalenesulfonate

Transactions of Tianjin University, 2016
The solubilities of 2-naphthalenesulfonic acid monohydrate and sodium 2-naphthalenesulfonate in sulfuric acid solutions were measured at temperatures ranging from 278.15 to 338.15 K by using a dynamic method. The concentration of sulfuric acid solution ranged from 0 to 80wt%,.

Biological and electrochemical oxidation of naphthalenesulfonates

Journal of Chemical Technology & Biotechnology, 2005
AbstractA biofilm airlift suspension (BAS) reactor and an undivided flow cell equipped with a boron‐doped diamond (BDD) anode and a stainless‐steel cathode were used to investigate the effects of varying operating conditions on process performance in the biological and electrochemical oxidation of a mixture of naphthalenesulfonates contained in the ...

The interaction of 8‐anilino‐1‐naphthalenesulfonate with polylysine and polyarginine

Biopolymers, 1977
AbstractComparative studies on the interaction of 8‐anilino‐1‐naphthalenesulfonate (ANS) with polylysine and polyarginine have been made by equilibrium dialysis and fluorescence or circular dichroism measurements, to investigate the structural characteristics of the polypeptides.

Use of 8-Anilino-1-Naphthalenesulfonic Acid in Radioimmunoassay of Triiodothyronine

Journal of Pharmaceutical Sciences, 1974
The rationale for the use and effects of 8-anilino-1-naphthalenesulfonic acid in the radioimmunoassay of triiodothyronine is discussed. Historical background for the use of fluorescent probes, such as 8-anilino-1-naphthalenesulfonic acid, to study protein sites is outlined.

Biotransformation of 1-naphthalenesulfonic acid by the green alga Scenedesmus obliquus

Archives of Microbiology, 1997
Under sulfate limitation, axenic batch cultures of the green alga Scenedesmus obliquus metabolized 1-naphthalenesulfonic acid and partially used the sulfonate as a source of sulfur. The main metabolite, 1-hydroxy-2-naphthalenesulfonic acid, which was not metabolized further in the algal culture, was formed by hydroxylation of the substrate in position ...

Escherichia coli phosphofructokinase: Inhibition by 8-anilino-1-naphthalenesulfonate

Archives of Biochemistry and Biophysics, 1975
Abstract Phosphofructokinase was purified 1200-fold from extracts of Escherichia coli B. Kinetic studies of the enzyme were carried out in the presence of the fluorescent dye 8-anilino-1-naphthalenesulfonate (1,8-ANS). 1,8-ANS was competitive with ATP and an uncompetitive inhibitor with respect to fructose-6- P .

Some naphthalenesulfonic acids as sulfur sources for the green microalga,

Chemosphere, 1987
Scenedesmus obliquus is capable to utilise various naphthalenesulfonic acids, including disulfonic acids, as sources of sulfur. After precultivation in sulfate medium, the adaptation to the naphthalene sulfonates was followed, and the growth rate of the adapted algae was determined.

Photo-induced dimerization of 1-anilino-8-naphthalenesulfonate

Journal of Photochemistry and Photobiology A: Chemistry, 1992
Abstract 1-Anilino-8-naphthalenesulfonate (ANS) was observed to undergo a number of photochemical processes, including ionization, dimerization and loss of sulfonate. A mechanism that involves monophotonic ionization is proposed for the photo-induced dimerization of ANS.
