Determination of sulfur compounds in hydrotreated transformer base oil by potentiometric titration.
A method was developed to analyze the distribution of sulfur compounds in model sulfur compounds by potentiometric titration, and applied to analyze hydrotreated transformer base oil. Model thioethers were oxidized to corresponding sulfoxides by tetrabutylammonium periodate and sodium metaperiodate, respectively, and the sulfoxides were titrated by perchloric acid titrant in acetic anhydride. T...
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
متن کاملDetermination of pKa values of alendronate sodium in aqueous solution by piecewise linear regression based on acid-base potentiometric titration☆
As a mono-sodium salt form of alendronic acid, alendronate sodium presents multi-level ionization for the dissociation of its four hydroxyl groups. The dissociation constants of alendronate sodium were determined in this work by studying the piecewise linear relationship between volume of titrant and pH value based on acid-base potentiometric titration reaction. The distribution curves of alend...
متن کاملThe Role of Corrosive Sulfur in Transformers and Transformer Oil
Corrosive sulfur and the effect that it has in transformer systems can be significant. The extent of the corrosion damage caused by sulfur, if left unchecked, can be so severe as to cause failure of the apparatus. The problems with corrosive sulfur have been recognized for quite some time. As early as 1948, F.M. Clark and E.L. Raab [1] issued a report on the subject for method development withi...
متن کاملIodimetric Titration of Sulfur Compounds in Alkaline Medium
The possibilities of application of iodine as a titrant in determination of sulfur compounds have been presented. The influence of the reaction medium, the nature of compounds, and the thiolthione tautomerism on the reaction stoichiometry of sulfur compounds with iodine has been discussed. The conditions of volumetric titration with visual and potentiometric end-point detection and coulometric...
