Coulometric determination of organic compounds. III. Determination of some phenoxazones by titanometric coulometry
نویسنده
چکیده
Conditions have been found for the determination of some phenoxazones by titanometric coulometry using platinum electrode to generate Ti(III) ions, while the point of equivalency was recorded potentiometrically. It has been found, that correct and accurate results can be obtained when the amount of ethanol in the coulometric vessel is within 2—7 ml and the amount of the substance determined is 0.2—0,6 mg in 50—100 ml. Acetone was found a suitable solvent in the determination of 9-diethylaminobenzo[a]phenoxaz-5-one.

The acidity constants of some synthesized protonated pyrazolo quinazoline compounds were determined potentiometrically at ionic strength of 0.1 M in DMF: water (60:40 v/v) system at different temperatures (298.15 K to 318.15 K). The pKa values have been found to increase with increasing electron-donating nature of substitutions. Some thermodynamics parameters such as enthalpy (ΔH°), Gibb’s free...
متن کاملTHE ANODIC OXIDATION OF BASES IN THE SOLVENT no-CRESOL
Acid-base titrations can be carried out successfully in the solvent ??Icresol’. This is important for the determination of the acid or base content of some polymers for which ~cresol is a good solvent. The study of acid-base coulometry in nr-cresol was started because of the several advantages offered by coulometry: greater sensitivity, no problems with unstable titrants, and no need for standa...
متن کاملElectrooxidation of iodide in the presence of 4-hydroxycoumarin: application to a simple coulometric titration of 4-hydroxycoumarin.
The electrochemical oxidation of iodide ion in the presence of 4-hydroxycoumarin (1) was studied using cyclic voltammetry and controlled-potential coulometry. The result indicates that the resulting iodine takes part in a halogenation reaction and reacts with 4-hydroxycoumarin (1). According to the obtained results, a new and simple coulometric titration method with potentiometric end-point det...
متن کاملDevelopment of a simple column electrode for sensitive and rapid coulometry.
A simple column electrode, S-CE, with a glassy carbon fibers working electrode stuffed into a Teflon tube was developed. The current-potential curves for the reductions of [Fe(CN)(6)](3-) and Fe(3+) observed at the S-CE were analyzed based on a theory for those at an ordinary column electrode. A quantitative electrolysis was performed at the S-CE rapidly within 20 s. An accurate and precise cou...
