THE ANODIC OXIDATION OF BASES IN THE SOLVENT no-CRESOL
نویسنده
چکیده
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 standardization of titrants. Preliminaryexperiments in which constant-current coulometric titrations were carried out in solutions of tctraethylammonium perchlorate in m-crcsol showed that theelectrochemicalgenerationofbase(base(,~z-cresolate)at platinum electrodes does occur with lOOo/o current efficiency. However, in these experiments, generation of acid did not occur with lOO”/, current efficiency. The present study of the anodic oxidation of bases in ,n-cresol was undertaken to establish conditions for 100°A current eficiency in the generation of acid in mcresol.
