The conductometric titration of carboxylic and phenolic acids in non-aqueous solutions

Conductometric titrations of polyprotic acids in nonaqueous mixed solvents. Effects of temperature and composition of the solvent mixture

“…A temperature increase induces chair-shaped character of the curves, so that also the curves obtained in Gliem solutions, which are associated at low temperatures with N curves, turn to chair shape. This behavior, in disagreement with the literature observations (14), could be justified on the basis of the amphiprotic properties of the solvents under study, in particular of Gliem.…”

Resolution of mixtures of organic acids by conductometric titrations in 2-methoxyethanol

“…Several authors (2)(3)(4)(5)(6) have reported the presence of spectral interferences in line source absorption spectrometry (AAL). The three most common types of spectral interferences in atomic absorption spectrometry (AAS) are those due to (1) background absorption, (2) the presence of nonanalyte absorbing lines within the spectral region viewed for background correction, and (3) direct absorption overlap (7).…”

“…The titrations reported in this paper were mainly done under the experimental conditions used in the previous study (1) and the present results pertain to these conditions only. In the same way we have restricted our study to titrations at room temperature although, as reported in the literature (3), in some cases higher temperatures might be favorable.…”

Effects of hydrogen bonding and homoconjugation on the titration curves of a synthetic polynuclear phenolic compound in non-aqueous solvents

“…Van Meurs and Dahmen (16) showed that dielectric constant of the solvent and size of cation of titrant base play an important role in getting a particular shape of the titration curve. Therefore, it was considered of interest to vary the dielectric constant of the solvent by mixing with a solvent of low dielectric constant, such as benzene, and to study its influence on the nature of titration curves.…”
