Protonation constants of oxalate (ox2-) were obtained, by potentiometric measurements, in NaCl, KCl and tetraethylammonium iodide aqueous solutions in the ranges 5 ⩽ T ⩽ 50°C and 0 ⩽ I ⩽ 1 mol dm−3. The differences in protonation constant values were explained by a complex formation model assum...detailed
The reducing action of some aliphatic and aromatic hydrocarbon derivatives on the oxides of Me, W, Ti, Zr, Nb and Ta was compared to that of graphite powder. The investigation showed that among the organic compounds studied tetraethylammonium iodide gives a better separation of the volatile elem...detailed
The data regarding the protonation of 22-(mono-, di-,…, penta-) carboxylic acids in aqueous tetraethylammonium iodide at different ionic strengths 0detailed
The interactions of amino acids glycine, l-alanine and l-valine with tetraethylammonium iodide (TEAI) as a function of temperature have been investigated by a combination of volumetric and acoustic measurement. Densities (ρ) and ultrasonic speeds (u) of amino acids in aqueous solutions of TEAI ...detailed
Knowledge of thermodynamic properties of substituted amino acids in aqueous medium can provide valuable information regarding the stabilisation mechanism of proteins. In this study, we report the density and ultrasonic speeds of N-acetyl glycine in (0.03, 0.05, 0.1, 0.15 and 0.2) mol ⋅ kg−1 aque...detailed
