Abstract (English)

Dielectric relaxation spectra have been measured for aqueous solutions of sodium n-alkylcarboxylates (Cm-1H2m-1COONa, where m = 1-5), trifluoroacetate, benzoate, methylsulfate, and methanesulfonate over a wide range of frequencies (0.2 ≤ v / GHz ≤ 89) up to the saturation limit at 25°C. Measurements were also made on sodium acetate(aq) at 15 ≤ T/°C ≤ 35. The spectra were best described by a ...

Translation of the abstract (German)

Bei 25 °C wurde über einen weiten Frequenzbereich (0.2 ≤ v / GHz ≤ 89) das dielektrische Relaxationsverhalten der Natriumsalze von n-Alkylcarboxylaten (Cm-1H2m-1COONa mit m=1-5), Natriumtrifluoracetat, -benzoat, -methylsulfat und –methansulfonat in wässrigen Lösungen bis zur Sättigungsgrenze bestimmt. Natriumacetatlösungen wurden zusätzlich als Funktion der Temperatur im Bereich von 15-35 °C ...
