测定了硫酸铵、硫酸钾和硫酸铝在水和水+（5%、10%、15%和20%）N，N-二甲基甲酰胺混合溶剂中的粘度，温度为298.15和308.15 K，压力为常压。研究的摩尔浓度范围为（0.0081 - 0.1000）mol·kg−1。用Jones-多尔方程分析了粘度数据，并计算了B系数。根据这些盐在水和水+ DMF混合溶剂中的结构生成/断裂行为解释了结果。
Viscosities of ammonium sulfate, potassium sulfate, and aluminum sulfate in water and water + (5 %, 10 %, 15 %, and 20 %) N,N-dimethylformamide mixed solvent have been measured at T = (298.15 and 308.15) K and at atmospheric pressure. A molality range has been studied between (0.0081 and 0.1000) mol·kg−1. The viscosity data have been analyzed with the Jones−Dole equation, and B coefficients have been calculated. The results have been interpreted in terms of structure making/breaking behavior of these salts in water and water + DMF mixed solvents.
