Surface tension at 277.15, 283.15, 288.15, 293.15, 298.15, and 303.15 K and density at 277.15, 283.15, 288.15, 293.15, 298.15, 303.15, and 308.15 K for ethylene glycol monobutyl ether–water mixtures were measured. Experimental surface tension vs concentration data was described utilizing the Volmer surface equation of state, coupled with the Gibbs adsorption isotherm, which provides two nonempirical fitted parameters: the activity coefficient at infinite dilution of the bulk and the two-dimensional virial coefficient. Density experimental data shows negative excess volume deviations through all composition range, with abnormal behavior around 0.02 in mole fraction of the solute, which tends to diminish as temperature increases. A Redlich–Kister type model for strongly associated components was used to describe excess volume behavior.

277.15至308.15 K的乙二醇单丁醚-水混合物的表面张力和密度

对于乙二醇单丁醚-水混合物，测量了277.15、283.15、288.15、293.15、298.15和303.15 K的表面张力以及277.15、283.15、288.15、293.15、298.15、303.15和308.15 K的密度。利用Volmer表面状态方程，结合Gibbs吸附等温线描述了表面张力与浓度的实验数据，该方程提供了两个非经验拟合参数：在无限稀释的体积中的活度系数和二维病毒系数。密度实验数据显示，在所有成分范围内，负的过量体积偏差都为负值，异常行为约为0.02（以溶质的摩尔分数计），随着温度的升高，这种现象趋于减少。强烈关联的组件的Redlich–Kister类型模型用于描述过量的体积行为。
