The densities of aqueous mixtures of aminoethylethanolamine (CAS #000111-41-1) were measured over the entire compositional range at temperatures of 283.15–343.15 K. The results of these measurements were used to calculate excess molar volumes and isobaric thermal expansion coefficients, and partial molar and apparent molar volumes and excess isobaric thermal expansion coefficients were subsequently derived. The excess molar volumes were correlated as a function of the mole fraction using the Redlich–Kister equation. Temperature dependences of the Redlich–Kister coefficients are also presented. The partial molar volumes at infinite dilution of AEEA in water were determined using two different methods. In addition, the solution density was correlated using a Joubian–Acree model. Aqueous solutions of AEEA exhibit similar properties to the aqueous solutions of other alkanolamines (like monoethanolamine) used in acid gas sweetening.

283.15 至 343.15 K 温度下氨基乙基乙醇胺水溶液的密度、过量摩尔体积和热膨胀系数

在 283.15–343.15 K 的温度下，在整个组成范围内测量氨基乙基乙醇胺的水性混合物 (CAS #000111-41-1) 的密度。这些测量结果用于计算过量摩尔体积和等压热膨胀系数，以及随后推导出偏摩尔体积和表观摩尔体积以及过量的等压热膨胀系数。使用 Redlich-Kister 方程将过量摩尔体积关联为摩尔分数的函数。还介绍了 Redlich-Kister 系数的温度依赖性。AEEA 在水中无限稀释时的偏摩尔体积使用两种不同的方法确定。此外，使用 Joubian-Acree 模型将溶液密度关联起来。
