Experimental data of density have been measured for binary liquid mixtures containing {amines (n-butylamine, or s-butylamine, or t-butylamine, or diethylamine, or propylamine) + water}, over the entire range of composition at temperatures between 283.15 and 303.15 K, and atmospheric pressure. The density values enabled the determination of the thermal expansion coefficients. The excess molar volume, \({\text{V}}_{\text{m}}^{\text{E}}\), was calculated using the experimental data, from which a Redlich–Kister type polynomial was fit, enabling the determination of the partial molar volumes, the excess partial molar volumes, the apparent molar volumes and the excess partial molar volumes at infinite dilution. The \({\text{V}}_{\text{m}}^{\text{E}}\) values were also used to test the applicability of the Extended Real Associated Solution Model (ERAS Model). The results for the studied systems suggest that structural effects and chemical interactions must predominate over other possible effects. The magnitude of \({\text{V}}_{\text{m}}^{\text{E}}\) for the studies systems led to the following order: n-butylamine > propylamine > s-butylamine > diethylamine > t-butylamine.

密度的实验数据已测量了包含二进制液体混合物{胺（Ñ丁胺，或š丁胺，或吨丁胺，或二乙胺，丙胺或）+水}，过的组合物的整个范围内的温度和283.15之间303.15 K，大气压。密度值能够确定热膨胀系数。过量摩尔体积\({\text{V}}_{\text{m}}^{\text{E}}\)是使用实验数据计算的，从中拟合了 Redlich-Kister 型多项式, 能够确定部分摩尔体积、过量部分摩尔体积、表观摩尔体积和无限稀释时的过量部分摩尔体积。这\({\text{V}}_{\text{m}}^{\text{E}}\)值也用于测试扩展真实相关解决方案模型（ERAS 模型）的适用性。研究系统的结果表明，结构效应和化学相互作用必须优于其他可能的效应。研究系统的\({\text{V}}}_{\text{m}}^{\text{E}}\)的大小导致以下顺序：正丁胺 > 丙胺 >  s -丁胺 >二乙胺> 叔丁胺。
