Abstract We present the density and surface tension of binary mixtures n-octane, n-nonane and n-decane with 1-nonanol in the entire composition range at atmospheric pressure. The surface tension is measured from 293.15 K to 313.15 K while the density is measured from 293.15 to 323.15 K. Densities are obtained from a vibrating tube densimeter and surface tensions are from a drop volume tensiometer. Excess molar volumes and surface tension deviations are calculated from the experimental measurements and they are represented using Redlich-Kister type equations. Surface entropy and enthalpy are calculated using the temperature dependence of the surface tension.

1-壬醇 + 正辛烷、+ 正壬烷和 + 正癸烷的二元混合物的密度和表面张力从 (293.15 到 323.15) K 在 P = 0.1 MPa

摘要 我们介绍了正辛烷、正壬烷和正癸烷与 1-壬醇的二元混合物在大气压下在整个组成范围内的密度和表面张力。表面张力测量范围为 293.15 K 至 313.15 K，而密度测量范围为 293.15 至 323.15 K。密度来自振动管密度计，表面张力来自液滴体积张力计。过量摩尔体积和表面张力偏差是根据实验测量计算的，它们使用 Redlich-Kister 类型方程表示。使用表面张力的温度依赖性计算表面熵和焓。
