In this work, we present new density measurements of benzyl alcohol and 1-heptanol from 283.15 to 363.15 K up to 65 MPa and ±2-octanol from 283.15 to 358.15 K up to 50 MPa. The density was obtained using a vibrating tube densimeter employing the Forced Path Mechanical Calibration method. The combined standard density uncertainty is 0.00035 g·cm^–3 for benzyl alcohol and 1-heptanol, while for ±2-octanol (racemic mixture), it is 0.00045 g·cm^–3. The density data are correlated with a multiparametric equation of state explicit in the compressibility factor. We have correlated the density with the equation of state within an average absolute percentage deviation of (0.058, 0.085, and 0.077) % for benzyl alcohol, ±2-octanol, and 1-heptanol, respectively. Isobaric expansibility and isothermal compressibility are calculated from the multiparametric equation within an average absolute percentage deviation of 6% from values reported in the literature.

苯甲醇、±2-辛醇（外消旋混合物）和 1-庚醇在 283.15 至 363.15 K 压力高达 65 MPa 下的 P–ρ–T 数据和导出的体积特性

在这项工作中，我们提出了从 283.15 至 363.15 K 至 65 MPa 的苯甲醇和 1-庚醇以及从 283.15 至 358.15 K 至 50 MPa 的±2-辛醇的新密度测量。使用采用强制路径机械校准方法的振动管密度计获得密度。苯甲醇和1-庚醇的组合标准密度不确定度为0.00035 g·cm ^{–3 ，而±2-辛醇（外消旋混合物）的标准密度不确定度为0.00045 g·cm –3}。密度数据与压缩因子中明确的多参数状态方程相关。我们将苯甲醇、±2-辛醇和 1-庚醇的密度与状态方程关联起来，平均绝对百分比偏差分别为 (0.058、0.085 和 0.077)%。等压膨胀率和等温压缩率是根据多参数方程计算得出的，与文献报道的值的平均绝对百分比偏差为 6%。
