A new high-pressure equilibrium cell to obtain data for systems containing fluids and solids is presented. By using the static synthetic method, an experimental unit was commissioned to obtain phase transition data at pressures up to 1000 bar, and temperatures ranging from 253 to 473 K. Measured phase transition data include new data for liquid-vapor, liquid-liquid, liquid-liquid-vapor, solid-liquid, and solid-liquid-liquid of CO₂ + n-hexadecane, CO₂ + n-eicosane, and CO₂ + n-tetracosane binary systems. Results are compared to those from literature and show that the new experimental cell setup presents a good performance and allows to explore regions where traditionally, accurate experimental data are scarce.

介绍了一种新的高压平衡单元，用于获取包含流体和固体的系统的数据。使用静态合成方法，委托实验装置获得压力高达1000 bar，温度范围为253至473 K的相变数据。 测得的相变数据包括液-汽、液-液、液体的新数据CO ₂ + 正十六烷、CO ₂ + 正二十烷和CO ₂ + 正二十烷二元体系的-液-气、固-液和固-液-液。结果与文献中的结果进行了比较，表明新的实验单元设置具有良好的性能，并允许探索传统上缺乏准确实验数据的区域。
