Benzyl alcohols are an important class of aromatic alcohols used in the fine chemical and pharmaceutical industries which can be found in extracted bio-oils produced from the thermochemical liquefaction of lignocellulosic biomass.

Equation-of-state (EOS) models can be used to describe the vapour-liquid equilibrium (VLE) to support supercritical fluid extraction (SFE) studies of key compounds from bio-oils, but ideally require experimentally determined binary VLE data at appropriate conditions of temperature and pressure.

In this study, high-pressure solubility data of benzyl alcohol in supercritical carbon dioxide (scCO₂) is reported. Data has been determined experimentally at temperatures of 313 K, 333 K and 353 K and at pressures up to 284 bar. Data was used to validate and support existing published solubility data. It was shown that the literature VLE data regression to the Peng-Robinson-Boston-Mathias (PR-BM) model was good in fitting benzyl alcohol solubility data determined both in this study and in previous literature.

苯甲醇是在精细化工和制药行业中使用的一类重要的芳香族醇，可以从木质纤维素生物质的热化学液化产生的提取的生物油中找到。

状态方程（EOS）模型可用于描述蒸气-液体平衡（VLE），以支持对生物油中关键化合物的超临界流体萃取（SFE）研究，但理想情况下，需要在适当条件下通过实验确定的二元VLE数据温度和压力。

在这项研究中，报告了苯甲醇在超临界二氧化碳（scCO ₂）中的高压溶解度数据。已经在313 K，333 K和353 K的温度以及最高284 bar的压力下通过实验确定了数据。数据用于验证和支持现有已发布的溶解度数据。结果表明，对Peng-Robinson-Boston-Mathias（PR-BM）模型的文献VLE数据回归很好地拟合了本研究和先前文献中确定的苯甲醇溶解度数据。
