The solubility of carbon dioxide in two solvents, 2,5-dimethylfuran and methyl levulinate, were measured to high pressure, up to 9.1 MPa, at three different temperatures (283.15, 303.15 and 323.15) K. The new data were measured using both the isothermal synthetic technique and the variable volume synthetic method. Two methods were utilised to provide a level of data validation. The uncertainties in the measured data were critically estimated. The experimental phase equilibrium data were modeled using the Peng-Robinson equation of state and the Wong-Sandler mixing rule with a single set of binary interaction parameters for each system. The data indicated that the solubility of carbon dioxide in both 2,5-dimethylfuran and methyl levulinate at high pressures was relatively low, suggesting a low capacity of these biofuels to dissolve carbon dioxide at high pressure.

生物燃料中二氧化碳溶解度的高压相平衡：2,5-二甲基呋喃和乙酰丙酸甲酯的实验和热力学见解


在三种不同温度（283.15、303.15 和 323.15）K 的高压（高达 9.1 MPa）下测量了二氧化碳在两种溶剂（2,5-二甲基呋喃和乙酰丙酸甲酯）中的溶解度。新数据是使用等温合成技术和变体积合成方法。使用两种方法来提供一定程度的数据验证。对测量数据的不确定性进行了严格估计。使用 Peng-Robinson 状态方程和 Wong-Sandler 混合规则对每个系统的实验相平衡数据进行建模，并使用一组二元相互作用参数。数据表明，高压下二氧化碳在2,5-二甲基呋喃和乙酰丙酸甲酯中的溶解度相对较低，表明这些生物燃料在高压下溶解二氧化碳的能力较低。
