摘要
在 phenol+ethanol 的碳一氧化物的溶解度在提高的压力混合了溶剂在这篇文章被报导。试验性的结果在 phenol+ethanol 混合物在公司的溶解度上揭示了压力的影响。这些混合物是为碳一氧化物的更差的溶剂。公司的溶解度是压力的线性功能，并且扩大亨利的常数在酚的不同集中被介绍。状态的立方的 Soave-Redlich-Kwong 方程被用来相关试验性的煤气的液体平衡数据并且同时预言公司的溶解度，二进制相互作用参数， kij 为合作酚，合作乙醇和酚乙醇系统被恰当的试验性的 GLE 数据在 303.15 K 并且在 2.0 鈥? .0 MPa 估计。因此，一个模型被建议因为在 phenol+ethanol 的公司的溶解度混合了溶剂。在与建议模型一起的试验性、计算的溶解度之间的协议是相当令人满意的。
The solubility of carbon monoxide in phenol＋ethanol mixed solvents at elevated pressures is reported in this article. The experimental results revealed the influence of pressure on the solubility of CO in phenol＋ethanol mixtures. These mixtures are a poorer solvent for carbon monoxide. The solubility of CO is a linear function of pressure, and the extended Henry＇s constants were presented at different concentrations of phenol. The cubic Soave-Redlich-Kwong equation of state was used to correlate the experimental gas liquid equilibrium data and to predict the solubility of CO. At the same time, the binary interaction parameters, kO, for CO-phenol, CO-ethanol and phenol-ethanol systems were estimated by fitting experimental GLE data at 303.15 K and at 2.0-9.0 MPa. Hence, a model was suggested for the solubility of CO in phenol＋ethanol mixed solvents. The agreement between experimental and calculated solubilities with the proposed model was rather satisfactory.
