摘要
采用静态方法测定了苯乙酮在超临界二氧化碳(scCO2)中的溶解度，温度分别为313.15、323.15、333.15和343.15K，压力范围为10 ~ 28 MPa。采用基于密度的模型(Chrastil和Del valle - Aguilera模型)和Peng-Robinson状态方程(PR-EOS)，结合二次和StryjekVera组合规则对实验数据进行关联。计算得到的溶解度数据与实验得到的溶解度数据具有良好的相关性。Chrastil模型和Del Valle - Aguilera模型的平方误差和(SSE)分别为0.38%和0.37%;二次组合规则的Peng-Robinson状态方程为9.07%，Stryjek-Vera组合规则的Peng-Robinson状态方程为4.00%。
Solubility of Acetophenone in Supercritical Carbon Dioxide
The solubility data of acetophenone in supercritical carbon dioxide (scCO2) were measured using a static method at several temperatures (313.15, 323.15, 333.15, and 343.15K) and pressures ranging from10 MPa to 28 MPa. The density based models (Chrastil and Del valle– Aguilera models) and the Peng-Robinson equation of state (PR-EOS) with quadratic and StryjekVera combining rules were employed to correlate the experimental data. Good correlations between the calculated and experimental solubility data were obtained. The sum of squared errors (SSE) are 0.38 % and 0.37 % for Chrastil and Del Valle – Aguilera models, respectively; and 9.07 % for Peng-Robinson equation of state with quadratic combining rule and 4.00 % for Peng-Robinson equation of state with Stryjek-Vera combining rule.
