中文摘要：

测定了温度为313~353 K、压力为9.6~16.3 MPa条件下,4,4＇-二异氰酸酯二苯甲烷（MDI）在超临界CO_2中的溶解度,运用Bartle和Chrastil半经验模型对溶解度数据进行了关联分析.结果表明：实验数据和理论数据吻合良好,平均值绝对相关偏差对Bartle模型在4.56%~10.68%,Chrastil模型为10.79%.根据Kumar和Johnston的理论算得MDI在该条件下的超临界CO2中的偏摩尔体积V_2.

英文摘要：

The solubility of 4,4＇-methylene diphenyl diisocyanate （MDI） in supercritical carbon dioxide were tested at temperatures from 313 K to 353 K and pressures over the range of 9.6 MPa to 16.3 MPa.The density-based correlation models proposed by Bartle and Chrastil were used to correlate the solubility data.The correlation results showed good consistency between the experimental and calculated data, and values of the average absolute relative deviation （AARD） were between 4.56% and 10.68 % for Bartle model, and 10.79 % for Chrastil model, respectively.Finally, the partial molar volume 2 of MDI were calculated in supercritical CO2 according to the Kumar and Johnston theory.
