设计合成了甲氧羰基乙酸己酯,确定了其结构,在压力为8.5~18.6 MPa,温度为313~353 K测定了其在超临界CO2中的溶解度.并运用Bartle和Chrastil半经验模型对溶解度数据进行关联,由Kumar-Johnston理论计算其在超临界相中的偏摩尔体积.结果表明:甲氧羰基乙酸丁酯在8.5 MPa、313 K下溶解度高达2.62×10-3mol/L,与理论计算结果相关性良好,平均相对偏差分别为3.28%~58.65%和0.0068%~27.7%.在313,333,353 K温度下,其偏摩尔体积分别为-5708.79,-1665.36,-707.43 cm3/mol.
The structure of hexyl methoxycarbonylacetate was designed and synthesized, and its structure was determined. The solubility in supercritical CO2 was measured under the pressure of 8.5 ~ 18.6 MPa and the temperature of 313 ~ 353 K. The solubility of Data were correlated and their partial molar volumes in the supercritical phase were calculated by the Kumar-Johnston theory.The results showed that the solubility of butyl methoxycarbonyl acetate at 2.25 MPa and 313 K was as high as 2.62 × 10-3 mol / L, The results showed good correlation with average relative deviations of 3.28% -58.65% and 0.0068% -27.7%, respectively. The partial molar volumes at 313,333 and 353 K were -5708.79, -1665.36 and -707.43 cm3 / mol, respectively.
