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2．62×10-3 mol/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．

Hexyl methyl malonate was synthesized , its structure was determined and its solubility was measured at different temperatures (313 K, 333 K and 353 K) and pressures from 8.5 MPa to 13.6 MPa in supercritical carbon dioxide .The solubility data were correlated by Bartle and Chrastil semiempirical model and the partial molar volume were calculated by Kumar-Johnston theory.The results indicated that the solubility of C 10H18O4 was as high as 2.62 ×10 -3 mol/L at 8.5 MPa and 313 K , which showed good correlation with Bartle and Chrastil model and AARD was 3.28 % ~58.65 % and 0.0068 %~27.7 %respectively.Its partial molar volume was -5708.79,-1665.36,-707.43 cm3/mol at 313, 333, 353 K respectively .
