中文摘要:
      设计合成了一系列双丙酮-D-葡萄糖(化合物1)衍生物,双丙酮-D-葡萄糖草酸甲酯(化合物2)、双丙酮-D-葡萄糖草酸乙酯(化合物3)、双丙酮-D-葡萄糖-丙二酸甲酯(化合物4),并将其用于超临界二氧化碳(scCO2)中溶解度的测定和关联研究.在压力范围(8.0~13.6 MPa)内对不同的温度(313, 323, 333 K)下的浊点进行测量,再用5种不同的理论半经验模型(Chrastil, KJ, SS, MST, JCF)对溶解度数据进行计算和关联分析,其结果与实验数据有较好的吻合度,JCF模型拟合效果最好,平均绝对相对偏差(AARD)最低,为3.13%~6.22%. 此外,还根据Kumar和Johnston理论计算了这4种化合物在超临界相中的偏摩尔体积,通过计算结果得其值在?6479.51~?630.65 cm3?mol-1.
英文摘要:
      A series of diacetone-D-glucose (compound 1) derivatives, (diacetone-D-glucose methyl oxalate (compound 2), diacetone-D-glucose ethyl oxalate (compound 3), diacetone-D-glucose methyl malonate (compound 4), were designed and synthesized as carbon dioxide (CO2)-philic compounds for the measurement and correlation of their solubilities in supercritical carbon dioxide (scCO2). The cloud point was measured at different temperatures of 313, 323, 333 K over the pressure range of 8.0 to 13.6 MPa, then the solubility data were calculated and correlated by five different theoretical semi-empirical models (Chrastil, KJ, SS, MST, JCF). The results showed satisfactory agreements with the experimental data, with the JCF model providing the best fitness, which gave out the lowest average absolute relative deviation (AARD) from 3.13% to 6.22%. Furthermore, the partial molar volumes of these four compounds in the supercritical phase were also calculated according to the Kumar and Johnston theory, with the value between ?6479.51 and ?630.65 cm3?mol-1.
