本文用气液色谱法及混合过程体积的变化研究C_8芳烃与环丁砜的分子络合作用,用参考柱法和混合柱法测定了五种C_8芳烃与环丁砜的络合常数, 研究了C_8芳烃与环丁砜和丙二醇-1,2-碳酸酯的二元系超额体积,环丁砜与五种C_8芳烃构成的体系均有强烈的体积收缩效应,苯乙烯与环丁砜体系尤其明显,芳烃与丙二醇-1,2-碳酸酯构成的体系收缩程度远远低于前者。
In this paper, the molecular complexation of C_8 aromatics with sulfolane was studied by means of gas-liquid chromatography and the change of volume during the mixing process. The complexation constants of five C_8 aromatics with sulfolane were determined by reference column method and hybrid column method. And propylene glycol-1,2-carbonate excess volume of the binary system, sulfolane and five C_8 aromatics composition of the system has a strong effect of volume shrinkage, styrene and sulfolane system is particularly evident, aromatic and propylene glycol-1,2-carbon acid Ester system contraction is much lower than the former.
