摘要
气液色谱法是研究作为Lewis酸A的过渡金属配合物与作为Lewis碱的有机化合物B相互作用的热力学参数的有效方法,但以往工作大都采用非极性的直链角鲨烷作固定液。为将此法扩展到包含苯基配体的过渡金属配合物体系,我们采用一种新的固定液——多苄基联苯,测定了双(1,3)-二苯基丙二酮合铜(Ⅱ)与呋喃、噻吩的加合反应的热力学参数。
Using the GLC method, soluble equilibrium constant KR0 of Lewis bases furan C4H4O and thiophen C4H4S in the dibenzyl diphenyl solvent, and the apparent equilibrium constant KR for the interaction between the two Lewis bases and the Lewis acid transition metal complex 1,3-diphenyl-1,3-propanedione copper at various temperatures are determined. The equilibrium constant K1 corresponding to the adduct reaction of the two bases with the complex is also found, and obtain two empirical formulas as follows: (for furan) (for thiophen) By the thermodynamic formulawe further find the thermodynamic parameters △H and △S.
