摘要： 气液色谱法是研究酸碱相互作用热力学性质的有效方法之一。文献[1～3]利用气液色谱法测量了Ni(THDD)2、Ni[(C8H17O)2PS2]2与含氮有机碱加合反应的平衡常数、标准焓变和标准熵变值,得到了与光谱法相一致的结果。作为酸碱加合反应研究的一部分,本文测定了Ni[(C8H17O)2PS2]2与醛类化合物的热力学参数。

Abstract: The thermodynamic properties of adduction reaction of Ni[(C8H17O)2PS2]2 and CH3CHO, C2H5CHO, n-C3H7CHO and n-C4H9CHO were studied by GLC method. The equilibrium constants were determined between 333～363K and described by the emperical equation: 1gK = - 0.2087 - 0. 9209 Nc + (291. 9 + 265. 1 Nc)/T ΔH and ΔS were calculated by the least square method. It was found that - ΔH and - ΔS increased linearly with the increase of number of carbon in aldehydes: -ΔH=5. 59 + 5. 08 Nc (kJ/mol), -ΔS=3. 39 + 17. 63 Nc(J/K ·mol). The nature of adduct bonds was explained by electro-static model.
