| 摘要: 本文用气液色谱(GLC)法的保留值方法测定作为Lewis碱的脂肪醇和脂肪胺在固定液角鲨烷中的溶解平衡常数KR+、碱与作为Lewis酸的辣Ni[CF3COCHC(C4H4S)=NCH2]2配合物的表观平衡常数KR以及碱的真实加合常数K1,以LnK1对1/T作图求出了加合作用的热力学函数△H和△S值.它们和醇及胺中碳数n间存在线性关系。KR+和KR值随碳数的增加而增大,K1值随碳数的增加而减小。所有加合反应都是热的,熵值随着碳数的增加而减小。 |

| Abstract: Solubility constants of some Lewis bases (aliphatic alcohol and amine) in squalane (KR), the appearent and real adductive constants(KR and K1 of Lewis bases with Ni [CF3COCHC(C4H4S) =NCH2]2 in squalane solution were determinated by GLC. KR and KR increased with the increasing of carbon numbers, but K1 change oppositely.Thermodynamic parameters △H and △S were calculated by-RlnK>1/T. the linearrelationships Between these thennodynamic parameters and carbon numbers.were found. All adductive reaction were exothermal reaction. △S values is decreased with the increasing of carbon numbers. |
