气液色谱法研究一些五员杂环和Ni[CF_3COCHC(C_4H_4S)=NCH_2]_2加合反应的热力学性质

STUDY ON THE THERMODYNAMIC PROPERTIES OF ADDITIVE REACTION FOR Ni[CF_3COCHC(C_4H_4S) =NCH_2]_2 WITH SOME FIVE-MEMBERED HETEROCYCLES BY GLC METHOD

用气液色谱法研究过一系列作为Lewis碱(B)的有机配体和作为Lewis酸(A)的配合物之间的加合作用.研究较多的碱已有脂肪醇、醚、酮、醛、脂及胶等.对生物体系中广为存在的杂环配体碱的工作还很少.本文着重研究噻吩,呋喃和吡咯这类小分子杂环配体和Ni[CF_3COCHC(C_4H_4S)=NCH_2]_2(以下简称A)配合物的加合反应. Ni[CF_3COCHC(C_4H_4S)=NCH_2]_2的合成参考文献.固定液角鲨烷系英国进口,

The solubillty constants K°R of some five-membered heterocycles i.e. furan, thiopheneand pyrrole, the apparent equilibrium constants KR and the stability constants K_1 of theseLewis bases with Lewis acid Ni [CF_3COCHC(C_4H_4S)=NCH_2]_2 in squalane solution aredetermined by GLC method. The thermodynamic parameters are calculated with the relation-RlnK_1～1/T. The results of the experiments have been analysed.
