摘　　要：本文用高效液相色谱法研究了[Pt(TMDACP)I_2]和[Pt(TMDACP)(Cl-Ac)_2](TMDA是1,2,2-三甲基-1,3-二氨基环戊烷,Cl-Ac是氯乙酸根)的配体交换反应,测得20±0.1℃二级速率常数和平衡常数分别为(8.67±0.37)×10^(-3)mol^(-1)dm^3s^(-1)和0.572±0.008。The second-order rate constant and equilibrium constant of the ligand exchange reaction: [ Pt(TMDACP)I2] +[ Pt(TMDACP)(Cl-Ac)2] 2[ Pt(TMDACP)I(Cl-Ac)] (TMDACP is 1,2,2-trimcthyl-l, 3-diaminecyclopentane, Cl-Ac is chloroacetate) was determined by means of high performance liquid chromatography. At 20() in mcthanol I dichloromethanc =1:9, the rate constant and equilibrium constant are (8.67±0.37)×10-3mol-1 dm3s-1and 0.572±0.008 respectively.
