摘要： 把载有金属盐(M)乙二醇(S)溶液的6201担体作为色谱柱,再将各种不饱和烃(U)分别注入色谱柱中,此时在液相中存在如下的配合平衡.

Abstract: The thermodynamic functions of complexation reactions for Ag(Ⅰ), Ni(Ⅱ)and Zn(Ⅱ )with some unsaturated hydrocarbons have been determined at 40℃ by gas-liquid chromatographic method and the results obtained arc as follows: For Ag (Ⅰ)-ethylene, formation constant K1=21.8, △H =-7.7 kcal/mole. △S=-18.5 cal/deg.mole; For Ag(Ⅰ)-propylene, K1 = 9.0, △H=-10.1 kcal/mole, △S =- 28.1cal/deg.mole. For Ni(Ⅱ)and ethylene, propylene and acetylene, the K1 values arc 2.8×10-1, 6.1× 10-3, 3.4×10-3, respectively, and for Zn(Ⅱ)and ethylene, propylene and acetylene are 3.0×10-3, 1.0×10-3 and 2.0×10-2, respectively. These data indicate that the stability of these complexes are of the following order: Ag(Ⅰ)>Ni(Ⅱ )>Zn( Ⅱ), which is also the order of the catalytic activities of the activated charcoal supported Ag(Ⅰ), Ni(Ⅱ) and Zn(Ⅱ) chlorides for the vapor phase hydrochlorination of acetylene.
