| 摘要: 本文以气相色谱为主配合红外光谱、差热热重和X衍射等手段研究了Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)水杨酸配合物的热稳定性。实验结果表明,这些化合物在He和H2中的热分解都经过三个过程:1.放出结晶水;2.放出Co2,分解为羧酸盐;3.放出CO2,产生呫(口辛)酮,最终分解为金属。实验表明Co(Ⅱ)、Ni(Ⅱ)配合物的分解产物对CO2加氢有催化剂作用。把以上实验与差热热重实验对照取得了更为园满的结果。 |

| Abstract: This paper reports the study on the thermal stability of Co(Ⅱ), Ni(Ⅱ) andCu(Ⅱ) salicylates by gas chromatography. Experimental results showed that the thermal decomposition of all these compounds generally went through the Jollowing three steps.(1) release of water of crystallization;(2) release of CO2 with the formation of carboxylate;(3) release of CO2 with the formation of xanthone and metal as the end product.Experimental results also showed that decomposition products of Co(Ⅱ), Ni(Ⅱ) coordination compounds exerted a catalytic effect on the hydrogenat-ion of CO2. From the variety of information that could be obtained by gas chromatography as a means to study the thermal stability of coordination compounds, its superiority over DTA and TG is evident. |
