本文以穆斯堡尔谱为主要手段并配合气相色谱、红外光谱等手段研究了碱式Fe(Ⅲ)水杨酸配合物和Fe(Ⅱ)水杨酸配合物在H_2和He中的热稳定性。实验结果表明,Fe(Ⅲ)和Fe(Ⅱ)配合物的热分解都分三个阶段完成:(1)放出结晶水或脱去羟基水;(2)放出CO_2,形成新的羧酸盐,Fe(Ⅲ)逐渐被羧酸根还原成Fe(Ⅱ);(3)放出CO_2,产生呫(口辛)酮,最后生成铁的氧化物。在He中,Fe(Ⅲ)配合物分解产物对CO_2有加氢催化作用,最
In this paper, Mossbauer spectroscopy as the main means and with gas chromatography, infrared spectroscopy and other means to study the thermal stability of Fe (Ⅲ) salicylic acid complex and Fe (Ⅱ) salicylic acid complex in H_2 and He Sex. The experimental results show that the thermal decomposition of Fe (Ⅲ) and Fe (Ⅱ) complexes is completed in three stages: (1) release of water of crystallization or removal of hydroxyl water; (2) release of CO_2 to form new carboxylate, Fe (Ⅲ) is gradually reduced to Fe (Ⅱ) by carboxylate; (3) CO_2 is released to produce xanthones, and finally iron oxides are formed. In He, the decomposition products of Fe (Ⅲ) complexes have a catalytic effect on CO_2 hydrogenation
