| 摘要: 采用气相色谱法,配合穆斯堡尔谱等其他手段研究了草酸铁与金属氯化物在氢气氛和氦气氛中的固相反应。实验结果表明,草酸高铁与氯化铜在180℃时发生氧化还原反应,与氯化亚锡在室温下发生固相还原反应,与碱金属氯化物不反应,但氯离子的存在明显提高了α—草酸亚铁的热稳定性且与氯化物中金属阳离子的价态有关,价态越高,作用越明显。 |

| Abstract: By use of non-isothermal technique in hydrogen and helium atmos-phere the solid state reactions of iron(Ⅲ)oxalate and metal chloride
salts was studied by gas chromatography accompanied by IR, XRD and Mössbauer spectroscopy, the results show that the solid state reaction of iron(Ⅲ) oxalate and tin(Ⅱ)chloride occurs at room temperature ,forming α-FeC2O4 and that the solid state reaction of iron oxalate and copper chloride starts at 180℃, releasing CO2 and forming Fe(OH)3.No reactioa is occured between iron oxalate and alkali chloride while the presence of chloride ion postpones the thermal decomposition of α-FeC2O4 in the following sequence MCI2. |
