| 摘 要： | 在常温常压下，用Ｎａ２Ｓ２Ｏ３／Ｆｅ－Ｍｎ粉为联合活化剂，将一氧化碳通入ＣｏＣｌ２／ＣＨ３ＯＨ溶液，制备了Ｎａ［Ｃｏ－（ＣＯ）４］，３ｈ后转化率可达９０％以上。选择性接近１００％。ＩＲ分析发现产物溶液在１９０４ｃｍ－１左右有一强的特征吸收峰，证实了［Ｃｏ（ＣＯ）４］－离子的存在。研究了反应条件对产率的影响，讨论了合成羰基钴钠的反应机理。

| Abstract: | Synthesis of sodium tetracarbonylcobaltate was studied using CoCl2/Na2S2O3/Fe-Mn system under carbon monoxide atmosphere and room temperature. The conversion of Co2+ to NaCotCO)4] is over 90% after 3h, the selectivity is about 100%. The amount of reagent and the reaction conditions have been found to have major effect on the formation of Na Co (CO)4]. IR study of the products shows that there is a very strong band at 1904cm-1 indicating the formation of sodium tetracarbonylcobaltate in the reaction. |
