【摘要】本文用红外、紫外可见漫反射、X 射线粉末衍射和四极质谱等实验手段,研究了四氰合镍酸钾一水合物与草酸、丙二酸、反丁烯二酸、丁二酸、己二酸的固相反应,发现 K₂[Ni（CN）₄]·H₂O 与一些固体酸在室温下就发生反应,生成 Ni（CN）₂·xH₂O,并放出 HCN 气体.由产物与反应物相对含量大小,得到固体有机酸的酸性强弱顺序为:草酸二水合物>丙二酸>反丁烯二酸>丁二酸>己二酸。讨论了可能的反应机制.更多还原

【Abstract】 In this paper,the solid state reactions between potassium tetracyanonickelate（Ⅱ）and oxalic,malonic,fumaric,succinic,adipio acid are studied,followed by moderntechniques such as IR,DRS,XRD and MS.It is found that the reactions occur at roomtemperature.Ni（CN）₂·xH₂O is obtained as a main product and HCN gas is detected.The acidity of these solid organic acids decreases in the order:oxalic>malonic>fumaric>succtnic>adipic acid.Proton is believed to play an important role in thereaction process.And the possible mechanism is discussed.更多还原
