摘要
用新型的具有恒定温度环境的反应热量计，以一定比例的ＤＭＳＯ与ＤＭＦ混合溶液作为量热溶剂，分别测定了反应物和产物的溶解焓．设计了一个新的热化学循环，得到固相配位反应的反应焓＝２２４．４５３ｋＪ·ｍｏｌ－１，计算出了配合物Ｃｏ（ＳＡＯ）２·２Ｈ２Ｏ的标准生成焓＝－９５７．２０５ｋＪ·ｍｏｌ－１。
The reaction enthalpy of solid-solid coordination reaction of salicy-laldoxime with cobalt acetate is determined by solution calorimetry in a new model isoperibel reaction calorimeter. The calorimetric solvent is a mixed solution consisting of DMSO and DMF,a new thermochemical cycle is designed to determine the standard enthalpy of formation for Co(SAO)2· 2H2O. According to the results obtained,the value = 224. 453 kJ. mol-1[Co(SAO)2· 2H2O,s ] =- 957. 205 kJ· mol-1are recommended.
