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. 固相配位反应 热化学 醋酸钴 水杨醛肟 solid-solid state reaction thermochemistry cobalt acetate solicylaldoxime O641.4 1995-06-01 2021-04-01 6
