| 摘要: 用溶解量热法,以一定比例的盐酸(0.2mol·L-1)与无水乙醇的混合溶液作为量热溶剂,用新型的具有恒定温度环境的反应热量计,于298.15K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,得到了两步固相反应的反应焓,并计算出了Cd(OAc)(OAB)·2H2O和Cd(OAB)2的标准生成焓。 |

| Abstract: The solid-solid state coordination reaction enthalpy of cadmium acetate with o-aminobenzoic acid by two steps has been determined by solution calorimetry in an isoperibel reaction calorimeter at 298.15K.The calorimetric solvent is a mixed solution consisting of HCl(0.2mol·L-1 ) and ethyl alcohol.Anew thermochemical cycle is designed, and the standard enthalpy of formation for Cd(OAc) (OAB)·2H2Oand Cd(OAB)2 are determined.The recommended values of standard enthalpy of formation are △fHmΘ[Cd(OAc)(OAB)·2H2O, s] = -1584.071 kJ·mol-1 and △fHmΘ[Cd(OAB)2, s] = -911.803kJ·mol-1. |
