用微热量仪对配合物[Mn(SCZ)3](PA)2.H2O在溶剂N,N-二甲基甲酰胺(DMF)中不同浓度(b)时的溶解焓进行了测定,用计算机拟合的方法求得该配合物的标准摩尔溶解焓(Δd issHmθ=-43.607 kJ.mol-1)及溶解焓(Δd issH)的经验公式(Δd issH=-43.607-454.98b+9378.2b1/2)。由此得到配合物的相对表观摩尔焓(ΦLi)、相对偏摩尔焓(Li)以及配合物的稀释焓(Δd ilH1,2)的经验公式:ΦLi=-454.98b+9378.2b1/2,Li=-909.96b+14067.3b1/2和Δd ilH1,2=-454.98(b12/2-b11/2)+9378.2(b2-b1)。
The enthalpies of enthalpies for the complex [Mn (SCZ) 3] (PA) 2.H2O at different concentrations (b) in DMF and DMF were measured by microcalorimetry. The empirical formula (Δd issH = -43.607-454.98b + 9378.2b1 / 2) of the standard molar enthalpy of solution (Δd issHmθ = -43.607 kJ · mol-1) and the enthalpy of solution (Δd issH) ). The empirical formula of relative apparent molar enthalpy (ΦLi), relative partial molar enthalpy (Li) and the enthalpy of dilution (Δd ilH1,2) of the complex was obtained: ΦLi = -454.98b + 9378.2b1 / 2, Li = -909.96b + 14067.3b1 / 2 and Δd ilH1,2 = -454.98 (b12 / 2-b11 / 2) +9378.2 (b2-b1).
