DL-丙氨酸与醋酸铜固相配位反应的热化学研究

Studies on thermochemistry of solid state coordination reaction of DL-Alanine with cupric acetate

用自行研制的具有恒定温度环境的反应热量计,以4 m ol·L- 1 HCl溶液为量热溶剂,测得DL-丙氨酸与醋酸铜固相配位反应焓ΔrHm = 50.852 kJ·m ol- 1,从而计算了配合物trans-Cu(DL-Ala)2 的标准生成焓ΔfΗm = - 1 015.419 kJ·m ol- 1.

The reaction enthalpy of solid solid coordination reaction of DL Ala with cupric acetate is determined by solution calorimetry in an isoperibel reaction calorimeter. The calorimetric solvent is the solution of hydrochloric acid (4 mol·L -1 ) . According to the results, the values: Δ rH m =50.858 kJ·mol -1 , Δ rH m (trans Cu(DL Ala) 2,s)=-1 015.413 kJ·mol -1 are recommended.
