使用RD-1型热导式自动量热计测定了N-(间位取代苯基)氨基乙酸(m-RPhG)酸根的加质子热及其与Cu(Ⅱ)生成配合物的生成热。用量热法从实验上验证了配合物的生成热与配位体的加质子热之间存在着如下的直线焓关系式:△H_M=Q-β△H_L。式中△H_M为配合物的生成热。△H_L为配位体的加质子热,Q和β为常数。还计算了配合物的生成熵和配位体的加质子熵,结果表明配合物的生成熵与配位体的加质子熵之间也存在线性关系。
The proton heat of the N- (meta-substituted phenyl) glycine (m-RPhG) acid radical and the formation heat of its complex with Cu (Ⅱ) were measured by the RD-1 thermal conductivity automatic calorimeter. The experimental results show that there is a linear enthalpy relation between the formation heat of the complex and the proton heat plus the following proton heat: △ H_M = Q-β △ H_L. △ H_M where the complex heat of formation. △ H_L is the ligand plus proton heat, Q and β are constants. The entropy of the complex and the proton entropy of the ligand were also calculated. The results show that there is a linear relationship between the entropy of the complex and the proton entropy of the ligand.
