使用RD-Ⅰ型热导式自动量热计测量N-(对位取代苯基)氨基乙酸的加质子热及其与Cu(Ⅱ)生成配合物的生成热,首次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如下的直线焓关系式:△H_(ML)=Q—β△H_(HL),式中:△H_(ML)为配合热,△H_(HL)为加质子热,Q和β为常数。
The proton heat of N- (para-substituted phenyl) glycine and the formation heat of its complex with Cu (Ⅱ) were measured by RD-Ⅰ thermal conductivity automatic calorimeter. The enthalpy relationship between the heat of formation and the proton heat of ligand is as follows: △ H ML ML = Q - β △ H HL, where ΔH ML is the heat of association , △ H_ (HL) plus proton heat, Q and β are constant.
