摘要
The reactions between sodium iodide, potassium iodide and a series of N-(parasubstituted phenyl) nitrogen-hetero-15-crown-5 were studied by titration calorimetry at 25 ℃ in ethanol. It was found that the aza-crown ethers and the alkali metal ions form 1:1complexes. The electron-donating substituent on the phenyl ring may enhance the ligation ability of the macrocyclic ligand. It was found that linear thermodynamic function relationships exist in the systems studied.
