摘要：
Protonation of diazacrown ethers and cryptands in water was studied using potentiometric and calorimetric titrations. The potentimetric titrations were performed in two different ways. Calculated stability constants from both titrations were in good agreement with each other. Values of stability constants and reaction enthalpies give further insight into the structures of the mono- and bisprotonated ligands in solution.
