Abstract
Protonation of diazacrown ethers and cryptands in water was studied us ing potentiometric and calorimetric titrations. The potentimetric titr ations were performed in two different ways. Calculated stability cons tants from both titrations were in good agreement with each other. Val ues of stability constants and reaction enthalpies give further insigh t into the structures of the mono- and bisprotonated ligands in soluti on.
