Synthetic Route of 14098-44-3. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 14098-44-3, Name is Benzo-15-crown-5. In a document type is Article, introducing its new discovery.
The determination of stability constants and thermodynamic values for the reaction of crown ethers with alkali-, alkaline-earth ions, and the silver ion was achieved by calorimetric titration in methanol.Through modification of the experimental conditions it is possible to measure separately the formation of 1:1- and 2:1-complexes (ratio of ligand to cation).With the exception of Ag+ and Ca2+ all ions examined form both kinds of complexes with the various 15 C 5 ligands.The complex stabilities are influenced by enthalpic and entropic contributions. 18 C 6 and DC 18 C 6, having a bigger diameter than 15 C 5, show a definite increase of the stability of 1:1-complexes.Only the Cs+ ion with the largest radius forms 2:1-complexes.A good agreement is found with values determined potentiometrically for the 1:1- and 2:1-complex formation of Na+.
