Surface| Zusammenfassung: | The identity of “β-cyclodextrin - benzene carboxylic acid” complexes synthesized in aqueous solutions and on the surface of highly dispersed silica was established. It was proved that obtained complexes are inclusion compounds of the "host - guest” type with equimolar ratio 1:1. The stability constants of inclusion complexes and the standard thermodynamic parameters of their formation were calculated. From the results of quantum-chemical calculations it was made a conclusion about equal probability of “tail forward” and “head forward” inclusion complexes formation. The peculiarities of dehydration and thermal destruction of the inclusion complexes in comparison with individual compounds and their equimolar mixtures were revealed. |
