Combinations of natural and synthetic inclusion compounds and their thermal stability

Abstract

Inclusion compounds do not belong to the group of simple compounds. They consist of molecules of the host and guest components. Some of them form supermolecules and exhibit supermolecular properties.Combinations of inclusion compounds as even more complicated systems need more methods to be used for their identification. Thermoanalytical study enables to study the sorption during their formation and the progressive liberation of their individual components and parts. Many layered silicates, phosphates and other similar synthetic and natural compounds enclosing or adsorbing eyclodextrins, pharmaceuticals, aromatics, various agroehemieals and inorganics are analysed from the view of their formation and properties.

About the thermal decomposition of tetracyanocomplexes

“…In [2,[29][30][31]] the thermal stabilities of new inclusion compound combinations are dealt with. Morphological studies showed a changed situation after the formation of the new products prepared from clinoptilolite (CT) zeolites.…”

Tunable clathrates

“…Thermal gravimetry, TG, and differential scanning calorimetry, DSC were employed to analyse the stoichiometries and thermal stabilities of all five inclusion compounds. 9,10 The compound H•A•3B was difficult to isolate, because when the guest liquid mixture is in the mole fraction range X B 0.5-1.0, the host shows a strong propensity for the formation of H•2A•2B.…”
