Certain mixtures of cyclodextrin derivatives, which were synthesized in mildly basic conditions, can be separated into mixtures that crystallize easily and mixtures of similar composition, which remain amorphous. Thus, it is possible to obtain the particular advantages of crystalline and/or amorphous state components from one reaction product. Both crystalline and amorphous components of the product have good ability to form inclusion complexes.
Selon l'invention, certains mélanges de dérivés de cyclodextrine, qui ont été synthétisés dans des conditions légèrement basiques, peuvent être séparés en mélanges qui cristallisent facilement et en mélanges de composition semblable qui restent amorphes. Il est ainsi possible d'obtenir les avantages particuliers de composants à l'état cristallin et/ou amorphe à partir d'un produit de réaction. Tant les composants cristallins que les composants amorphes du produit présentent une bonne capacité à former des complexes d'inclusion.
