Abstract (en)

[origin: WO0136490A2] 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.
