Etude thermodynamique de la reaction d'hydratation de la beta-cyclodextrine - Claudy, P.; Germain, P.; Letoffe, J.M.; Bayol, A.; Gonzalez, B. (Elsevier)
Le comportement thermique de la β-cyclodextrine a ete etudie de -150 a + 300^oC par thermogravimetrie et analyse calorimetrique differentielle. L'hydrate stable a temperature ambiante est le undecahydrate. Sa deshydratation s'effectue en deux etapes correspondant au depart de 7 et 4 molecules d'eau. L'enthalpie d'hydratation et la solubilite a 25^oC ont ete determinees par calorimetrie de dissolution. | The thermal behaviour of β-cyclodextrin has been studied in the temperature range -150 to + 300 ^oC by TG and DSC measurements. At room temperature, the stable hydrate contains 11 molecules of water. Dehydration occurs in two steps corresponding to the loss of 7 and 4 molecules of water. The enthalpy of hydration and solubility at 25 ^o C have been determined by dissolution calorimetry.
