Abstract

The stability of the β-CD cinnamic aldehyde inclusion complex wasinvestigated by TG and DSC. The weight loss takes place in three stages:dehydration occurs at 50–120 °C; the dissociationof β-CD⋅C9H8O occurs at 200–260 °C;and the decomposition of β-CD begins at 280 °C. Thekinetics of the dissociation of cinnamic aldehyde from the β-CD cavitywere studied by means of thermogravimetry both at constant temperatureand linear increasing temperature. The results show that the dissociationof β-CD⋅C9H8O is dominated by a one-dimensional diffusionprocess. The activation energy, E, is 160 kJ⋅mol-1. Thepre-exponential factor A is 5.8 × 1014 min-1.
