Kinetic deuterium isotopic effects in the thermal decomposition of β-cyclodextrin hydrates

The apparent kinetic parameters of the thermal decomposition of the beta-cyclodextrin-heavy water complex were obtained from dynamic TG analysis. Various calculation methods were used and the results compared with those of the ordinary water complex. The processes of decomposition occur as zero order reactions with an activation energy of 65.7 and 69.7 kJ/mole respectively, calculated for one mole of water and heavy water. The parameters were used to estimate the kinetic deuterium isotopic effect.
