Abstract
The heat capacity of maltitol has been measured with an adiabatic calorimeter for the crystal from 100 K to 425 K (T m = 420 K), for the glass from 249 K to T g (around 311 K) and for the liquid from T g to 400 K. The heat of melting is 55.068 kJ/mol. The calorimetric glass transition occurs at about T g = 311 K with a sudden jump of the heat capacity ΔC p (T g ) of about 243.6 J/(K mol). The excess entropy between the undercooled liquid and the crystal was calculated from the heat capacity data and was used to estimate the Kauzmann temperature T K which was found 50 K below T g . ΔC p (T g ) and T K for maltitol were compared to other compounds like sugars, polyol and hydrogen bonded liquids. It has been found that the glass former maltitol is a "fragile" liquid on the thermodynamic point of view.
