The heat capacity, C-p, of glycerol was measured between 298 and 383 K with a DSC and a modulated scanning calorimeter operating at 5 mHz. The two sets of data show an excellent agreement and can be fitted to the equation : C-p (J mol(-1) K-1)=90.983+0.4335T. The C-p values, at 298.15 K, tabulated in literature and in data handbooks agree with the current data, but the equation reported for C-p(T) at higher temperatures is wrong, giving a slope which is ca. 60% of the determined value.
