Abate, E. Badea, I. Blanco, D. D'Angelo, G. Della Gatta] Molar heat capacities of twelve linear alkane-α,ω-diamides H2NOC-(CH2)(n-2)-CONH2, (n=2 to 12 and n=14) were measured by differential scanning calorimetry at T=183 to 323 K. Heat flow rate calibration of the Mettler DSC 30 calorimeter was carried out by using benzoic acid as reference material. The calibration was checked by determining the molar heat capacity of urea in the same temperature range as that of measurements. The molar heat capacities of alkane-α,ω-diamides increased in function of temperature and fitted into linear equations. Smoothed values of C p,m at 298.15 K displayed a linear increase with the number of carbon atoms. The C p,m contribution of CH2 group was (22.6±0.4) J K−1 mol−1, in agreement with our previous results concerning linear alkane-a,ω-diols and primary alkylamides as well as the literature data on various series of linear alkyl compounds.
