Saturation molar heat capacities C-sat in the liquid phase of five 1-alkanols from C-10 to C-20 were measured by a commercial SETARAM heat conduction calorimeter. Results obtained cover the following temperature range: 1-decanol 304-405 K, 1-dodecanol 307-358 K, 1-hexadecanol 328-387 K, 1-octadecanol 338-397 K, and 1-eicosanol 347-517 K. The heat capacity data obtained in this work were merged with available experimental data from literature, critically assessed and sets of recommended data were developed by correlating selected data as a function of temperature.
