Isobaric heat capacities C-p in the liquid phase of seven isomeric C-5 alkanols and in the solid phase for 2,2-dimethyl-1-propanol were measured by a commercial SETARAM heat conduction calorimeter. Results obtained cover the following temperature range: 2-methyl-1-butanol (CAS-RN 137-32-6) 308-338K, 2-methyl-2-butanol (75-85-4) 308-348K, 3-methyl-1-butanol (123-51-3) 308-357 K, 3-methyl-2-butanol (598-75-4) 304-347 K, 2-pentanol (6032-29-7) 308-367 K, 3-pentanol (584-02-1) 308-368 K, 2,2-dimethyl-1-propanol (75-84-3) 310-363 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.
