Heat capacities of selected cycloalcohols

• Heat capacities of five alcohols were determined by Tian–Calvet calorimetry.
• Results were compared with selected estimation methods.
• Phase behaviour was explored by differential scanning calorimetry.
• Calorimetric measurements were complemented by FTIR spectroscopy.

Isobaric heat capacities of selected cycloalcohols (cyclobutanol, CAS RN: 2919-23-5; cyclopentanol, CAS RN: 96-41-3; cyclohexanol, CAS RN: 108-93-0; cycloheptanol, CAS RN: 502-41-0; cyclooctanol CAS RN: 696-71-9) were measured with a highly sensitive Tian–Calvet calorimeter in the temperature range from 254 K to 352 K. Experimental heat capacity data were correlated as a function of temperature. The phase behavior was investigated with a differential scanning calorimeter. Calorimetric measurements were complemented by FTIR spectroscopy for less volatile compounds (cyclohexanol, cycloheptanol, cyclooctanol). The main aim of this work was to fill the gap in reliable heat capacity data for these compounds and to extend the knowledge base required for a better understanding of alcohols self-association.
