Phase transitions in solid cis-1,2-cyclohexanediol and trans-1,2-cyclo
hexanediol and cis/trans-1,4-cyclohexanediol have been studied by diff
erential scanning calorimetry over the temperature range 241 to 383 K.
Besides a low-temperature crystalline form, DSC curves show the exist
ence of a solid rotator phase in cis-1,2-cyclohexanediol whilst for th
e others, only one solid phase is present. Enthalpies of sublimation a
nd vaporization were determined by evaporation into a vacuum using an
isothermal calorimeter.
