Thermodynamic properties of organic oxygen compounds. Part XXVII. (±)-Butan-2-ol and (+)-butan-2-ol

Abstract

The heat capacities of (±)-butan-2-ol (crystals, glass, and liquid) and (+)-butan-2-ol (crystals and liquid) have been measured by adiabatic calorimetry at temperatures between 11 K and 350 K. Triple points and heats of fusion have been measured for both substances, and the glass transition temperature of (±)-butan-2-ol has been determined. Thermodynamic properties of the compounds have been calculated. The entropies in the ideal gas state have been compared with published values. (±)-Butan-2-ol probably forms a racemic solid solution.
