ABSTRACT

The heat capacities of b-D-(-)-arabinose were measured using a Quantum Design Physical Property Measurement System (PPMS) over the temperature range from (1.9 to 300) K, and the experimental values were fitted as a function of temperature using a series of theoretical and empirical models in the appropriate temperature ranges, from which the corresponding thermodynamic functions were calculated. The standard molar heat capacity, entropy and enthalpy of b-D-(-)-arabinose at T = 298.15 K and P = 0.1 MPa were determined to be Cop ;m = (186.29 +- 1.86) J K 1 mol 1, So m = (181.72 +- 1.83) J K 1 mol 1 and Ho m = (28.52 +- 0.29) kJ mol 1, respectively.
