ABSTRACT

Standard molar enthalpy of formation in the solid state at T = 298.15 K of L-threonine was derived from energy of combustion determined by static bomb combustion calorimetry. Heat capacity of L-threonine was measured by vacuum adiabatic calorimetry over the temperature range (7.37 371.97) K. Heat capacities and main thermodynamic functions in solid state were tabulated as a function of temperature from 5 K to 370 K. The entropy of formation and Gibbs energy of formation at T = 298.15 K of L-threonine in the condensed state were computed on the basis of the experimental results obtained. All results are compared with experimental values reported in the literature.
