Thermodynamic properties of l-threonine

Abstract

Standard molar enthalpy of formation in the solid state at T=298.15K 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 5K to 370K. The entropy of formation and Gibbs energy of formation at T=298.15K 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.
