Using XRY-1C calorimeter, the standard molar enthalpy of taurine was determined to be −2546.2 kJ mol . The reliability of the instrument used was tested by using naphthalene as reference material; and through comparing the molar combustion enthalpy of naphthalene measured with its standard value found in literature, the absolute error and relative error were found to be 4.53 kJ mol and 0.09%, respectively. The melting point and melting enthalpy of taurine were determined by Differential Scanning Calorimetry (DSC), which was found to be 588.45 K and −22.197 kJ mol, respectively. Moreover, using the DSC method, the specific heat capacities C of taurine was measured and the relationship between C and temperature was established. The thermodynamic basic data obtained are available for the exploiting new synthesis method, engineering design and industry production of taurine.
