Abstract
The combustion enthalpy of glyphosate was determined by XRY-1C oxygen-bomb calorimeter at a constant volume. The standard mole combustion enthalpy and the standard mole formation enthalpy have been calculated to be −1702.19 and −1478.36 kJ mol−1, respectively. For testing the reliability of instrument, glycine and naphthalene were used as reference materials by comparing the measured values with the literature values, the absolute error and relative error are 2.58 kJ mol−1 and 0.26 % for glycine, respectively, and these of naphthalene are 4.08 kJ mol−1 and 0.08 %, respectively. Moreover, the constant-pressure heat capacities c p of glyphosate were measured by differential scanning calorimetry in the temperature range 303.15–365.15 K, and the relationship between c p and temperature was established. These related studies can provide a thermodynamic basis for their further application.
