What is Evaporation of the fragrance component, cinnamyl alcohol, using simultaneous TG–DTA about?

The thermal behavior of cinnamyl alcohol, which is used in the perfume industry to create a sweet, balsamic and hyacinth-like fragrance, was examined with a simultaneous thermogravimetric-differential thermal analysis (TG-DTA) unit. The sample was subjected to a controlled rising temperature regime under a regulated purge gas flow rate. The evaporation rates and coefficient of evaporation were calculated from TG-DTG data. From the DTG curve, it was found that the evaporation of cinnamyl alcohol is a zero-order process. The activation energy and enthalpy of vaporization for the evaporation process were determined by the use of the Arrhenius and Clausius-Clapeyron equations, respectively. The enthalpy value was calculated to be 68:10 AE 0:84 kJ, while the energy of activation was found to be 66:34 AE 0:84 kJ. The Langmuir equation was applied to the evaporation data, enabling the vapor pressure curves to be determined.
