Abstract:The phase transitions of 2-methoxycinnamic acid, 3-methoxycinnamic acid, 4-methoxycinnamic acid and 4-hydroxy-3-methoxycinnamic acid were studied by DSC. The thermodynamic parameters of phase transitions for these compounds are reported in this paper. In addition, the ~1H-NMR spectra of compounds 2-methoxycinnamic acid, 3-methoxycinnamic acid and 4-methoxycinnamic acid have been measured, and the change of β-H chemical shifts is consitent with that of DSC data fOr these compounds.
Keywords:Cinnamic acid derivative  DSC(Differential Scanning Calorimetry)  Ferulic acid  Enthalpy of fusion
