【Abstract】 Fe₂（SO₄）₃·7H₂O was employed to catalize esterifications of some substituted acetic acids with ethanol. Activation energies of these reactions have been measured.It was found that there was a linear relationship between σ^*, E_s and activation energy. E_a: E_a=-2.303RTσ^*p^M-2.303RTbE_s+E₀ where p^M is the reaction constant; E₀ is the activation energy of the reaction between acetic acid and ethanol; and the coefficient b is 2.2.更多还原
