摘要: Abstract The reaction kinetics of the esterification acetic acid with ethanol, catalyzed both homogeneously by acid, and heterogeneously Amberlyst 15, have been investigated. reactions were carried out at several temperatures between 303.15 353.15 K various starting reactant compositions. Homogeneous heterogeneous described using models proposed Popken et al. [T. Popken, L. Gotze, J. Gmehling, Reaction chemical equilibrium homogenously methanol methyl acetate hydrolysis, Ind. Eng. Chem. Res. 39 (2000) 2601–2611]. These use activities instead mole fractions. Activity coefficients calculated ASOG [K. Kojima, K.
