Abstract

The esterification of 1,4-butanediol with acrylic acid catalyzed by sulfuric acid in the absence of solvent was studied in a batch stirred reactor. Experiments were carried out with different acid/ alcohol mole ratios and different amounts of sulfuric acid in the temperature range 70 to 90°C and 1 atm. It was found that the esterification of 1,4-butanediol with acrylic acid is a two-step consecutive, reversible reaction and each esterification step follows a first-order rate expression with respect to each component. A kinetic model was proposed to describe such a consecutive, reversible esterification reaction catalyzed by sulfuric acid. The equilibrium constants were determined from the equilibrium concentrations of each component while the rate constants in each reaction step were calculated by correlating the experimental data with the developed kinetic model.
