ORJUELA LONDONO, Álvaro et al. A study of butyl acetate synthesis: 4- reaction kinetics. Ing. Investig. [online]. 2006, vol.26, n.2, pp.28-36. ISSN 0120-5609.

This work was aimed at studying liquid-phase acetic acid and butyl alcohol esterification reaction (P_atm=0.76 Bar), using an ion exchange resin (Lewatit K-2431) as catalyst. The effect of the absence of internal and external mass transport on catalyst particles was established in the research conditions used here. A set of assays to determine the effect of catalyst load (0.5%, 1%, 2% w/w) temperature (73°C, 80°C, 87°C) and molar ratio (1:2, 1:1, 2:1 acid/alcohol) on reaction rate was carried out and both LHHW and pseudo-homogeneous kinetic expressions were obtained, these being in good agreement with the experimental data.

Keywords : ion exchange resins; esterification; butyl acetate; kinetics.
