Resumo(s)
This paper reports experimental and modeling work
concerning alcoholysis reactions between butanol and
ethyl butanoate, catalyzed by Lipozymee in n-hexane,
using a batch stirred system at 608C. Description of the
reaction kinetics was based on a postulated multisubstrate
Ping Pong Bi Bi mechanism, and appropriate
rate expressions were derived for all components in the
reaction medium. Simplified models were fitted by nonlinear
multiresponse regression analysis to data (experimental
or calculated from mass balances, as appropriate)
encompassing the concentrations of free butanol, ethyl
butanoate, ethanol and butyl butanoate. Finally, incremental
F-tests were performed to assess the simplest
model form that was able to provide a statistically good
fit throughout the entire reaction time frame.
