Reactive extraction of propionic acid using Aliquat 336 in MIBK: Linear solvation energy relationship (LSER) modeling and kinetics study

摘要

This study presents linear solvation energy relationship (LSER) modeling of reactive extraction of propionic acid using Aliquat 336 in MIBK as diluent. Reaction was slow in Aliquat 336 + MIBK with rate constant at 0.0079 (m~3/kmol)~(0.55) s~(-1). Order of reaction with respect to acid and Aliquat 336 was 1 and 0.9 respectively. Modeling of reactive extraction equilibria using LSER was carried out and predicted a close resemblance of experimental data.
