Mungma, Nuttakul published the artcileReactive extraction of lactic acid, formic acid and acetic acid from aqueous solutions with tri-n-octylamine/1-octanol/n-undecane, Name: n-Octanol, the main research area is lactic formic acetic acid aqueous solution extraction fermentation broth.
The present work develops the basics for the isolation of lactic acid, acetic acid and formic acid from a single as well as a mixed feed stream, as is present, for example, in fermentation broth for lactic acid production Modeling of the phase equilibrium data is performed using the law of mass action and shows that the acids are extracted according to their pka value, where formic acid is preferably extracted in comparison to lactic and acetic acid. Back-extraction was performed by 1 M NaHCO3 solution and shows the same tendency regarding the pka value. Based on lactic acid, the solvent phase composition, consisting of tri-n-octylamine/1-octanol/n-undecane, was optimized in terms of the distribution coefficient The data clearly indicate that, compared to phys. extraction, mass transfer can be massively enhanced by reactive extraction With increasing tri-n-octylamine and 1-octanol concentration, the equilibrium constant increases. However, even when mass transfer increases, tri-n-octylamine concentrations above 40 wt%, lead to third phase formation, which needs to be prevented for tech. application. The presented data are the basis for the transfer to liquid membrane permeation, which enables the handling of emulsion tending systems.
