| Abstract: | Predispersed solvent extraction (PDSE) of succinic acid with Tri-n-octylamine (TOA) dissolved in 1-octanol from aqueous solutions
of 50 g/L succinic acid was examined. It was found that the equilibrium data in PDSE was equal to that in conventional solvent
extraction in spite of the lack of mechanical mixing in PDSE. The influence of salts on succinic acid extraction and the stability
of colloidal liquid aphrons (CLAs) were also investigated. Results indicated that in the presence of sodium chloride, less
succinic acid was extracted by CLAs and the stability of CLAs decreased. However, the stability of CLAs was sufficient to
make PDSE practically applicable to real fermentation broth, considering the concentration range of salts in the fermentation
process for succinic acid. |
