| Abstract: | The extraction of acetic acid from aqueous solutions by tri-n-octylamine dissolved in various diluents in wide range of amine concentration (0.23 -1.15 mol/ L) is studied. Extraction equilibria of acetic acid in the solution of tri -n-octylamine in five various solvents at 298.15 K is measured. Diluting solvents used in this study are hexane, cyclohexane, toluene, methyl isobutyl ketone (MIBK), and propanol. Using Bizek approach two acids : amine complexes. (Acid), (Amine) and (Acid) , (Amine)2 is are assumed to exist in the organic phase in the case of proton- donating diluents, while the complexes (Acid), (Amine) and (Acid)2, (Amine)3 are suggested in the case of non-proton-donating diluents. As a result of batch extraction experiments, distribution coefficients (D), loading factors (Z), and overall extraction constants (K11, K12 , K23) are calculated. |
