Özet
Extractability of oxoethanoic acid (glyoxylic acid (GA)) from aqueous solutions, with N-methyl-N,N-dioctyloctan-1-ammonium chloride (Aliquat 336 (A336)) in various diluents, including isoamyl alcohol, octan-1-ol, nonan-1-ol, decan-1-ol, methyl ethyl ketone (MEK), diisobuthyl ketone (DIBK), hexan-2-one, toluene, kerosene, and n-hexane has been investigated. Batch extraction results were calculated and reported as distribution coefficients (K-D), loading factors (Z), and extraction efficiency (E) at T = 298 K. These solvents with using A336 is more effective than a single solvent (K-D >> 1). Hexan-2-one has been found to be the most effective diluent with the highest value of K-D (17.37) at 1.31 mol.kg(-1) concentration of A336. The results of the liquid liquid equilibrium measurements were correlated by a linear solvation energy relationship (LSER) model which takes into account physical interactions and Freundlich and Langmuir equations. Experimental results of the oxoethanoic acid extraction are compared to model results.
