Abstract
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 (KD), loading factors (Z), and extraction efficiency (E) at T = 298 K. These solvents with using A336 is more effective than a single solvent (KD ≫ 1). Hexan-2-one has been found to be the most effective diluent with the highest value of KD (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 mo...
