Herein, since the extraction of organic acids is very important for recovery, acrylic acid was investigated from aqueous solutions by different diluents of trioctylamine (TOA). The extraction of acrylic acid with TOA dissolved in various individual solvents has been worked. Solvents have selected as dimethyl phthalate (DMP), cyclohexyleacetate (CHA), methyl isobutyl ketone, 2-octanone, 1-octanol, and 1-decanol. The experimental results of experiments are reported as distribution coefficients, D, loading factors, Z, and extraction efficiency, E. It is essential to improve extraction by adding extractant. The maximum removal of acrylic acid is 97.32% with DMP 1.15 mol/kg initial concentration of TOA. Here in, the LSER model has been applied to TOA + alcohol systems on extraction of acrylic acid to make predictions of distribution coefficient.
