The present study based on the succinic acid recovery from its aqueous solution using reactive extraction. Tri-n-octyl amine (TOA), a tertiary amine used as extractant along with three different active diluents like Benzyl alcohol, 2-octanol, and 1-decanol. The effect of diluent on the extraction efficiency, distribution coefficient, loading factor, and equilibrium complexation were investigated using these three diluents.
