Effect of Diluent Polarity on Extraction Equilibria of Acrylic Acid from its Aqueous Solutions by Tri-n-Octylaime

Abstract:

Acrylic acid and its derivatives are raw materials for polymeric, paint additives, adhesive, textile and leather treating products. The increasing demand of acrylic acid is great attention for its recovery from dilute aqueous solutions. With this aim, the amine based extraction of acrylic acid from its aqueous solutions in polar diluents was investigated. In the extraction, the tri-n-octylamine in polar diluents was found to provide higher extraction efficiency than that in nonpolar diluents. It was presumed that the acid-amine complex formation is difficult and the low solubility of acid-amine complex is low in nonpolar diluents. Higher extraction efficiency for acrylic acid was obtained with the polarity of active diluents due to higher solubility for acid-amine complex with polarity of diluents.
