Studies of the Extraction of Phenol by N-Octanoylpyrrolidine

The behavior of phenol of wastewater extraction by N-octanoylpyrrolidme (OPOD) in kerosene was studied. The dependence of the extraction distribution ratios on the concentrations of extractant, phenol, acidity and temperature was investigated. By means of the slope method, the composition of the extracted complex was deduced to be C6H5. OPOD, and the related thermodynamic functions were also calculated. The IR and NMR spectra showed the presence of intermolecular hydrogen bonding between phenol and OPOD. The experimental results indicated that OPOD could extract phenol effectively.
