Solvent Extraction and Association of Nitrophenols with Trioctylphosphine Oxide in Cyclohexane

Extraction of phenol and nitrophenols into cyclohexane and association of these phenols with trioctylphosphine oxide (TOPO) in the organic phase were investigated at 298 K. A linear relation was found between the logarithm of the partition coefficient of the phenols and the logarithm of their associ...

Summary:Extraction of phenol and nitrophenols into cyclohexane and association of these phenols with trioctylphosphine oxide (TOPO) in the organic phase were investigated at 298 K. A linear relation was found between the logarithm of the partition coefficient of the phenols and the logarithm of their association constant with TOPO.
