Extraction of phenols with tert-amyl methyl ether from coking plant wastewater

Abstract

The equilibrium distribution coefficient K for mixed phenols, between coking plant wastewater and tert-amyl methyl ether (TAME), is determined. The effect of pH upon the distribution K of pure phenol is measured in the buffered water solution-phenol-TAME system. Laboratory and pilot plant results of continuous countercurrent extraction of mixed phenols from coking plant wastewater are reported.
