ABSTRACT:
The present invention relates to a process for the solvent extraction of polychlorinated organic compounds from porous materials. Specifically, the present invention describes a process for the use of a solvent extraction of polychlorinated organic compounds, such as hexachloroethane, hexachlorobutadiene and hexachlorobenzene from porous materials, such as a vinyl ester resin. When the level of hexachlorinated organic compounds is reduced to a level of 7 ppm or below, the porous material may be disposed of in an environmentally acceptable manner such as by incineration or by landfill.
