Abstract
Polynuclear compounds dissolved and contained within an organic solvent are separated from the organic solvent by rendering the organic compounds insoluble within the organic solvent. Accordingly this invention removes polynuclear compounds from a saturated organic solvent. The polynuclear compounds are derived from black liquor obtained from kraft digestion. Whereby polynuclear compounds, substantially free of an organic solvent, are obtained from the organic solvent.
Claims9
A method to derive polynuclear compounds dissolved in an organic solvent, which comprises:
- providing an organic solvent containing dissolved polynuclear compounds, and
- separating said polynuclear compounds from said organic solvent, and
- recycling the heretofore separated organic solvent, whereby polynuclear compounds substantially free of an organic solvent, are obtained from an organic solvent.
