摘要：
A PROCESS IS DESCRIBED FOR SEPARATING AND RECOVERING COMPLEXIBLE LIQUIDS FROM FEEDSTREAMS CONTAINING THEM, COMPRISING THE STEPS OF COMPLEXING THE LIGANDS WITH A COMPLEXING SOLUTION, STRIPPING IMPURTIES OUT OF SOLUTION, DECOMPLEXING BY FLASHING AT PRESSURES OF FROM 1 ATMOSPHERE TO ABOUT 40 ATMOSPHERES, RECYCLING SOLVENT TO THE
COMPLEXER AND THEREAFTER RECOVERING SAID LIGANDS AS A HIGH PURITY PRODUCT. THE COMPLEXING SOLUTION COMPRISES GROUP I-B METAL SALTS DISSOLVED IN LOW VOLATILITY AROMATIC SOLVENTS. THE LIGANDS ARE DECOMPLEXED BY EITHER FLASHING OFF A HIGH PRESSURES OR BY MULTIPLE STAGE FLASHING.
