EXTRACTION OF NICKEL(0) COMPLEXES FROM NITRILE MIXTURES WITH REDUCED POWER FORMATION

EXTRACTION OF NICKEL(0) COMPLEXES FROM NITRILE MIXTURES WITH REDUCED POWER FORMATION

A PROCESS FOR EXTRACTIVELY REMOVING HOMOGENEOUSLY DISSOLVED CATALYSTS FROM A REACTION EFFLUENT OF A HYDROCYANATION OF UNSATURATED MONONITRILES TO DINITRILES, BY EXTRACTION BY MEANS OF A HYDROCARBON H, WHICH COMPRISES A) ADDING A NONPOLAR APROTIC LIQUID L TO THE REACTION EFFLUENT TO OBTAIN A STREAM I...

Zusammenfassung:A PROCESS FOR EXTRACTIVELY REMOVING HOMOGENEOUSLY DISSOLVED CATALYSTS FROM A REACTION EFFLUENT OF A HYDROCYANATION OF UNSATURATED MONONITRILES TO DINITRILES, BY EXTRACTION BY MEANS OF A HYDROCARBON H, WHICH COMPRISES A) ADDING A NONPOLAR APROTIC LIQUID L TO THE REACTION EFFLUENT TO OBTAIN A STREAM I, AND B) EXTRACTING THE STREAM I AT A TEMPERATURE T WITH THE HYDROCARBON H TO OBTAIN A STREAM II COMPRISING THE HYDROCARBON H ENRICHED WITH THE CATALYST AND A STREAM III HAVING A LOW CATALYST CONTENT.
