Method for separating organolead compounds

Claim 1

A PROCESS FOR RECOVERING A HYDROCARBON LEAD COMPOUND FROM A LIQUID MIXTURE INCLUDING THE LEAD COMPOUND AND ANOTHER ORGANOMETALLIC COMPOUND, THE HYDROCARBON LEAD COMPOUND HAVING AT LEAST ONE HYDROCARBON RADICAL BONDED TO THE LEAD THROUGH A CARBON ATOM AND THE REMAINING VALENCES THEREOF BEING SATISFIED BY LEGANDS SELECTED FROM THE GROUP CONSISTING OF HALOGENS, HYDROGEN, AND ALCOHOLATE GROUPS HAVING UP TO ABOUT 18 CARBON ATOMS IN THE ALCOHOL RESIDUES THEREOF, SAID OTHER ORGANOMETALLIC COMPOUND BEING A HYDROCARBON COMPOUND OF AN ELEMENT SELECTED FROM THE GROUP CONSISTING OF ZINC, CADMIUM, AND GROUP III-A ELEMENTS, AND HAVING AT LEAST ONE HYDROCARBON RADICAL BONDED TO THE ELEMENT BY A CARBON ATOM, THE REMAINING VALENCES THEREOF BEING SATISFIED BY LEGANDS SELECTED FROM THE GROUP CONSISTING OF HALOGENS, HYDROGEN, AND ALCOHOLATE GROUPS HAVING UP TO ABOUT 18 CARBON ATOMS IN THE ALCOHOL RESIDUES THEREOF, SAID PROCESS COMPRISING REACTING THE LIQUID MIXTURE WITH A COMPLEXING COMPOUND CAPABLE OF COMPLEXING WITH SAID OTHER ORGANOMETALLIC COMPOUND OF THE LIQUID MIXTURE, NONREACTIVE WITH THE HYDROCARBON LEAD COMPOUNDS, AND SELECTED FROM THE GROUP CONSISTING OF HYDRIDES, HALIDES, PSEUDOHALIDES, AND HYDROCARBON COMPOUNDS OF ALKALI AND ALKALINE EARTH METALS, AND SAID COMPLEXING COMPOUND BEING PROVIDED IN PROPORTIONS OF AT LEAST ABOUT 1/2 MOLE PER MOLE OF SAID OTHER ORGANOMETALLIC COMPOUND TO FORM A COMPLEX IMMISCIBLE WITH THE HYDROCARBON LEAD COMPOUND, AND SEPARATING SUBSTANTIALLY PURE HYDROCARBON LEAD COMPOUND FROM THE COMPLEX.
