Napthalene extraction process utilizing polynitro aromatic compounds as complexors

Claim 1

A PROCESS FOR SEPARATING FUSED POLYCYCLIC AROMATIC COMPOUNDS FROM HYDROCARBON STOCKS CONTAINING THE SAME WHICH COMPRISES CONTACTING THE HYDROCARBON STOCK IN A LIQUID PHASE WITH AN AMOUNT OF A LIQUID PHASE SOLUTION OF A POLYNITRO AROMATIC COMPOUND, WHICH IS A COMPLEXOR FOR SAID AROMATIC COMPOUNDS, IN A SOLVENT CONSISTING ESSENTIALLY OF A GLYCOL AND WATER, WHICH IS SUBSTANTIALLY IN SOLUBLE IN SAID HYDROCARBON STOCK, TO DISSOLVE THE COMPLEX FORMED BETWEEN THE POLYNITRO AROMATIC COMPLEXOR AND THE FUSED POLYCYCLIC AROMATIC COMPOUNDS SO THAT THE COMPLEX REMAINS DISSOLVED IN THE LIQUID COMPLEXOR SOLUTION PHASE, SAID AMOUNT OF LIQUID PHASE COMPLEXOR SOLUTION BEING SUFFICIENT TO FORM THE COMPLEX AND GREATER THAN THE AMOUNT TO FORM A SOLID COMPLEX, AND THE AMOUNT OF COMPLEXOR IN SAID SOLUTION BEING AT LEAST THE THEORETICAL AMOUNT TO FORM A COMPLEX WITH SAID FUSED POLYCYCLIC AROMATIC COMPOUNDS, SEPARATING THE LIQUID HYDROCARBON PHASE FROM THE LIQUID COMPLEXOR SOLUTION PHASE CONTAINING THE COMPLEX IN SOLUTION, DECOMPOSING THE COMPLEX WHILE CONTAINED WITHIN THE LIQUID COMPLEXOR SOLUTION PHASE TO RECOVER SAID AROMATIC COMPOUND DIRECTLY THEREFORM, AND RECYCLING THE LIQUID COMPLEXOR SOLUTION PHASE TO TREAT AN ADDITIONAL AMOUNT OF STOCK.
