A PROCESS FOR PRODUCING AN AROMATIC POLYCARBONATE RESIN BY MELT POLYCONDENSING AN AROMATIC DIHYDROXY COMPOUND AND AN AROMATIC CARBONIC ACID DIESTER, WHEREIN A MIXTURE SOLUTION COMPRISING THE SAME AROMATIC MONOHYDROXY COMPOUND AS A AROMATIC MONOHYDROXY COMPOUND BY-PRODUCED FROM A REACTION SYSTEM AS A MAIN COMPONENT AND A FREEZING-POINT DEPRESSANT FOR THE AROMATIC MONOHYDROXY COMPOUND, SUCH AS A GLYCOL, IS USED AS A SCRUBBING SOLUTION FOR THE RECOVERY OF THE BY-PRODUCED AROMATIC MONOHYDROXY COMPOUND BY A SCRUBBER TYPE CONDENSER.
