Process for the purification of high molecular weight aralkyl compounds

Claim 1

PROCESS OF PURIFYING CRUDE, WATER-FREE ALKYL AROMATIC COMPOUNDS PRODUCED BY REACTING ALKYL CHLORIDES CONTAINING MORE THAN 10 CARBON ATOMS WITH BENZENE HYDROCARBONS BY THE FRIEDEL-CRAFTS METHOD WHICH COMPRISES SEPARATING THE CRUDE ALKYL AROMATIC COMPOUNDS FROM ALUMINUM CHLORIDE DOUBLE COMPOUND, WASHING THE RESULTING SEPARATED CRUDE ALKYL AROMATIC COMPOUNDS TO NEUTRALITY, SEPARATING UNREACTED BENZENE HYDROCARBONS THEREFROM, INITIMATELY CONTACTING, THE RESULTING SEPARATED, WATER-FREE AND BENEZENE HYDROCARBON-FREE CRUDE, ALKYL AROMATIC COMPOUNDS WITH FROM ABOUT 0.5% TO ABOUT 5% BY WEIGHT OF ALUMINUM CHLORIDE IN THE PRESENCE OF GASEOUS HYDROGEN CHLORIDE AT ABOUT ROOM TEMPERATURE AND SEPARATING THE RESULTING PURIFIED ALKYL AROMATIC COMPOUNDS FROM THE RESULTING LIQUID ALUMINUM CHLORIDE DOUBLE COMPOUND.
