Procedure

In a reactor fitted with a stirrer and a reflux condenser were placed aluminum chloride and 250 g of the polyethylbenzene fraction (containing 91% of diethylbenzenes, 7% of triethylbenzenes, and 2% of others) obtained as by-product in the manufacture of ethylbenzene by the alkylation of benzene with ethylene in the presence of 25 g of aluminum chloride, the mixture was heated, and ethylene was supplied to the mixture at a given rate to effect the ethylation.
