Kaeding, W W

A method is described for the preparation of isopropylbenzene from benzene and a mixture of propane and propylene, wherein a heavy aromatic bottoms fraction is produced as a byproduct, the bottoms fraction consisting essentially of hydrocarbons having 10 or more carbon atoms, the improvement comprising cracking the bottoms fraction over a catalyst comprising a mixture of zeolites. The mixture consists of: (i) from about 10% to about 90% by weight of ZSM-5; and (ii) from about 10% to about 90% by weight of ZSM-12.
