A process is described for converting a first hydrocarbon mixture to a second hydrocarbon mixture. The first hydrocarbon mixture consists essentially of aromatic hydrocarbons having 10 or more carbon atoms. The first hydrocarbon mixture comprises at least 50% by weight of diisopropylbenzene and less than 5% by weight of the sum of benzene, toluene, xylene and ethylbenzene. The second hydrocarbon mixture consists of at least 30% by weight of the sum of benzene, toluene, xylene and ethylbenzene and less than 20% by weight of diisopropylbenzene, the process comprising cracking the first hydrocarbon mixture over a catalyst comprising a mixture of zeolites, the mixture of zeolites consisting essentially of from about 10% to about 90% by weight of ZSM-5, the remainder being essentially ZSM-12.
