1. A process for alkylating an aromatic compound comprising
(a) reacting a first amount of at least one aromatic compound with an amount of a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, in the presence of a strong acid catalyst; and
(b) reacting the product of (a) with an additional amount of at least one aromatic compound and an additional amount of a strong acid catalyst and, optionally, with an additional amount of a mixture of olefins selected from olefins having from about 8 to about 100 carbon atoms, wherein the resulting product comprises at least about 80 weight percent of a 1,2,4 tri-alkylsubstituted aromatic compound.
