In a process for dealkylating a poly-alkylated aromatic compound, a feed comprising at least one poly-alkylated aromatic compound selected from polypropylbenzene, polybutylbenzene, and polycyclohexylbenzene is introduced into a reaction zone. The feed is then contacted in the reaction zone with an acid catalyst under conditions effective to dealkylate at least a portion of the poly-alkylated aromatic compound and produce a first reaction product comprising at least one mono-alkylated aromatic compound.
