Abstract
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.

A process for dealkylating a poly-alkylated aromatic compound, the process comprising:
- (a) introducing a feed comprising at least one poly-alkylated aromatic compound selected from polypropylbenzene, polybutylbenzene, and polycyclohexylbenzene into a reaction zone;
- and
- (b) contacting the feed in the reaction zone with an acid catalyst under conditions effective to dealkylate at least a portion of the poly-alkylated aromatic compound to produce a first reaction product comprising (i) a first compound comprising at least one mono-alkylated aromatic compound and (ii) a second compound comprising at least one compound selected from an alkane and alkene.
