Organic aromatic compounds are alkylated in a Reactive DistillationTMreactor, wherein the solid particulate catalyst is slurried in the aromatic feed stream and fed to a reaction zone containing inert distillation packing. Olefin is vaporized and fed to the bottom of the reaction zone and agitates the catalyst while reacting the olefin with the aromatic to form an alkylation product. The alkylation product is removed from the lower end of the reaction zone and recovered. Any unreacted aromatic is distilled overhead and recycled or recovered. Recycling the aromatic controls the molar ratio of aromatic to olefin to the extent that substantially all of the olefin is reacted.

A process for the alkylation of organic aromatic compounds comprising the steps of: (a) slurrying a solid particulate acidic catalyst in an organic aromatic compound stream; (b) concurrently: (i) feeding said slurried catalyst and said organic aromatic compound to a distillation column reactor in a reaction-distillation zone, said zone containing inert distillation packing, said slurried catalyst moving downward through said inert packing; (ii) feeding a C2 to C20 olefin to said reaction-distillation zone thereby contacting said olefin with said organic aromatic compound in the presence of said slurried catalyst to react said olefin with said organic aromatic compound to form an alkylation compound; and (iii) fractionating the resultant alkylation product and the unreacted organic aromatic compound and olefin in said distillation column reactor; and (c) withdrawing said alkylation product from said distillation column reactor at a point below said reaction zone.
