Patent ID: 7488861

Claim:
A process for the concurrent production of cumene and secondary butyl benzene comprising the steps of: (a) feeding a first stream consisting essentially of benzene and a second stream consisting essentially of propylene and butylene to a distillation column reactor containing a bed of alkylation catalyst; (b) concurrently in said distillation column reactor; (i) reacting a portion of said benzene with a portion of said propylene and said butylene to form a reaction mixture containing unreacted benzene, unreacted propylene, unreacted butylene, cumene and secondary butyl benzene; (ii) separating the unreacted benzene, unreacted propylene and unreacted butylene from the cumene and secondary butyl benzene by fractional distillation; (c) removing the unreacted benzene, unreacted propylene and unreacted butylene from said distillation column reactor as overheads; and (d) removing the cumene and secondary butyl benzene from said distillation column reactor as bottoms.
