Procedure

The second stream 325 enters a second separation zone 360 to separate the second stream 325 into at least a di-isopropylbenzene stream 365 and a cumene stream 370. The di-isopropylbenzene stream 365 is provided to a second transalkylation zone 375 to transalkylate at least a portion of the di-isopropyl benzene with pure benzene in the presence of a transalkylation catalyst, forming a cumene product stream 380. The cumene product stream 380 is then recycled to the second separation zone 360.

Workup

  1. customto separate the second stream 325 into at least a di-isopropylbenzene stream 365
  2. customThe di-isopropylbenzene stream 365 is provided to a second transalkylation zone 375
