Title:
AROMATIC ALKYLATION PROCESS WITH REDUCED BYPRODUCT FORMATION
Document Type and Number:
WIPO Patent Application WO/2010/135062
Kind Code:
A3
Abstract:
Byproduct formation in aromatic alkylation processes is reduced when different polyalkylated aromatic compounds are first fractionated into separate streams enriched in these respective polyalkylated aromatic compounds, and the separate streams are sent to different transalkylation reaction zones, which may or may not be in the same reactor. The different transalkylation reaction zones allow for greater control of the transalkylation of the respective polyalkylated aromatic compounds, such as diisopropylbenzene (DIPB) and triisopropylbenzene (TIPB) that accompany the alkylation of benzene with propylene in a process for cumene production.
