Technology Profile: Cumene Production from Benzene

By Intratec Solutions |

This column is based on “Cumene from Benzene and RG Propylene (Zeolite Catalyst) – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/cumene-production-cost. Cumene (also known as isopropylbenzene) is an organic compound of the aromatic hydrocarbon class. It is a colorless liquid, insoluble in water, but soluble in most organic solvents. The production of cumene grew rapidly during World War II, when this aromatic compound was used as a component of aviation fuel. Today, cumene is mainly employed as an organic solvent in pharmaceutical manufacturing and as a flow-control agent for thermoplastic elastomer processing. Cumene derivatives (mainly phenol, acetone, and methyl styrene) are compounds with many chemical and industrial uses. Currently, the production of cumene is largely associated with the demand for phenol and phenol derivatives. Figure 1. The diagram show cumene production from benzene and propylene[/caption] The process The present analysis discusses an industrial process for cumene production. The process has two main sections: (1) reaction; and (2) distillation. Reaction. In the reaction section, there are two reactors: the alkylation reactor and the transalkylation…
