What is the mechanism of the cumene phenol process?
This process converts two relatively cheap starting materials, benzene and propylene, into two more valuable ones, phenol and acetone. Other reactants required are oxygen from air and small amounts of a radical initiator. Most of the worldwide production of phenol and acetone is now based on this method.
Which of the following reaction result in the formation of cumene?
The synthesis of cumene is by Friedel Crafts alkylation reaction of benzene in which the benzene gets substituted by propylene. This cumene if given long exposure to air gives cumene peroxides.
What means cumene?
: a colorless oily hydrocarbon (CH3)2CHC6H5 obtained by acid-catalyzed alkylation of benzene with propylene and used as an additive for high-octane motor fuel; isopropyl-benzene.
Who produces cumene?
Cumene technology leadership ExxonMobil continues to be one of the leading cumene catalyst suppliers in the world. As of early 2018, ExxonMobil catalysts were deployed to 24 customers around the world in the Badger Cumene process.
What is the formula of cumene hydroperoxide?
C9H12O2
Cumene hydroperoxide/Formula
What is another name for cumene?
isopropylbenzene
Cumene, also known as isopropylbenzene, 2-phenylpropane, or (1-methylethyl) benzene, is a colorless, volatile liquid with a gasoline-like odor.

What’s the reaction process for the synthesis of cumene?
The reaction process for the synthesis of cumene involves the Friedel-Crafts alkylation of benzene with propylene as shown in Figure 1. This process typically involves temperatures greater than 350 ºC and 30 bar.
How is the cumene process related to the Hock process?
From Wikipedia, the free encyclopedia The cumene process (cumene–phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material during the process.
How is the production of cumene related to phenol?
About This Process Essentially all cumene produced worldwide is used as a feedstock in phenol plants, which convert it to phenol and acetone by cumene peroxidation. Therefore, the cumene and phenol markets are strongly tied. From 1993 to 1998, world cumene demand grew at a rate of 4.7%/yr, increasing from 5.6 million to 7.1 million t/yr.
How is cumene used in the petrochemical industry?
Cumene in the global petrochemical industry is used primarily as a reactant for production of phenol. Benzene and propylene, the two reactants used to create cumene, are produced primarily as a byproduct of crude oil refining.
