09-12-2015· Isopropylbenzene, or cumene, is traditionally a key component in global phenol production. With a 2011 market demand of 12.4 million tons (Stephan 2013), this makes cumene production nearly a 20 billion dollar per year industry. Nearly all of the cumene produced in the world uses
Global Cumene Market was valued at $16,330 million in 2015, and is expected to reach $25,089 million by 2022, supported by a CAGR of 6.5% during the forecast period 2016 to 2022. Cumene in chemical form is known as isopropyl benzene, an organic compound based on aromatic hydrocarbons with aliphatic substitution.

Acetone from cumene - Big Chemical Encyclopedia Big Chemical Encyclopedia Chemical substances, components, reactions, process design Articles;, Most of the world s manufactured acetone is obtained as a coproduct in the process for phenol from cumene and most of the remainder from the dehydrogenation of isopropyl alcohol, Figure 10-7 is a simplified ...
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. It was invented by R. Ūdris and P. Sergeyev in 1942 (USSR)., and independently by Heinrich Hock in 1944 ...
The cumene process for phenol–acetone (PA) manufacture is one of the unique high-volume petrochemical processes in which simultaneously two products (phenol and acetone) are obtained from one reactant (cumene), each of the products finding useful application; however, which is most important, their reaction with one another in the joint synthesis results in bisphenol, a chemical that forms ...
Phenol Essential Chemical Industry. The vast majority of phenol is made by the cumene process The process has three stages a) production of cumene b) conversion of cumene to cumene hydroperoxide c) decomposition of cumene hydroperoxide (a) Production of cumene Cumene is the name often given to (1 methylethyl)benzene (isopropylbenzene)
USA - Recovery of acetone and phenol from cumene ... to produce phenol as a raw material at a cheaper cost than the current market price of $0.64/lb. The production rate of concern is 190,000 metric tons per year. Basic Flow Diagram and Process Background The phenol production process is based on the oxidation and cleavage of cumene.
Around 98% of cumene is used to produce phenol and its co-product acetone. However, the requirement of cumene is largely dependent on the use of phenol's derivatives which have resulted in increasing requirement rates for cumene. The largest phenol derivative is bisphenol-A (BPA) which supplies the polycarbonate (PC) sector.
Cumene is used as a thinner for paints, lacquers, and enamels and as a component of high octane fuels. (1,2,4) Cumene is also used in the manufacture of phenol, acetone, acetophenone, and methylstyrene. (1,8) Sources and Potential Exposure Cumene is a constituent of crude oil and finished fuels. It is released to the environment as a result of its
