Cumene 98-82-8 National Toxicology Program

Cumene 98-82-8 The most common process for making cumene uses an adiabatic reactor for the consumption was 95% for phenol and acetone production and 5% for a-

Cumene manufacturing procedure | Chemical Reactor

b) The process requires a relatively high benzene propylene molar feed ratio on the order of 7/1 to maintain cumene yield. g) Meets evolving environmental requirements. f) Continuous process. Q-Max Process and CD-Cumene process doesn't have any disadvantage. lavel Page 17 .2. But from this two processes CD-Cumene process is more effective than Q-max process because. d) Improves economics.

Cumene | Honeywell UOP

Leading process solution to convert propylene and benzene to cumene. Cumene is the primary building block for making phenol and its derivatives. UOP delivers the latest generation of cumene technology based on highly-selective, stable and regenerable zeolite catalysts.

Cumene Revolvy

The cumene process ( cumene-phenol process, Hock process ) is an industrial process for developing phenol and acetone from benzene and propylene . The term stems from cumene (isopropyl benzene), the intermediate material during the process.

Cumene | pricing updates | market intelligence and news

Cumene is the main feedstock for phenol/acetone production and nearly all is used in this way. Demand is driven by market growth for the derivatives of phenol such as bisphenol-A (BPA) and phenolic resins.

Acetone Production and Manufacturing Process ICIS

The main process for manufacturing cumene involves the reaction of propylene and benzene in the presence of phosphoric acid-based catalysts or, more recently, zeolite catalysts. The cumene is oxidised in the liquid phase to cumene hydroperoxide which is then cleaved in the presence of sulphuric acid to phenol and acetone.

Source Assessment: Manufacture of Acetone and Phenol From

The cumenebased process accounts for approximately 60% or 831 x 103 metric tons of installed annual acetone capacity of 1,380 x 103 metric tons. Location of Plants Manufacturing Acetone and Phenol from Cumene There are currently 10 locations in the continental United States where phenol and acetone are produced from cumene (2, 3).

"What's New in Phenol Production?" American Chemical Society

Hock process. In the Hock process (Figure 2), cumene (1, made by alkylating benzene with propylene) is oxidized to cumene hydroperoxide (2), which is then cleaved to a mixture of phenol (3) and acetone (4) by treating it with H2SO4.

Phenol Essential Chemical Industry

The cumene process has one problem. Six tonnes of propanone are produced for every ten tonnes of phenol. Thus, for economic efficiency, the manufacturer needs to sell the two compounds in that proportion. Often, much more phenol is needed than the propanone that is produced at the same time.

-1 -1 -1 -1 Key-words Cumene CHP catalyst selectivity oxidation rate 5 .h and a selectivity to CHP around 93-95%. It is needed to establish an optimized balance between oxidation rate of cumene and selectivity to CHP. With this catalyst. the key reaction of a phenol production industrial process.

PROCESS DESCRIPTION ON CUMENE PLANT KFUPM

Cumene is mainly used for the manufacturing of Phenol and Acetone. Cumene is oxidized with air to get Cumene Hydro Peroxide (CHP). This CHP is cleaved to get Phenol and Acetone.
