Existing phenol production mostly by cumene processes is a threestep route with unwanted acetone as byproduct. Here, we report the FeCl 3 and mesoporous carbon nitride hybrid (FeCl 3 /mpgC 3 N 4) as an active and selective photoalyst to activate H 2 O 2 for the oxidation of benzene to phenol under visiblelight illumination. By fineoptimizing FeCl 3 loading amount in alyst and ...

acetone. Phenol, acetone, unconverted cumene, and byproducts are then distilled in a series of distillation towers to recover high purity phenol and acetone products and to recover cumene to be recycled to reaction. Fresh and recycle cumene are fed to a series of oxidizers where the cumene contacts air and is converted to CHP. The oxidate is concentrated in a multistage cumene stripping ...
· INEOS Phenol and Sinopec Yangzi Petrochemical Company (Sinopec YPC) have today initialled joint venture agreements for the design, build and future operation of a tonne cumene, phenol and acetone complex at the Nanjing Chemical Industrial Park in Jiangsu Province, China. It is currently expected that the project will be completed by the end of 2015.
· SRI Phenol Cumene is oxided with air at 103 113 C and atm to convert about 20% of the cumene to the hydroperoxide solution. It is then decomposed to phenol and acetone by using sulfuric acid as a alyst. The phenol and acetone by residual unreacted cumene are separated by distillation. The cumene is recycled
· In phenol production process, separation of excess cumene from cumene hydroperoxide is critical. The cumene mole fraction in upstream flow of distillation column was selected as the output response. The major novelties of this study are applying the DoE method, simulation of the process using AspenHysys, and developing a model based on ANN as well as process optimization. RSM was .
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 production and processing from petroleum refining, the evaporation and combustion of petroleum products, and by the use of a variety of products containing ...
phenol is obtained by the oxidation of cumene to form cumene peroxide, which is then cleaved into phenol and acetone in a threestep process involving oxidation of cumene. The first step is the alkylation of benzene with propylene to cumene in the presence of zeolitebased alysts. The reaction can also be performed with Friedel Crafts alysts such as aluminium trichloride at 373473 K ...
phenol. However, acetone manufactured thus generally contains small amounts of the reactant benzene and the desired product phenol [1]. In the past, these impurities were deemed to be within allowable limits. However, recent downward revisions of these limits by the US Food and Drug Administration has made alternative processes (which do not involve benzene) more attractive. We wish to begin ...
derivative substances including phenol, acetone, cumene, alphamethyl styrene, acetophenone, diisopropyl benzene, and "high boiler". 8 Dominance Analysis Table 3 shows the main contributions to the results presented above. Although the absolute results are different for 1 kg Phenol or 1 kg Acetone, the relative contribution is the same due to the used alloion approach (alloion by energy ...

with cumene, which is the primary feedstock and with acetone, which is the primary coproduct. Phenol and cumene production processes have been extensively reviewed by PEP in several reports and reviews since 1967. In this PEP process summary, we review various production technologies for phenol and cumene, based on PEP reports. Salient features of the production economics for various current ...
Crystalline, microporous molecular sieves efficiently alyse the selective decomposition of cumene hydroperoxide into phenol and acetone, both under batch (25 °C) and downflow fixedbed (60 °C) conditions; largepore highsilica zeolites, mainly zeolite Beta and its metallosilie (B, Fe and Gasilie) analogues, are found to be particularly useful alysts in this reaction giving ...
This preview shows page 4 7 out of 34 pages. : 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. Cumene process is a process of producing phenol (C6H5OH) and acetone (CH3 ...
Phenol, Acetone Cumene Petrochemicals Europe. Issues and Regulations REACH Implementation. A "Phenol Acetone" REACH Consortium was formed through which manufacturers have joined efforts to prepare by 30 November 2010 consistent registration dossiers covering phenol and its derivative substances including phenol, acetone, cumene, alphamethyl styrene, acetophenone, diisopropyl .
Phenol, benzene and cumene as well as acetone are produced in Finland and are sold mainly to the adhesive, fibre, epoxy resin and polycarbonate industries in Northern Europe. In the Nordic and Baltic regions, Borealis is the leading producer of phenol, which is used in adhesives, construction materials, carpets, CDs, DVDs, mobile phones and appliances. Acetone is commonly used in ...

Phenol is derived from benzene and propylene. These raw materials are first used to produce cumene, which is then oxidised to become cumene hydroperoxide, before being split into phenol and its coproduct, acetone. Phenol plays a major role in our everyday lives. Plywood, window glazing, DVDs and CDs, computers, sports equipment, fibre glass ...
Phenol is primarily produced from cumene, although it can also be made from benzoic acid or chlorobenzene. Phenol's main uses are in the manufacture of phenolic resins, for plywood and moulding powders, and in bisphenol A (BPA) an intermediate for the manufacture of epoxy and polycarbonate resins. Phenol can also be used to produce caprolactam. Acetone: Acetone is primarily used as a ...
