manufacturing process of phenol
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.
Phenol was first isolated from coal tar in the coking of coal, but the first commercial process was the sulphonation of benzene and subsequent fusion with caustic soda. There are now three synthetic routes to phenol with cumene-based technology being the dominant process. Here, benzene and ...

The present invention provides in a particular embodiment an improvement in the process for producing phenol by the acid-catalyzed cleavage of cumene hydroperoxide (CHP). The reactant stream fed to the cleavage reactor also includes the contaminant by-product dimethyl benzyl alcohol (DMBA) formed during the direct oxidation of cumene to CHP.
The overall process, from benzene to phenol and propanone, is: If we assume that both phenol and propanone are desired products, and that the yield is , this will clearly give an atom economy of - all the atoms in the reactants appear in the products.
The coproduction of acetone from the cumene peroxi- dation phenol process in 1982 could account for approximately 71% of the projected acetone demand. However, since acetone is a product of phenol production, strong phenol demand could cause an acetone surplus.
This is a supplement to Process Economics Program Report No. 22 issued in April 1967. In the current report, the cumene process, which is the dominating process for manufacturing phenol, is completely revised to get a more accurate economic evaluation. The …
Even the chemistry, let alone the production engineering of the key steps, underwent a radical change, a development which allowed the modern cumene process for phenol manufacturing to dominate over alternative methods; to attain a level of selectivity very close to the theoretical value, 97 mol %; and, accordingly, to reduce the yield of ...
Phenol is often used in the allergy extract manufacturing process as a preservative. However, phenol can denature proteins in allergenic extracts. 1 To safeguard against potency loss, our glycerinated extracts contain no phenol. The table below illustrates the effect of phenol on potency over time. Quality and Consistency ENTs Can Trust
Phenol manufacturers, service companies and distributors are listed in this trusted and comprehensive vertical portal. The comprehensive directory provides access to full contact and ability information for sourcing professionals, engineers and researchers wishing to get information on Phenol.
Material Balances Design Problem Cumene Production Background Cumene (isopropyl benzene) is produced by reacting propylene and benzene over an acid catalyst. Cumene may be used to increase the octane in gasoline, but its primary use is as a feedstock for manufacturing phenol and acetone.
Production Methods Summary: Alternatives. One alternative method that has been in use since 1961 makes phenol by oxidising methylbenzene (toluene). The main advantage of this process is that phenol is the only major product, so there is no dependence on the market for any other by-product. ...
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.
Phenol, Acetone, Cumene 09/10-4 Report Abstract 1 PERP 00101.0010.4105 Phenol, Acetone, Cumene INTRODUCTION The focus of this report is phenol. The main use of cumene is as a feedstock for phenol production. Acetone is co-produced in the process. Cumene based routes to phenol are responsible for virtually all global production of phenol. Key
Jan 15, 2016· Phenol is an aromatic organic compound which is widely used as a precursor or an intermediate in the chemical industry. Represented by the chemical formula C6H5OH, phenol is similar to alcohols as the phenyl group (C6H5) in it is bonded to a hydroxyl group (OH).
Dec 02, 2016· In the separation process, the side product and waste are removed to get the primary product i.e. Phenol. Basic Process Flow Diagram and background. Figure 5: Block diagram for the process of Phenol. So as to do a simulation the phenol production process is composed of two processes i.e. oxidation and cleavage of Cumene. Hock process (oxidation ...
