Phenol

2019-10-15 · Phenol is an aromatic organic compound with the molecular formula C6H5OH. It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH). It is mildly acidic and requires careful handling due to its propensity for causing chemical burns. Phenol was first extracted from coal

2019-10-27 · phenol-e11a Phenol Phenol Production from Cumene. This report presents an up-to-date, detailed cost analysis of Phenol production from cumene. The process examined is a typical hydroperoxidation process. In this process, acetone is generated as by-product.

Production of phenol from cumene

CONTINUOUS PROCEDURE FOR THE PREPARATION OF PHENOL FROM CUMENE In order to be able to study the overall process an apparatus was developed for the continuous preparation of phenol and acetone from cumene on a small scale. The procedure was based on the results of the experiments discussed in the foregoing chapters.

Cumene

2019-10-29 · Ultimately, it is the strong growth in polycarbonate resin that is driving demand through BPA to phenol/acetone and back to cumene. The cumene peroxidation process is the largest source of phenol and acetone production. However, the ratio of phenol and acetone produced does not match up with the ratio of phenol and acetone consumed.

Phenol Process Celebrates Its 60th Anniversary

2003-3-14 · the modern up-to-date phenol process [6], are (1) the introduction of cumene as an initial feed, and (2) the production of phenol and acetone as the desired pro-ducts. Even the chemistry of the reactions, disclosed in [6], not to mention the design of the process itself, have been markedly changed. Nevertheless, without this giant

Cumene process

The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. Hydroquinone, also known as benzene-1,4-diol, is prepared by dialkylation of benzene with propene to give 1,4-diisopropylbenzene.

Cumene Benzene Alkylation | ExxonMobil Chemical

ExxonMobil's zeolite catalysts are the heart of the Badger Cumene process. Originally developed by Mobil Oil, the MCM-22 family of zeolite catalysts revolutionized the production of cumene. high-quality cumene from every commercial grade of propylene and its cumene product has been a feedstock to every major Phenol process technology.

The cumene process for phenol-acetone production

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

How to convert cumene to phenol

This is an old industrial process. Cumene (isopropylbenzene) is oxidized with air in the presence of a cobalt catalyst. The product is cumene hydroperoxide, which is to say PhCMe2OOH. When the hydroperoxide is heated in dilute sulfuric acid, it fragments into phenol …

Cumene

The cumene process (Scheme 1), developed by Hock and Lang, 24 is by far the most important synthetic process 19, 20 for the production of phenol, and accounts for more than 95% of the synthetic phenol capacity in the Western world today. In addition to the cumene synthesis process, about 3% of phenol is derived from coal.

Design and Control of the Cumene Process | Industrial

2009-7-18 · The chemistry of the cumene process features the desired reaction of benzene with propylene to form cumene and the undesirable reaction of cumene with propylene to form p-diisopropylbenzene. Both reactions are irreversible. Since the second has a higher activation energy than the first, low reactor temperatures improve selectivity of cumene.
