This enzyme is an important component of cellular metabolism for the elimination of formaldehyde, a potent irritant and sensitizing agent that causes lacrymation, rhinitis, pharyngitis, and contact dermatitis. Information on applicable regulatory frameworks is also automatically generated and may not be complete or up to date. Many phenolic compounds were discovered and used long before chemists were able to determine their structures. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. The resin curing behavior, molecular structure, bonding performance, and properties of resin-impregnated wood were investigated. This substance has not been registered under the REACH Regulation, therefore as yet ECHA has not received any data about this substance from registration dossiers. For readability purpose, only non-confidential use descriptors occurring in more than 5% of total occurrences are displayed. Precautionary statements - describe recommended measures to minimise or prevent adverse effects resulting from exposure to a hazardous product or improper storage or handling of a hazardous product. The InfoCard summarises the non-confidential data of a substance held in the databases of the European Chemicals Agency (ECHA). The Dow process is somewhat more general, but the stringent conditions required often lead to low yields, and they may destroy any other functional groups on the molecule. [provided by RefSeq, Oct 2008] Please note: Precautionary measures and guidance on safe use concern the use and handling of the specific substance as such, not of the presence of the substance in other articles or mixtures. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. We apologise for the inconvenience in the meantime. Many of the more complex phenols used as flavourings and aromas are obtained from essential oils of plants.

An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the... Get exclusive access to content from our 1768 First Edition with your subscription. Phenol, any of a family of organic compounds characterized by a hydroxyl (―OH) group attached to a carbon atom that is part of an aromatic ring. It covers their hazardous properties, classification and labelling, and information on how to use them safely. Lignin is a good candidate to replace phenol in the phenol formaldehyde resinsâ formulation because (a) its polyphenolic structure is similar to that of phenolic resin (Fig. Phenol formaldehyde; Structure of Bakelite. For example, the systematic name for thymol is 5-methyl-2-isopropylphenol. ECHA has no public registered data indicating whether or into which articles the substance might have been processed. in case of consumer and professional uses). Phenolic resins are a group of the most versatile polymers yet invented. The information is aggregated from the data coming from REACH substance registrations provided by industry. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. Note that for readability purposes, only the pictograms, signal words and hazard statements referred in more than 5% of the notifications under CLP are displayed. Phenol-formaldehyde resins are inexpensive, heat-resistant, and waterproof, though somewhat brittle. ECHA has no public registered data indicating whether or in which chemical products the substance might be used. The Waste Framework Directive aims to protect the environment and human health from the generation and management of waste and to improve efficient use of resources. Additionally, if available, information on the use of the substance and how consumers and workers are likely to be exposed to it can also be displayed here. Uses of Formaldehyde â CH 2 O. 1) (Forss and Fuhrmann1979), (b) the material comes from renewable resources, and (c) it can be used as a macromolecular material without previous treatment (Nimz 1983; Pang et al. the products in which the substance may be used) may refer to uses as intermediate and under controlled conditions, for which there is no consumer exposure. The noncovalently adsorbed phenol on the RGO surface can not only serve as an ⦠More information about CAS and the CAS registry can be found here. Phenols are similar to alcohols but form stronger hydrogen bonds. Public (risk management) activities co-ordination table.

ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. Hydrolysis of chlorobenzene (the Dow process), https://www.britannica.com/science/phenol, National Center for Biotechnology Information - PubChem - Phenol. The simplest way to draw the structure of phenol is: Harmonisation is based on the substance’s physical, toxicological and eco-toxicological hazard assessment. Individual Protection Measures, Such as Personal Protective Equipment 28064-14-4 - Phenol, polymer with formaldehyde, glycidyl ether - Searchable synonyms, formulas, resource links, and other chemical information. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation. The per substance REACH registration status is being calculated and will be made available as soon as possible. In 1865 the British surgeon Joseph Lister used phenol as an antiseptic to sterilize his operating field. Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. Phenol, the cresols (methylphenols), and other simple alkylated phenols can be obtained from the distillation of coal tar or crude petroleum. In the presence of oxygen in the air, many phenols slowly oxidize to give dark mixtures containing quinones. Most functional groups can survive this technique, as long as they are stable in the presence of dilute acid. Substances listed in the EINECS, ELINCS, or NLP inventories. Phenoxide ions, generated by treating a phenol with sodium hydroxide, are so strongly activated that they undergo electrophilic aromatic substitution even with very weak electrophiles such as carbon dioxide (CO2). Picric acid (2,4,6-trinitrophenol) is an important explosive that was used in World War I. It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration (e.g. Unexposed grains of silver bromide react more slowly than the exposed grains. In industry, phenol is used as a starting material to make plastics, explosives such as picric acid, and drugs such as aspirin. InfoCards are generated automatically based on the data available at the time of generation. The precautionary measures and guidance on safe use are as submitted to ECHA by registrants under the REACH Regulation. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member, monohydroxybenzene (C6H5OH), also known as benzenol, or carbolic acid. What is the Classification and Labelling Inventory? REACH regulation aims to improve the protection of human health and the environment from the risks that can be posed by chemicals. Corrections? Omissions? Much of the chemistry of phenols is like that of alcohols. REACH registration dossiers have greater data requirements (such as supporting studies) than do notifications under CLP. Less-toxic phenols, such as n-hexylresorcinol, have supplanted phenol itself in cough drops and other antiseptic applications. The molecular structure is based on structures generated from information available in ECHA’s databases. A substance may have its use restricted to certain articles or products and therefore not all the examples may apply to the specific substance. The source of the information is mentioned in the introductory sentence of the hazard statements. Formaldehyde, phenol polymer. ECHA has no data from registration dossiers on the precautionary measures for using this substance. Information on precautionary measures and the safe use is submitted by the registrant of a substance and the registrant is solely responsible for its accuracy and completeness. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. The CAS number is the substance numerical identifier assigned by the Chemical Abstracts Service, a division of the American Chemical Society, to substances registered in the CAS registry database. phenol formaldehyde. Its chemical formula can also be ⦠The use information is displayed per substance life cycle stage (consumer use, in articles, by professional workers (widespread uses), in formulation or re-packing, at industrial sites or in manufacturing). Dynea produces a large volume of formaldehyde as an intermediate product, but we also supply formaldehyde in various consentrations and quality grades to the external market. Thus, they are more soluble in water than are alcohols and have higher boiling points. Three nitro groups are more easily substituted onto phenol, because the strong activation of the hydroxyl group helps to counteract the deactivation of the first and second nitro groups. The most obvious difference is the enhanced acidity of phenols. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Molecular Formula. 6HCHO + 4NH 3 â (CH 2)6N 4 + 6H 2 O. Used in the production of resins, principally urea formaldehyde and phenol-formaldehyde, which are used to make cores and moulds for foundries. The EC or list number is the primary substance identifier used by ECHA. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. In that case, the ATP (Adaptation to Technical Progress) number is displayed. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): Welcome to the ECHA website. For a detailed overview on identified uses and environmental releases, please consult the registered substance factsheet. The ‘Hazard classification’ and labelling section uses the signal word, pictogram(s) and hazard statements of the substance under the harmonised classification and labelling (CLH) as its primary source of information. Other relevant information includes the following: To see the full list of notified classifications and to get more information on impurities and additives relevant to classification please consult the C&L Inventory. Molecular Weight: 170.21. The described Product category (i.e. Catalyst levels range from 0.5% to 3%. Formaldehyde was initially manufactured in small quantities (5-20kg) for use in a few factories and university laboratories, but improvements to the manufacturing process eventually led to large-scale production of formaldehyde. This is unique source of information on the chemicals manufactured and imported in Europe. Release to the environment of this substance can occur from industrial use: formulation of mixtures. The cumene hydroperoxide reaction is fairly specific to phenol itself. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Hydrogen bonding results in higher melting points and much higher boiling points for phenols than for hydrocarbons with similar molecular weights. Properties of concern are calculated at four "levels" of certainty: The following properties of concern are calculated: The substance properties displayed in this section are derived from Harmonised classification and labelling (CLH) data, entries in the Candidate list of substances of very high concern for authorisation, the PBT assessment list, the ED assessment list, REACH registered dossier data and from notifications made under CLP. Novolaks (sometimes: novolacs) are low molecular weight polymers derived from phenols and formaldehyde.They are related to Bakelite, which is more highly crosslinked.The term comes from Swedish "lack" for lacquer and Latin "novo" for new, since these materials were envisioned to replace natural lacquers such as copal resin..

The ‘Properties of concern’ section shows ECHA-assigned graphical indicators for certain substance properties that are regarded as being of relevance or importance to human health and/or the environment based on the information provided to the Agency. the electronic edition of the Official Journal of the European Union. They are formed through the reaction of phenol with formaldehyde, followed by cross-linking of the polymeric chains. Molecular Formula C 7 H 8 O 2; Average mass 124.137 Da; Monoisotopic mass 124.052429 Da; ChemSpider ID 150578 The structure of phenol. During this time formaldehyde was mainly used as an embalming agent or medical preservative, but these early uses represent less than 1% of total formaldehyde sales today. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. Formaldehyde is made of methanol and phenol from benzene using the cumene process. This substance is used in the following areas: formulation of mixtures and/or re-packaging and building & construction work. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. Phenol/formaldehyde resins used to manufacture high-pressure laminates are typically produced by reacting phenol and formaldehyde by means of an alkaline catalyst such as sodium hydroxide [10]. If generated, an InChI string will also be generated and made available for searching. Phenol dissolves to give a 9.3 percent solution in water, compared with a 3.6 percent solution for cyclohexanol in water.

Author of. A majority of data submitters agree this substance is Skin sensitising. Phenol is quite toxic, however, and concentrated solutions cause severe but painless burns of the skin and mucous membranes. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. ECHA has no public registered data indicating whether or in which chemical products the substance might be used. Guidance on safe use - recommendations by substance registrant on the proper use of the substance in various situations. Linear Formula: C 6 H 5 C 6 H 4 OH. Phenols are common in nature; examples include tyrosine, one of the standard amino acids found in most proteins; epinephrine (adrenaline), a stimulant hormone produced by the adrenal medulla; serotonin, a neurotransmitter in the brain; and urushiol, an irritant secreted by poison ivy to prevent animals from eating its leaves. Phenol itself is the only one of the family that you are likely to need to know about for UK A level purposes. Benzene is easily converted to chlorobenzene by a variety of methods, one of which is the Dow process. Examples include recommended measures on fire-fighting, transport and recycling and disposal. The polymerization of phenol with formaldehyde involves electrophilic aromatic substitution at the ortho and para positions of phenol (probably somewhat randomly), followed by cross-linking of the polymeric chains. The type of uses and classifications may vary between different submissions to ECHA and for a full understanding it is recommended to consult the source data. An oxygen atom normally forms two σ bonds with other atoms; the water molecule, H2O, is the...…, As an example, phenolic pollutants (organic compounds of the types known as phenol, cresol, and resorcinol)...…, >phenols) and the carboxylic acids. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. This information has not been reviewed or verified by ECHA, and may change without prior notice. Unlike simple alcohols, most phenols are completely deprotonated by sodium hydroxide (NaOH). 215–540–4, is covered by three harmonisations: 005–011–00–4; 005–011–01–1 and 005–011–02–9), CLH information cannot be displayed in the InfoCard as the difference between the CLH classifications requires manual interpretation or verification. Abstract. A milder, more general reaction is the diazotization of an arylamine (a derivative of aniline, C6H5NH2) to give a diazonium salt, which hydrolyzes to a phenol. REACH registered substance data was upgraded on 9th November. Other substituted phenols are used in the dye industry to make intensely coloured azo dyes.
