This substance is used in the following areas: formulation of mixtures and/or re-packaging and building & construction work. 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). Lignin is a good candidate to replace phenol in the phenol formaldehyde resins’ formulation because (a) its polyphenolic structure is similar to that of phenolic resin (Fig. In 1865 the British surgeon Joseph Lister used phenol as an antiseptic to sterilize his operating field. 2-Propenoic acid, polymer with 4-(1,1-dimethylethyl)phenol, formaldehyde, 2,5-furandione, 2-methyloxirane, 4-nonylphenol and oxirane Valid Active Substances for which classification and labelling data have been notified to ECHA by manufacturers or importers. 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. 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. For example, the systematic name for vanillin is 4-hydroxy-3-methoxybenzaldehyde. This website uses cookies to ensure you get the best experience on our websites. 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. Public (risk management) activities co-ordination table. More information about CAS and the CAS registry can be found here. Individual Protection Measures, Such as Personal Protective Equipment The source of the information is mentioned in the introductory sentence of the hazard statements. If at least one company has indicated that the substance classification is affected by impurities or additives, this will be indicated by an informative sentence. 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. This stabilization is most effective for attack at the ortho or para position of the ring; therefore, the hydroxyl group of a phenol is considered to be activating (i.e., its presence causes the aromatic ring to be more reactive than benzene) and ortho- or para-directing. The simplest way to draw the structure of phenol is: When information is available in all sources, the first two are displayed as a priority. Many phenolic compounds were discovered and used long before chemists were able to determine their structures. 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 EC Inventory is a combination of three independent European lists of substances from the previous EU chemicals regulatory frameworks (EINECS, ELINCS and the NLP-list). This reaction is used commercially to make salicylic acid for conversion to aspirin and methyl salicylate. Phenols are widely used in household products and as intermediates for industrial synthesis. Data sources include IBM Watson Micromedex (updated 7 Dec 2020), Cerner Multum™ (updated 4 Dec 2020), ASHP (updated 3 Dec … Commercial materials are most commonly based on phenol itself; other phenols such as cresols, xylenols and resorcinol are used to a limited extent. Impurities or additives: When a specific critical property is calculated from industry data and where the majority of data submitters have indicated that the property relates to cases containing impurities and/or additives, then the respective critical property icon is modified with an asterisk (*). Furthermore, some substances can be found in an article, but with unlikely exposure (e.g. Phenol may have been the first surgical antiseptic. Hydrogen bonding results in higher melting points and much higher boiling points for phenols than for hydrocarbons with similar molecular weights. For example, chromic acid oxidizes most phenols to conjugated 1,4-diketones called quinones. For readability purpose, only non-confidential use descriptors occurring in more than 5% of total occurrences are displayed. 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 EC or list number is the primary substance identifier used by ECHA. For example, phenol (molecular weight [MW] 94, boiling point [bp] 182 °C [359.6 °F]) has a boiling point more than 70 degrees higher than that of toluene (C6H5CH3; MW 92, bp 111 °C [231.8 °F]). The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format. The Prior Informed Consent Regulation administers the import and export of certain hazardous chemicals and places obligations on companies who wish to export these chemicals to non-EU countries. BPR regulation aims to improve the functioning of the biocidal products market in the EU, while ensuring a high level of protection for humans and the environment. Tool showing an overview of substances in various key regulatory processes that authorities are working on. The most obvious difference is the enhanced acidity of phenols. REACH regulation aims to improve the protection of human health and the environment from the risks that can be posed by chemicals. Nhận dạng; Số CAS: Trừ khi có ghi chú khác, dữ liệu được cung cấp cho các vật liệu trong trạng thái tiêu chuẩn của chúng (ở 25 °C [77 °F], 100 kPa). Unexposed grains of silver bromide react more slowly than the exposed grains.

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. A prioritisation hierarchy means that data is taken from harmonised C&L data and regulatory lists first, then REACH registrations and finally from CLP notifications. In the presence of oxygen in the air, many phenols slowly oxidize to give dark mixtures containing quinones. ECHA has no public registered data on the routes by which this substance is most likely to be released to the environment. Amines, tallow alkyl, reaction products with formaldehyde and phenol, ethoxylated Unknown: TSCA Inv Amines, tallow alkyl, reaction products with formaldehyde and phenol, ethoxylated Valid: Inactive 2020 CDR Full Exempt Amines, tallow alkyl, reaction products with formaldehyde and phenol… Drugs.com provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. This information is only displayed if the substance is well–defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure. The common phenol hydroquinone is the component of photographic developer that reduces exposed silver bromide crystals to black metallic silver. 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. These notifications can be provided by manufacturers, importers and downstream users. For example, the systematic name for thymol is 5-methyl-2-isopropylphenol. An effective explosive needs a high proportion of oxidizing groups such as nitro groups. Systematic names are more useful, however, because a systematic name specifies the actual structure of the compound. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. Such notifications are required for hazardous substances, mixtures, or articles, manufactured or imported at over 1 kg per annum. Formaldehyde reacts with ammonia forms formamidine and water. Although phenols are often considered simply as aromatic alcohols, they do have somewhat different properties. For example, phenols react with acids to give esters, and phenoxide ions (ArO−) can be good nucleophiles in Williamson ether synthesis. For example, vanillin, the principal flavouring in vanilla, is isolated from vanilla beans, and methyl salicylate, which has a characteristic minty taste and odour, is isolated from wintergreen. Abstract. The ability of phenols to form strong hydrogen bonds also enhances their solubility in water. The substance identifiers displayed in the InfoCard are the best available substance name, EC number, CAS number and/or the molecular and structural formulas. 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.. 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. Professor of Chemistry, Whitman College, Walla Walla, Washington. Updates? Most of the phenol used today is produced from benzene, through either hydrolysis of chlorobenzene or oxidation of isopropylbenzene (cumene). the electronic edition of the Official Journal of the European Union. Although this process seems more complicated than the Dow process, it is advantageous because it produces two valuable industrial products: phenol and acetone. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. Close Find out more on how we use cookies. To make more-complicated phenolic compounds, a more general synthesis is needed. This section is based on three sources for information (harmonised classification and labelling (CLH), REACH registrations and CLP notifications). Examples include recommended measures on fire-fighting, transport and recycling and disposal. This section provides an overview of the calculated volume at which the substance is manufactured or imported to the European Economic Area (EU28 + Iceland, Liechtenstein and Norway). Details of dossier compliance checks and testing proposal evaluation. Release to the environment of this substance can occur from industrial use: in the production of articles. 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. Chlorobenzene is hydrolyzed by a strong base at high temperatures to give a phenoxide salt, which is acidified to phenol. This substance is used in the following areas: building & construction work. 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. In this study, three different boron compounds were used together with alkaline catalyst to synthesize phenol formaldehyde (PF) resole resins in situ. … 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. More information about the EC Inventory can be found here. CAS Number: 92-69-3 They are formed through the reaction of phenol with formaldehyde, followed by cross-linking of the polymeric chains.

Phenolic resins account for a large portion of phenol production. This substance is used for the manufacture of: plastic products, mineral products (e.g. 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. The ‘Substance identity’ section is calculated from substance identification information from all ECHA databases. Nitro groups are strongly deactivating (i.e., make the aromatic ring less reactive), however, and it is often difficult to add a second or third nitro group to an aromatic compound. Occupational exposure limit (OEL) values are derived within two legal frameworks that form an integral part of the EU’s mechanism for protecting the health of workers.
