This is why novolacs (F:P <1) do not harden without the addition of a crosslinking agents, and why resoles with the formula F:P >1 will. 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. A majority of data submitters agree this substance is Skin sensitising. Phenol, the cresols (methylphenols), and other simple alkylated phenols can be obtained from the distillation of coal tar or crude petroleum. The association between water and phenol is unusually strong; when crystalline phenol is left out in a humid environment, it picks up enough water from the air to form liquid droplets. Synonyms. When the molar ratio of formaldehyde:phenol reaches one, in theory every phenol is linked together via methylene bridges, generating one single molecule, and the system is entirely crosslinked. 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. Professor of Chemistry, Whitman College, Walla Walla, Washington. 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. Other substituted phenols are used in the dye industry to make intensely coloured azo dyes. Phenolic resins are a group of the most versatile polymers yet invented. The described Product category (i.e. Systematic names are more useful, however, because a systematic name specifies the actual structure of the compound. Catalyst levels range from 0.5% to 3%. Prepolymer resol resins with different phenol/formaldehyde/NaOH molar ratios were synthesized and characterized by technical analysis as well as by C-13 NMR spectra for samples in CD3OD solution. The EC Number is the numerical identifier for substances in the EC Inventory. The molecular structure is based on structures generated from information available in ECHA’s databases. Phenol-formaldehyde resin. Typically novolaks are prepared by the condensation of a … Therefore, trivial names (i.e., vanillin, salicylic acid, pyrocatechol, resorcinol, cresol, hydroquinone, and eugenol) are often used for the most common phenolic compounds.

Formaldehyde is made of methanol and phenol from benzene using the cumene process. 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. 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). ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. Examples include recommended measures on fire-fighting, transport and recycling and disposal. What is the Classification and Labelling Inventory? 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. Hazard statements were adapted to improve readability and may not correspond textually to the hazard statements codes description in the European Union Specific Hazard Statements (EUH) or the. Typical mole ratios of formaldehyde to phenol range from 1.2 to 1.9 mol of formaldehyde per mol of phenol. The POPs Regulation bans or severely restricts the production and use of persistent organic pollutants in the European Union. The InfoCard summarises the non-confidential data of a substance held in the databases of the European Chemicals Agency (ECHA). Phenol is the simplest member of a family of compounds in which an -OH group is attached directly to a benzene ring. Formaldehyde is an organic compound with the formula CH2O or HCHO and is one of the most important building blocks in the chemical industry. The EC or list number is the primary substance identifier used by ECHA. plasters, cement), fabricated metal products, electrical, electronic and optical equipment and machinery and vehicles. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. [provided by RefSeq, Oct 2008] 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. Besides serving as the generic name for the entire family, the term phenol is also the specific name for its simplest member, monohydroxybenzene (C 6 H 5 OH), also known as benzenol, or carbolic acid. The cumene hydroperoxide reaction is fairly specific to phenol itself. Phenol-formaldehyde resins are heat-resistant and waterproof, though somewhat brittle.
