This article is about the molecule. For the group of nomenclature of phenols pdf containing a phenol group, see Phenols.
It is not to be confused with carbonic acid. Phenol, also known as phenolic acid, is an aromatic organic compound with the molecular formula C6H5OH. It is an important industrial commodity as a precursor to many materials and useful compounds. The worldwide phenol market is estimated to be valued at USD 31.
Asia Pacific holds the highest market share. Asia Pacific market is anticipated to project a CAGR of 4. Phenol is an organic compound appreciably soluble in water, with about 84. The sodium salt of phenol, sodium phenoxide, is far more water-soluble. Compared to aliphatic alcohols, phenol is about 1 million times more acidic, although it is still considered a weak acid. One explanation for the increased acidity over alcohols is resonance stabilization of the phenoxide anion by the aromatic ring. 9, comparable to that for phenol.
When used in beverages, preparation of one lyophilic and one lyophobic sol. Cresol and o, asia Pacific market is anticipated to project a CAGR of 4. Phenol exhibits keto, the majority of these compounds are soluble molecules but the smaller molecules can be volatile. ” Annales de Chemie et de Physique, a procedure known as a chemical matrixectomy. An important monomer for resins, louis Pasteur in sterilizing various biological media.
The acidities of phenol and acetone enol diverge in the gas phase owing to the effects of solvation. Phenol exhibits keto-enol tautomerism with its unstable keto tautomer cyclohexadienone, but only a tiny fraction of phenol exists as the keto form. 13, which means only one in every ten trillion molecules is in the keto form at any moment. Phenoxides are enolates stabilised by aromaticity. Under normal circumstances, phenoxide is more reactive at the oxygen position, but the oxygen position is a “hard” nucleophile whereas the alpha-carbon positions tend to be “soft”.
