Phenols. In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (− O H) bonded directly to an aromatic hydrocarbon group. [1] The simplest is phenol, C. 6H. 5OH.
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile . The molecule consists of a phenyl group ( −C 6 H 5 ) bonded to a hydroxy group ( −OH ).
Polyphenols (/ ˌpɒliˈfiːnoʊl, - nɒl /) are a large family of naturally occurring phenols. [ 1 ] They are abundant in plants and structurally diverse. [ 1 ][ 2 ][ 3 ] Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments.
Category:Phenols. Category. : Phenols. Wikimedia Commons has media related to Phenols. Phenols are aromatic compounds with a hydroxyl functional group. The chemistry of the hydroxyl group in this chemical environment is substantially different than those found in alcohols .
The process of maceration or extended skin contact allows the extraction of phenolic compounds from the skins of the grape into the wine. In red wine, up to 90% of the wine's phenolic content falls under the classification of flavonoids. These phenols, mainly derived from the stems, seeds and skins are often leached out of the grape during the ...
Alkylphenol. Alkylphenols are a family of organic compounds obtained by the alkylation of phenols. The term is usually reserved for commercially important propylphenol, butylphenol, amylphenol, heptylphenol, octylphenol, nonylphenol, dodecylphenol and related "long chain alkylphenols" (LCAPs). Methylphenols and ethylphenols are also ...
The mixture of nonylphenol isomers is a pale yellow liquid, although the pure compounds are colorless. The nonylphenols are moderately soluble in water [ 12 ] but soluble in alcohol. Nonylphenol arises from the environmental degradation of nonylphenol ethoxylates , which are the metabolites of commercial detergents called alkylphenol ethoxylates.
