Propenylphenols broadly are compounds containing a propenyl group bonded to a phenol ring. These include many phenylpropanoids, where there are typically other substituents bonded to the aromatic ring. Propenylphenol specifically may refer to the following isomers of C 9 H 10 O (molar mass 134.17 g/mol): Anol (4-propenylphenol) Chavicol (4-(2 ...
In organic chemistry, 1-propenyl (or simply propenyl) ... p-Isopropenylphenol features a 2-propenyl derivative of phenol. Isopropenyl acetate is a 2-propenyl ester, ...
4-Isopropenylphenol is an organic compound with the formula CH 2 =(CH 3)CC 6 H 4 OH.The molecule consists of a 2-propenyl group (CH 2 =C-CH 3) affixed to the 4 position of phenol.The compound is an intermediate in the production of bisphenol A (BPA), 2.7 Mkg/y of which are produced annually (2007).
The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and ...
The ferric chloride test is used to determine the presence of phenols in a given sample or compound (for instance natural phenols in a plant extract). Enols , hydroxamic acids , oximes, and sulfinic acids give positive results as well. [ 1 ]
The long-chain alkylphenols are prepared by alkylation of phenol with alkenes: C 6 H 5 OH + RR'C=CH2 → RR'CH−CH 2 −C 6 H 4 OH. In this way, about 500M kg/y are produced. Alkylphenols ethoxylates are common surfactants. Long-chain alkylphenols are used extensively as precursors to detergents.

To calculate phenol coefficient, the concentration of phenol at which the compound kills the test organism in 10 minutes, but not in 5 minutes, is divided by the concentration of the test compound that kills the organism under the same conditions (or, probably more common, dividing the dilution factor at which the tested substance shows ...
