In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, also known as carbolic acid, which he derived in an impure form from coal tar.In August 1865, Joseph Lister applied a piece of lint dipped in carbolic acid solution to the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg.
In female elephants, the two compounds 3-ethyl phenol and 2-ethyl 4,5 dimethylphenol have been detected in urine samples. [70] Temporal glands secretion examination showed the presence of phenol, m-cresol and p-cresol (4-methyl phenol) during musth in male elephants. [71] [72] [73] p-Cresol and o-cresol are also components of the human sweat.
Phenol is reduced to benzene when it is distilled with zinc dust or when its vapour is passed over granules of zinc at 400 °C: [22] C 6 H 5 OH + Zn → C 6 H 6 + ZnO. When phenol is treated with diazomethane in the presence of boron trifluoride (BF 3), anisole is obtained as the main product and nitrogen gas as a byproduct. C 6 H 5 OH + CH 2 N ...

Lifebuoy is a British brand of soap marketed by Unilever.Lifebuoy was originally, and for much of its history, a carbolic soap containing phenol (carbolic acid, a compound extracted from coal tar).
Another method entails methylation of phenol with methanol over a solid acid catalyst, often comprising magnesium oxide or alumina. Temperatures above 300 °C are typical. Anisole converts to cresols under these conditions. [5] [6] Another isomer of cresol is called Benzyl alcohol, or alpha-cresol (α-cresol).
Dettol antiseptic liquid is a product produced by the Dettol Brand for Reckitt.It is light yellow in color in the concentrated form but, as several of the ingredients are insoluble in water, it produces a milky emulsion of oil droplets when diluted with water, exhibiting the ouzo effect.
o-Phenylphenol is often used instead of phenol, since it is somewhat less corrosive. Chloroxylenol is the principal ingredient in Dettol, a household disinfectant and antiseptic. Hexachlorophene is a phenolic that was once used as a germicidal additive to some household products but was banned due to suspected harmful effects.
