Information on phenol (also known as carbolic acid and hydroxybenzene), for responding to chemical incidents. Published 1 July 2014 Phenol is a family of organic compounds that consist of an aromatic ring bonded to an alcohol group. The molecular formula of phenol is C 6 H 5 OH. Its physical properties include a high boiling. Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. The more stable the ion is, the more likely it is to form

Phenol is a corrosive organic compound (technically, a hydrocarbon) in many household cleaners and construction products. It smells sweet and tarry and is usually cloudy in commercial liquid cleansers. In both its natural and synthetic form it's toxic to mammals -- particularly cats, who lack the ability to clean it out of their bloodstream Phenol, molten is the white crystalline solid shipped at an elevated temperature to form a semi-solid. It is very hot and may cause burns from contact and also may cause the ignition of combustible materials. It is toxic by ingestion, and inhalation of its fumes, and skin absorption. It may also be very irritating to skin and eyes Phenol was isolated for the first time from coal tar in 1834. Initially, its disinfecting properties meant that it was used to treat wounds. It was soon discovered that a vast number of useful derivatives could be synthesised from it, preparing the ground for today's high-quality, high-value Phenol derivative products The PHENOL Kickstarter was a success!

Phenol is the simplest aromatic alcohol which characterized by a hydroxyl (-OH) group attached to a benzene ring. The term phenol is not only for phenol itself but also for a class of aromatic compounds possessing a hydroxyl group attached to a benzene ring or a complex ring system. Phenol in water solution is sometimes called carbolic acid Phenol reacts with ethanoyl chloride at room temperature, although the reaction isn't as fast as the one between ethanoyl chloride and an alcohol.

Phenol is a basic feedstock for the production of phenolic resins, bisphenol A, caprolactam, chlorophenols and several alkylphenols and xylenols. Phenol is also used in disinfectants and antiseptics. Occupational exposure to phenol has been reported during its production and use, as well as in the use of phenolic resins in the wood products. Phenol is readily adsorbed through intact skin and is highly toxic to cells. Cellular damage and death at the site of entry results in a chemical burn, which may be extremely serious.
