Phenol, also known under an older name of carbolic acid, is a colorless crystalline solid with a typical sweet tarry odor. Its chemical formula is C6H5OH and its structure is that of a hydroxyl group (-OH) bonded to a phenyl ring; it is thus an aromatic compound.


Phenols
Main article: phenols
The word phenol is also used to refer to any compound which contains a six-membered aromatic ring, bonded directly to a hydroxyl group (-OH). In effect, phenols are a class of organic compounds of which the phenol discussed in this article is the simplest member.


Properties
Phenol has a limited solubility in water (8.3 g/100 ml), but is completely miscible above 40 °C, as a liquid. It is slightly acidic: the phenol molecule has weak tendencies to lose the H+ ion from the hydroxyl group, resulting in the highly water-soluble phenolate anion C6H5O−. Compared to aliphatic alcohols, phenol shows much higher acidity. This is due primarily to inductive effects, contrary to popular belief that mesomeric effects play a significant role.[citation needed]


Production
Phenol can be made from the partial oxidation of benzene, by the cumene process, or by the Raschig process. It can also be found as a product of coal oxidation.


Uses
Phenol has antiseptic properties, and was used by Sir Joseph Lister in his pioneering technique of antiseptic surgery, though the skin irritation caused by continual exposure to phenol eventually led to the substitution of aseptic (germ-free) techniques in surgery. It is one of the main components of the commercial antiseptic TCP.

Phenol has anesthetic properties, and is the active ingredient in some oral anesthetics such as Chloraseptic spray.

It is also used in the production of drugs (it is the starting material in the industrial production of aspirin), weedkillers, and synthetic resins (Bakelite, one of the first synthetic resins to be manufactured, is a polymer of phenol with formaldehyde). Exposure of the skin to concentrated phenol solutions causes chemical burns which may be severe; in laboratories where it is used, it is usually recommended that polyethylene glycol solution is kept available for washing off splashes. Washing with large amounts of plain water (most labs have a safety shower or eye-wash) and removal of contaminated clothing are required, and immediate ER treatment for large splashes; particularly if the phenol is mixed with chloroform (a commonly used mixture in molecular biology for DNA purification). Notwithstanding the effects of concentrated solutions, it is also used in cosmetic surgery as an exfoliant, to remove layers of dead skin.

Injections of phenol have occasionally been used as a means of rapid execution.

Phenol Uses

Answer 3

phenol is an organic compound with hydroxyl group connected to a benzene ring.

Phenol has anesthetic properties, and is the active ingredient in some oral anesthetics such as Chloraseptic spray.

It is also used in the production of drugs (it is the starting material in the industrial production of aspirin), weedkillers, and explosives. During WWI, the American subsidiary of the Bayer Company bought as much phenol as it could from the international market, knowing that eventually all the phenol could be convered into aspirin. This left little phenol available for the synthesis of 2,4,6-trinitrophenol (TNT), a common explosive.

Answer 4

Phenol is an organic compound that is composed of a benzene ring with one of the hydrogens replaced by an OH or hydroxyl group. It is mostly useful as a solvent, I believe, but it could be used as a fuel or as raw material for making more complex molecules. I also believe it has been used as an antiseptic to kill germs also.

Answer 5

Phenol is an organic compound made of 6 carbons in a ring with an OH or hydroxyl group off the ring. Formula C6H5OH. It has a sweet odor and is irritating to skin eyes and mucous membranes.

Answer 6

phenol is the compound of alcohols in organic chemistry and is associated with benzene rings
it is used to make bakelite plastics

Answer 7

Just one correction...TNT is not a phenol analog. TNT is trinitrotoluene. Toluene has a methyl group, where phenol has a hydroxy group attached to a benzene ring.

Answer 8

it's an organic compound with aromatic qualities from the benzene, and an alcohol group. It's typically a solvent.

Answer 9

it can be a lot of things one thing is a shell.
