Pentanol

Pentanol (also known as amyl alcohol) is a group of compounds with the formula C5H11OH. It is a colorless liquid with an odor that is "alcoholic" to some people. It is used in the manufacture of pharmaceuticals, in the preparation of perfumes, and as a solvent for resins.

Structure and properties

Pentanol has five isomers. All are alcohols with a molecular formula of C5H12O or C5H11OH. The isomers are:

• 1-Pentanol
• 2-Pentanol
• 3-Pentanol
• 2-Methylbutan-1-ol
• 3-Methylbutan-1-ol

Production

Pentanol can be prepared by the acid-catalyzed addition of water to 1-pentene, a reaction that also produces 2-pentanol. Alternatively, it can be produced by the hydroformylation of butene to form butyraldehyde, which is then reduced to pentanol.

Uses

Pentanol is used in the manufacture of pharmaceuticals, in the preparation of perfumes, and as a solvent for resins. It is also used as a flavoring agent in food products.

Safety

Pentanol is a flammable liquid. It can cause irritation to the eyes, skin, and respiratory tract. It can also cause dizziness, headache, and nausea.
