Pentanol, also known as n-pentanol, 1-pentanol or pentan-1-ol, is a higher chain alcohol, used in the manufacturing of various pleasant smelling esters. It has the chemical formula C5H12O or C5H11OH.

Properties

Chemical

Pentanol can be oxidized to pentanoic acid.

Physical

Pentanol is a colorless liquid, slightly soluble in water.

Availability

Amyl alcohol is sold by various chemical suppliers.

Pentanol can be obtained from the fractional distillation of fusel oil.

Preparation

n-Pentanol is cheaper to buy than synthesize it yourself.

Projects

  • Make esters

Handling

Safety

Like most higher-chain alcohols, n-pentanol has a high flash point, meaning it has low flammability.

Storage

In closed bottles.

Disposal

Can be safely destroyed by mixing it with a more flammable solvent and burned.
