Other Names:


Butyl alcohol


General Information:


CAS Number: 71-36-3

Molecular Weight: 74.12 g/mol

Appearance: Colorless liquid

Melting Point: -90 C

Boiling Point: 116-118 C

n-Butanol is sometimes a useful substitute as a solvent for ethanol or isopropanol because of its higher boiling point (118 C).

Common Uses:

Solvent for reactions

Procedure excerpt:

A mixture of the aryl chloride (A) (1 Kg, 7.72 mol), the amine (B) (1.5 Kg, 10.03 mol), TEA (3.23 L, 23.2 mol), and n-BuOH (8 L) were stirred at reflux . . .
