Description

General description

Propionyl chloride is an important chemical intermediate used to synthesize various propionic acid derivatives.

Application

Propionyl chloride can be used as an acylating agent:

To convert anisole to 4-methoxypropiophenone and 2-methoxynaphthalene to 1-propio-2-methoxynaphthalene in the presence of Indium(III) chloride (InCl₃) impregnated mesoporous Si-MCM-41 catalyst.

It can also be used:

For chlorination in the presence of sulfuryl chloride and peroxides to form α-chloropropionyl chloride and β-chloropropionyl chloride.
In reaction with (hydroxypropyl)cellulose to form the propanoate ester, [(propionyloxy)propyl]cellulose.
