Description

General description

Chlorobenzene is an aromatic compound that can be used as a solvent, degreasing agent, and chemical intermediate in various industries. It can be synthesized by the chlorination of benzene.

Application

Chlorobenzene can be used as a solvent in the:

• Hydrosilylation of substituted benzaldehydes.
• Knoevenagel condensation of aldehydes and ketones with alkyl nitriles.
