1. A chemical reaction in which a cyanoethyl group (–CH₂CH₂CN) is introduced into a molecule, typically used in organic synthesis and polymer chemistry.
Usage: technical; chemistry

Examples

• Cyanoethylation of cellulose produces a modified polymer with improved properties.
• The chemist performed cyanoethylation on the amine compound to introduce the cyanoethyl substituent.
• Cyanoethylation reactions are commonly catalyzed by bases in organic synthesis.
• The process of cyanoethylation can enhance the solubility of certain polymers.
