What is Diethyl ketone?
Diethyl ketone (CAS 96-22-0), also known as DEK or propione, is a mid-chain ketone solvent.
Where is Diethyl ketone used?
- Pharmaceutical manufacturing: process solvent for active ingredient synthesis and recrystallization steps where controlled evaporation is required
- Flavoring: flavoring agent in food products, contributing to artificial fruit, dairy, and confectionery profiles
- Personal care and cosmetics: carrier solvent for resins, waxes, and film-forming polymers
- Nail care and specialty coatings: solvent in nail care and industrial coating products
- Specialty coatings and inks: alternative to MEK where faster evaporation or different solvency parameters are needed
Good to know: Not to be confused with MEK; DEK is used as an alternative where faster evaporation or different solvency parameters are needed.
Commercial specifications
- Drums and IBC totes; bulk quantities for industrial users
- Technical and high-purity grades
