What is Dichloroethyl ether?
Dichloroethyl ether (CAS 111-44-4), also known as Bis(2-chloroethyl)ether or DCEE, is a chlorinated solvent used in industrial manufacturing and chemical processing.
Where is Dichloroethyl ether used?
- Textile and leather processing: solvent for fats and greases
- Printing: support for ink and coating formulations
- Packaging: aggressive solvent action on difficult substrates
- Plastics and polymer manufacturing: reactive intermediate
- Industrial fluids: preservation agent
- Paper processing: treatments requiring microbial control
- It enables scouring and finishing by dissolving resins that resist conventional solvent systems.
Good to know: Concentrations and inhibitor packages may vary by source; consult suppliers directly. Buyers should confirm purity specifications and packaging requirements.
