Overview
Dichloroethyl ether ( CAS 111-44-4 ), also known as Bis(2-chloroethyl)ether or DCEE, is a chlorinated solvent used across industrial manufacturing and chemical processing.
It functions as a selective solvent, biocidal agent, and flame-retardant intermediate in demanding industrial applications. In textile and leather processing, it acts as a solvent for fats and greases.
This chemical enables effective scouring and finishing operations by dissolving resins that resist conventional solvent systems. Plastics and polymer manufacturers use it as a reactive intermediate.
Its chlorine content contributes to fire-suppression performance in finished materials through the synthesis of flame-retardant additives. In printing, it supports ink and coating formulations.
The compound provides aggressive solvent action on difficult substrates for the packaging industry. Its biocidal properties also make it relevant as a preservation agent in industrial fluids.
It is frequently utilized in paper processing treatments where microbial control is required. DCEE is supplied as a liquid in drum and IBC quantities suited to industrial-scale procurement.
It is available primarily in technical grade, reflecting its industrial rather than pharmaceutical or food-related end uses. Buyers should confirm purity specifications and packaging requirements.
Concentrations and inhibitor packages may vary by source, so direct consultation with suppliers is recommended. This ensures the material meets the specific needs of your manufacturing process.
