Epichlorohydrin
CAS Number: 106-89-8
Epichlorohydrin (ECH) is the key monomer for epoxy resin synthesis, reacting with bisphenol A to produce diglycidyl ether of BPA (DGEBA). It is also used in the production of polyamidoamine-epichlorohydrin (PAE) wet-strength resins, synthetic glycerol, and epoxy flame retardants. Bio-based ECH from glycerol is increasingly available as a renewable alternative.
Technical Specifications

Applications
- DGEBA epoxy resin synthesis from bisphenol A
- PAE wet-strength resin for paper and tissue manufacturing
- Synthetic glycerol and glycidyl compound production
- Epoxy flame retardant synthesis
- Ion-exchange resin functionalization
Key Features
- Low hydrolyzable chlorine is critical for high-purity epoxy resin with minimal ionic impurity
- Ultra-low water content prevents premature ring-opening during epoxy synthesis
- Bio-based grade from glycerol available for sustainable epoxy resin production
- Tightly controlled acidity prevents catalyst deactivation in BPA epoxidation
