Key Properties
Epichlorohydrin (ECH) is a reactive epoxide compound with the molecular formula C₃H₅ClO and CAS No. 106-89-8. It appears as a colorless, volatile liquid with a pungent odor. It has a boiling point of about 116 °C and is slightly soluble in water but miscible with many organic solvents. Due to its epoxy and chlorinated functional groups, ECH is highly reactive and widely used in polymer synthesis.
Key Features
ECH is a key intermediate for producing epoxy resins and glycerol derivatives. It provides excellent reactivity for crosslinking and polymer formation, improving chemical resistance, mechanical strength, and adhesion in end-use materials. It is essential in coatings, adhesives, and composite systems requiring high performance and durability.
Main Applications
Epichlorohydrin is primarily used in the production of epoxy resins for coatings, adhesives, composites, and electronic materials. It is also used to manufacture synthetic glycerin, elastomers, wet-strength resins for paper, ion exchange resins, and water treatment chemicals. In addition, it is used in rubber, textiles, and specialty chemical industries.
Production Process
Epichlorohydrin is mainly produced from propylene via chlorination and epoxidation processes. Modern processes may also use glycerol as a renewable feedstock. The crude product is purified through distillation to obtain high-purity epichlorohydrin suitable for industrial applications.
