Epichlorohydrin (ECH), scientifically known as chloromethyloxirane and identified by CAS number 106-89-8, is a fascinating and industrially significant organic chemical. Its unique molecular structure, featuring both an epoxide ring and a chloromethyl group, imbues it with high reactivity, making it a versatile building block in chemical synthesis. Understanding its properties and synthesis is key for anyone involved in its purchase or application.

Physically, Epichlorohydrin is a colorless, volatile liquid with a sharp, chloroform-like or garlic-like odor. Its properties include a relatively low boiling point of approximately 117.9 °C and a significant solubility in water, though it is miscible with most organic solvents. These characteristics influence its handling, storage, and application in various industrial processes. Its density is approximately 1.1812 g/cm³.

The synthesis of Epichlorohydrin typically begins with propylene, which is chlorinated to produce allyl chloride. This allyl chloride is then reacted with hypochlorous acid to form glycerol dichlorohydrin, which is subsequently dehydrochlorinated with a base, such as calcium hydroxide or sodium hydroxide, to yield Epichlorohydrin. This established manufacturing route ensures its availability as an industrial chemical raw material.

The industrial significance of ECH cannot be overstated. Its primary role is as a monomer for the production of epoxy resins, which are foundational materials for adhesives, coatings, electrical laminates, and structural components across numerous industries. Furthermore, ECH is a crucial intermediate in the production of synthetic glycerol, a compound vital for pharmaceuticals, cosmetics, and the food industry.

Other applications include its use in the manufacture of synthetic rubber, ion-exchange resins, water treatment chemicals, and as a solvent for various natural and synthetic resins. For businesses requiring this versatile compound, sourcing from reputable Epichlorohydrin manufacturers ensures access to a high-quality organic intermediate that fuels innovation and production across the chemical landscape.
