What is the function of epichlorohydrin?


Epichlorohydrin (ECH) is a halfway substance used to create epoxy gums (around 90% of the worldwide market), engineered glycerin, epichlorohydrin elastomers, specialty synthetic compounds for water treatment, wet strength pitches for paper creation, and surfactants.

Is epichlorohydrin volatile?


Epichlorohydrin is a volatile, highly reactive, and unstable epoxide compound. Epoxy resins are typically made by combining epichlorohydrin and bisphenol A.

What PPE is needed when using epichlorohydrin?


Any respirator that uses supplied air and has a full facepiece, helmet, or hood. Any breathing device that can be used alone and has a complete facepiece. An Independent breathing device with a full facepiece worked in the tension interest or another positive strain mode.

What does epichlorohydrin react with?


Glycidyl nitrate and alkali chloride are produced when an alkali nitrate, such as sodium nitrate, reacts with the epichlorohydrin. It is used as an insect fumigant and a cellulose, resin and paint solvent.

Is epichlorohydrin biodegradable?


Since the body quickly breaks down epichlorohydrin, it is unlikely to remain in the environment. Epichlorohydrin is unlikely to adsorb to soil or sediment and has a low bioaccumulation potential.

Does epichlorohydrin react with water?


Monochloropropanediol (MCPD) is produced when epichlorohydrin (EPI) reacts with water under the action of aqueous acid. On heating, this mixture of the post-hydrolysis reaction can polymerize and eventually decompose.

How do you handle epichlorohydrin?


Epichlorohydrin is a flammable and reactive liquid that can polymerize violently. It is also combustible. As extinguishing agents, make use of dry chemicals, CO2, water spray, or alcohol-resistant foam.
