WebIn the process for producing epichlorohydrin according to the invention, the reaction is generally carried out at a temperature of at most 140° C. It is preferably at most 120° C. In a first particular variant, the temperature is from 25 to 50° C. In a second particular variant, the temperature is from 60 to 100° C. WebEpichlorohydrin (ECH), 1-chloro-2,3-epoxypropane, is a raw material used in the production of epoxy resins, synthetic glycerol, elastomers, paper, and pharmaceuticals [1-2]. ECH can enter drinking water supplies by leaching from epoxy resin coatings on pipes or through flocculating agents in water treatment.
