Coupling reaction of the hydroxy group with epichlorohydrin, followed by dehydrohalogenation The majority of the commercially utilised epoxy monomers are produced by the reaction of a compound with acidic hydroxy groups and epichlorohydrin. To start with a hydroxy group reacts in a very coupling response with epichlorohydrin, accompanied by dehydrohalogenation. https://www.propanraya.com/id/produk/epoxy-fast-dry
