DEFINITION

Classification: 549/514

(under subclass 513) Processes which include obtaining a glycidyl moiety by a condensation reaction of an epihalohydrin, (X=halogen) or a glycerol mono- or di-halohydrin, [figure]

(1) Note. The glycidyl moiety is represented by the following basic structure. [figure]
