Oceleni řeseui is the suppression of the formation of undesirable byproducts and hence the higher yield of the main silage in the production of multi-functional epoxy resins and the base of polyglycidyl compounds derived from aromatic polyominines with at least two aromatic cycles linked by a methylene bridge. The preparation of these resins involves, in the first phase, the addition of epichlorohydrin or its derivatives to the aromatic monoate and ultimately the dehydrochlorination of chlorohydrins by the action of the cleavage, wherein the chlorohydrides formed by the addition of said servants in the first stage are subjected to acid-catalyzed condensation with formaldehyde and parc-formaldehyde to form poly-N, N-chlorochlorines of aromatic polysmines, which are ultimately dehydrochlorinated by the aforementioned known method. |
