| Zusammenfassung: | The invention relates to a preparation method of a vinyl sulfone hardener, which comprises the steps of amidation reaction, thioether synthesis, oxidation reaction, chlorination reaction and dehydrochlorination reaction. By adopting the technical step of chlorination after oxidation and adjusting the technical conditions, the method avoids the possibility of explosion in the reaction process, shortens the reaction period, lowers the energy consumption and enhances the yield. |
