Process for preparing cyclic N-vinylacylamines |
摘要 |
Cyclic N-vinylacylamines are prepared by heating carbonic acid esters of cyclic N-2-hydroxyethylacylamines in the presence of a catalytic amount of alkali or alkaline earth metal compound having an alkaline reaction and subsequently distilling the reaction mixture. Cyclic N-vinylacylamines are valuable precursors for preparing plant protection agents and medicaments and serve as polymerization and copolymerization components for preparing plastics, surface coatings, paints and ion exchange materials.
