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.
环状N-乙烯基酰胺是通过在碱性或碱土金属化合物的催化下加热环状N-2-羟乙基酰胺的碳酸酯制备的,随后蒸馏反应混合物。环状N-乙烯基酰胺是制备植物保护剂和药物的有价值的前体,并作为聚合和共聚合组分,用于制备塑料、表面涂料、油漆和离子交换材料。
