Abstract

Abstract Translated from German Cyclische N-Vinylacylamine werden hergestellt durch Erhitzen von Kohlensäureestern cyclischer N-2-Hydroxyethyl-acylamine in Gegenwart katalytischer Mengen alkalisch reagierender Verbindungen von Alkali- oder Erdalkalimetallen und anschließender Destillation des Reaktionsgemisches. Cyclic N-vinyl acylamines are prepared by heating carbonic acid esters of cyclic N-2-hydroxyethyl acylamines in the presence of catalytic amounts of alkaline compounds of alkali or alkaline earth metals and subsequent distillation of the reaction mixture. Die cyclischen N-Vinylacylamine sind wertvolle Vorprodukte zur Herstellung von Pflanzenschutzmitteln und von Arzneimitteln und dienen als Polymerisations-und Copolymerisationskomponenten zur Herstellung von Kunststoffen, Überzügen, Lacken und Ionenaustauschern. The cyclic N-vinylacylamines are valuable precursors for the production of crop protection agents and pharmaceuticals and serve as polymerization and copolymerization components for the production of plastics, coatings, paints and ion exchangers.
