N-Vinyl-N-alkyl-carbamic acid chlorides are manufactured by reacting crude Schiff bases, which have advantageously been manufactured in the presence of pentane, with phosgene and tertiary amines, treating the reaction mixture with water and then isolating the end product, after having separated off the aqueous phase containing the amine salt. The products are starting materials for the manufacture of surface-coating intermediates, plastics, paints and crop protection agents.
N-乙烯基-N-烷基-氨基甲酸氯化物是通过将原始席夫碱与光气和三级胺反应制成的,有利的是在戊烷存在下制成,然后用水处理反应混合物,分离含胺盐的水相后分离出最终产物。该产品是表面涂层中间体,塑料,涂料和农药的制造原料。
