The invention relates to a process for the synthesis of N-substituted cyclic alkylene ureas by reacting a multifunctional aliphatic amine A having at least two amino groups which may be primary or secondary, at least one of which is a primary amino group, -NH2, and at least one of which is a secondary amino group, >NH, the other hydrogen group whereof having been substituted by a hydrocarbyl group which in turn may be substituted by a hydroxyl group, or an amino group, or a carboxyl group, or a ketone carbonyl group, or a hydrazide or hydrazone group, or a mercaptan group, and at least one further functional group selected from the group consisting of primary or secondary amino groups and hydroxyl groups, and an aliphatic organic carbonate component C selected from the group consisting of dialkyl carbonates CD and of alkylene carbonates CA.
本发明涉及一种合成N-取代环状烷基
脲的方法,该方法通过反应一种具有至少两个
氨基的多功能
脂肪族胺A来实现,其中至少一个是一级
氨基-NH2,至少一个是二级
氨基->NH,其它
氢原子被烃基取代,该烃基又可以被羟基、
氨基、羧基、
酮羰基、
肼或
肼酮基、巯基取代,同时还包括至少一种来自于一级或二级
氨基与羟基的功能基团,以及一种来自于
脂肪族有机
碳酸酯组分C的反应,该组分C选自双烷基
碳酸酯CD和烷基
碳酸酯CA的组合。
