摘要：
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 NH 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.
