A process is described for the preparation of oxamide derivatives wherein one or both --NH.sub.2 groups are replaced by primary or secondary amino groups, through reaction of oxamide with a suitably selected amine of formula RR.sup.1 NH wherein R represents a substituted straight or branched (C.sub.2 -C.sub.12)alkyl radical wherein the substituent(s) or at least one of the substituents is selected from the group consisting of hydroxy, amino, mono-substituted amino, and di-substituted amino, and R.sup.1 represents hydrogen or an optionally substituted (C.sub.1 -C.sub.6)alkyl radical; representative oxamide derivatives which can thus be obtained useful as corrosion inhibitors, intermediates for polymers, polymer stabilizers, and slow-release fertilizers, are also described.
本文描述了一种制备氧化酰胺衍生物的过程,其中一个或两个-NH.sub.2基团被一种适当选择的公式RR.sup.1 NH的一级或二级氨基取代,通过氧化酰胺与适当选择的胺反应,其中R代表取代的直链或支链(C.sub.2-C.sub.12)烷基基团,其中取代基或至少一个取代基选自羟基,氨基,单取代氨基和二取代氨基的群;还描述了可以获得的代表性氧化酰胺衍生物,其可用作腐蚀抑制剂,聚合物中间体,聚合物稳定剂和缓释肥料。
