The invention pertains to a process for preparing hydroxyethylethyleneamines, ethyleneamines, or mixtures thereof, and/or ethylene urea derivatives thereof comprising the step of reacting diethanolamine with an amine-functional compound comprising at least two –NH-units of which at least one is selected from the group of primary amine groups and cyclic secondary amine groups, the amine-functional compound comprising at least one –NH-CH2-CH2-NH-unit wherein one or more -NH- CH2-CH2-NH-units in the amine-functional compound may be present in the form of cyclic ethylene urea moieties, piperazine moieties, or linear ethylene urea moieties, in the presence of a carbon oxide delivering agent, wherein -the molar ratio of amine-functional compound to diethanolamine is at least 0.2:1, and -the molar ratio of carbon oxide delivering agent to –NH-CH2-CH2-NH-units in the amine-functional compound is at least 0.1:1. The invention makes it possible to obtain higher hydroxyethylethyleneamines, ethyleneamines, or mixtures thereof, and/or ethylene urea derivatives thereof from diethanolamine, which is an attractive starting material.
该发明涉及一种制备羟乙基乙烯胺、乙烯胺或二者的混合物,和/或其乙烯脲衍生物的过程,包括将二乙醇胺与一种含有至少两个-NH-基团的胺基化合物反应的步骤,其中至少一个选自一次胺基团和环状二次胺基团的组中,该胺基化合物包括至少一个-NH-CH2-CH2-NH-基团,其中该胺基化合物中的一个或多个-NH-CH2-CH2-NH-基团可以以环状乙烯脲基团、哌嗪基团或线性乙烯脲基团的形式存在,存在一种碳氧化物传递剂的情况下,其中-胺基化合物与二乙醇胺的摩尔比至少为0.2:1,和-碳氧化物传递剂与胺基化合物中的-NH-CH2-CH2-NH-基团的摩尔比至少为0.1:1。该发明使得从二乙醇胺中获得更高的羟乙基乙烯胺、乙烯胺或二者的混合物,和/或其乙烯脲衍生物成为可能,而二乙醇胺是一种有吸引力的起始原料。
