Process for preparing primary amines which have at least one functional group of the formula (—CH
2
—NH
2
) and at least one further primary amino group by alcohol amination of starting materials having at least one functional group of the formula (—CH
2
—OH) and at least one further functional group (—X), where (—X) is selected from among hydroxyl groups and primary amino groups, by means of ammonia with elimination of water, wherein the reaction is carried out homogeneously catalyzed in the presence of at least one complex catalyst comprising at least one element selected from groups 8, 9 and 10 of the Periodic Table and also at least one donor ligand.
通过醇胺化起始物质制备至少具有一个功能基团(—CH2—NH2)和至少一个进一步的初级氨基基团的初级胺的过程,其中起始物质至少具有一个功能基团(—CH2—OH)和至少一个进一步的功能基团(—X),其中(—X)从羟基和初级氨基中选择,通过氨与水的消除,反应在至少包含来自周期表8、9和10族中选择的至少一个元素以及至少一个给体配体的至少一个复合催化剂的存在下均匀催化进行。
