Aminomono- or -di-[(poly-n-butoxy)-n-butylamino]-(poly-n-butoxy)-n-butylamines

摘要

Aminomono- or di-[(poly-n-butoxy)-n-butylamino]-(poly-n-butoxy)-n-butylamines of the general formula I H2N-[(CH2CH2CH2CH2O)x-(CH2)4-NH]y-(CH2CH2CH2CH2O)x-(CH2)4-NH2 (I) where x is from 1 to 150 and y is 1 or 2, are prepared by a process in which a hydroxy-(poly-n-butoxy)-butanol of the formula II HO-(CH2CH2CH2CH2O)x-(CH2)4-OH (II) where x is from 1 to 150, is reacted with from 1.01 to 300 mole equivalents of ammonia per hydroxyl group in the presence of a hydrogenation/dehydrogenation catalyst and hydrogen at from 150 DEG to 300 DEG C. and under from 20 to 400 bar.
