The present invention relates to a process for preparing severely sterically hindered secondary amine ether alcohols and diamine polyalkenyl ethers by reacting a primary amino compound with a polyalkenylether glycol in the presence of a high activity nickel powder hydrogenation catalyst which is marked by high conversion of reactants and increased selectivity to desired final product.

L'invention concerne un procédé de préparation d'éthers alcools d'amines secondaires à encombrement stérique sévère et de diaminopolyalcényléthers en faisant réagir un composé amino primaire avec un polyalcényléther glycol en présence d'un catalyseur d'hydrogénation de poudre de nickel à activité élevée qui est marqué par la conversion élevée de réactifs et une sélectivité accrue du produit final voulu.
