Abstract:
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.
