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.
Claims14
A process for the production of sterically hindered amino ether alcohols, diaminopolyalkenyl ethers, and mixtures thereof, comprising reacting an alkyl substituted primary amino compound with a polyalkenyl ether glycol, over a catalyst comprising a catalytically active metal, but excluding platinum and palladium, on a support, the support characterized by a micropore volume above about 0.5 cm3/g, the metal loaded catalyst exhibiting a pore size distribution when normalized for pore of 19.99 nm or less of about 30% or more of pores of up to 4.99 nm, the pores of 5 to up to 19.99 nm constituting the balance.
