Abstract
A process for preparing aminoethers, particularly bis[2-(N,N-dialkylamino)alkyl]ethers, which comprises contacting a carboxylated aminoether with a metal oxide catalyst under conditions effective to produce the aminoether. Many of these aminoethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes.
