CA 2051573

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.

Procédé pour préparer des aminoéthers, particulièrement des éthers bis[2-(N,N-dialkylamino)alkyliques, qui comprend la mise en contact d'un aminoéther carboxylé avec un catalyseur à base d'oxyde métallique dans des conditions favorables à la production d'un aminoéther. Bon nombre de ces aminoéthers sont utiles comme catalyseurs dans la production de polyuréthanes, et particulièrement de polyuréthanes alvéolaires.
