| 摘要 |
Bis-(N,N-dialkylamino)alkyl ethers are produced by reacting a (N,N-dialkylamino) alkanol over a heterogeneous solid acid catalyst. The (N,N-dialkylamino) alkanol can optionally be accompanied by an inert carrier. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes. |
