Abstract
A process is provided for producing bis-(N,N-dialkylamino)alkyl ethers of the formula (R.sub.2 NR').sub.2 O, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group having from 2 to 3 carbon atoms. The novel process is effected by a two-step, preferably 'one pot,' reaction that utilizes SO.sub.3 vapor and R.sub.2 NR'ONa as reactants, wherein R and R' are defined above. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes.
