<p>A process is provided for producing bis-(N,N-dialkyl- amino)-alkyl ethers of the formula (R<Sub>2</Sub>NR')<Sub>2</Sub>0, 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, 'one pot' reaction that utilizes a chloro-containing compound selected from the group consisting of sulfuryl chloride, thionyl chloride and chlorosulfonic acid together with R<Sub>2</Sub>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.</p> |
