Abstract
Bis-(N,N-dialkylamino) ethers of the formula (R2NR')2O, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group containing 2 or 3 carbon atoms, are produced by a two-step, "one-pot" reaction that utilises specified molar proportions of SO3 vapour and either R2NR' ONa or R2NR'OK as reactants and is carried out in the presence of R2NR'OH, wherein R and R' are as defined above. The resulting bis-ethers are useful as catalysts in the production of polyurethanes, especially cellular polyurethanes.
