12,133 NEW PROCESS FOR PREPARING BIS(N,N-DIALKYLAMINO)ALKYL ETHERS ABSTRACT OF THE DISCLOSURE A process is provided for producing bis-(N,N- dialkylamino)alkyl ethers of the formula (R2NR')2O, 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 con- sisting of sulfuryl chloride, thionyl chloride and chloro- sulfonic acid together with R2NR'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. S P E C I F I C A T I O N
