Abstract
A process for producing bis-(N,N- dialkylamino)-alkyl ether having the formula (R2NR')2O, wherein R is a methyl or ethyl group and R' is a bivalent alkylene group containing from 2 to 3 carbon atoms, comprises: (a) reacting sodio N,N- dialkylaminoalkoxide of the formula R2NR'ONa, wherein R and R' are as defined above, with from 0.25 to 0.60 moles of SO3 vapor per mole of sodio N,N-dialkylaminoalkoxide at a temperature of from 20 DEG C to 90 DEG C in the presence of: (I) an organic diluent/dispersant in an amount ranging from 0 to 60 weight percent based on the amount of sodio N,N-dialkylaminoalkoxide and N,N- dialkylaminoalkanol employed, and (II) an N,N-dialkylaminoalkanol of the formula R2NR'OH, wherein R and R' are as defined above, that is present in an amount such that the molar ratio of sodio N,N-dialkylaminoalkoxide to N,N- diaikylaminoalkanol ranges from 1:1 to 1:3 to produce an intermediate reaction product mixture, (b) heating the intermediate reaction product mixture from step (a) to an elevated temperature and maintaining the elevated temperature for a time period sufficient to produce bis (N,N- dialkylamino) alkyl ether. The compounds are catalyst for making polyurethanes.
