Abstract
An improved process for the production of bis (N,N-dialkylaminoalkyl)ether having the formula (R.sub.2 NR').sub.2 O, wherein R is methyl or ethyl and R' is ethyl or propyl, by reacting vaporized N,N-dialkylaminoalkanol of the formula R.sub.2 NR'OH, wherein R and R' are as defined above, in the presence of a heterogeneous solid basic catalyst. The bis (N,N-dialkylaminoalkyl)ether compounds, especially bis (N,N-dimethylamino)ethyl ether, are useful in the production of polyurethane foams.
Claims12
A process for producing bis (N,N-dialkylamino)alkyl ether having the formula, (R.sub.2 NR').sub.2 O
- wherein R is methyl or ethyl and R' is ethyl or propyl, comprising reacting vaporized N, N-dialkylaminoalkanol of the formula,
- R.sub.2 NR'OH,
- wherein R and R' are as defined above, at elevated temperature in the presence of a heterogeneous solid basic catalyst to form the bis (N,N-dialkylamino)alkyl ether, and recovering the bis (N,N-dialkylamino)alkyl ether.
A process for producing bis (N,N-dimethylamino)ethyl ether comprising reacting vaporized N,N-dimethylaminoethanol at elevated temperature over a heterogeneous solid basic catalyst to form the bis (N,N-dimethylamino)ethyl ether, and recovering the bis (N,N-dimethylamino)ethyl ether.
