Patent ID: 8921602

Claim:
A method for synthesizing bis[3-(N,N-dialkylamino)propyl]ethers from acrylonitrile, comprising the following reactions: first addition reaction of a water molecule and an acrylonitrile molecule to produce 3-hydroxypropionitrile (reaction 1), second addition reaction of a 3-hydroxypropionitrile molecule obtained by reaction 1 and an acrylonitrile molecule to produce bis(2-cyanoethyl)ether (reaction 2), hydrogenation reaction of the bis(2-cyanoethyl)ether to conduct a reduction of the nitrile functions to primary amine functions in order to produce bis(3-aminopropyl)ether (reaction 3), aminoalkylation reaction of the bis(3-aminopropyl)ether to produce bis[3-(N,N-dialkylamino)propyl]ether (reaction 4).
