    摘要: The invention concerns an improved method for synthesising bis[3-(N,N-dialkylamino)propyl]ethers from acrylonitrile, comprising the following reactions: • - a first addition reaction of a water molecule and an acrylonitrile molecule to produce 3-hydroxypropionitrile (reaction 1) • - a 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 bis(2-cyanoethyl)ether to produce a reduction of the nitrile functions into primary amine functions to produce bis(3-aminopropyl)ether (reaction 3); • - aminoalkylation reaction of bis(3-aminopropyl)ether to produce bis[3-(N,N-dialkylamino)propyl]ether (reaction 4).
