PROCEDE AMELIORE DE SYNTHESE DE BIS[3-(N,N-DIALKYLAMINO)PROPYL)ETHERS |
摘要 |
<p>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).</p> |
