The invention relates to an improved 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).
该发明涉及一种改进的方法,用于从丙烯腈合成双[3-(N,N-二烷基氨基)丙基]醚,包括以下反应:第一步是水分子和丙烯腈分子的加成反应,产生3-羟基丙腈(反应1);第二步是通过反应1得到的3-羟基丙腈分子和丙烯腈分子的加成反应,产生双(2-氰乙基)醚(反应2);将双(2-氰乙基)醚氢化,将腈官能团还原为一次胺官能团,从而产生双(3-氨基丙基)醚(反应3);将双(3-氨基丙基)醚进行氨基烷基化反应,产生双[3-(N,N-二烷基氨基)丙基]醚(反应4)。
