摘要
本文采用乙醇胺与硫酸作用生成硫酸－β－氨基氢乙酯，再经环化制得吖丙啶．讨论了环化条件（蒸馏时间、碱的质量分数及甲醇洗涤）对叮丙牌产率的影响，以叮丙院法合成Ｎ，Ｎ－二烷基乙二胺，产率高达８５％～９０％．采用该中间体合成了二碳隔离型阳离子染料代替三碳隔离型阳离子染料，提高了染料鲜艳度．
he reactive cationic dyestuff intermediate N,N-dialkylethylene diamines have been prepared in good yield by the method of aziridine. The conditions of preparation are studied. The bright colour of the dyestuffs made from this intermediate is increased as compared with that of the similar ones which had been synthesized before by 3-dimethylaminopropylamine.
