摘要
N,N-Diisopropylethanoamine was synthesized from diisopropylamine and ethylene oxide,and then chloridized to N,N-diisopropyl-2-aminoethyl chloride,which finally went through amindysis in benzene to(produce) the title product N,N-diisopropyl ethanediamine.In these reactions,the optimum molar ratios were 1.2∶[KG-*3/5]1 for ethylene oxide to diisopropylamine,2∶[KG-*3/5]1 for thionyl chloride to N,N-diisoproylethanoamine,and(12∶[KG-*3/5]1) for ammonia to N,N-diisopropyl-2-aminoethyl chloride,respectively.The suitable reaction time,temperature,and solvent were also discussed.The total yield of 81.4% was obtained for the title product.
N,N-Diisopropylethanoamine was synthesized from diisopropylarnine and ethylene oxide, and then chloridized to N, N-diisopropyl-2-aminoethyl chloride, which finally went through amindysis in benzene to produce the title product N,N-diisopropyl ethanediamine. In these reactions, the optimum molar ratios were 1.2：1 for ethylene oxide to diisopropylamine, 2 ： 1 for thionyl chloride to N, N-diisoproylethanoamine, and 12：1 for ammonia to N,N-diisopropyl-2-aminoethyl chloride, respectively. The suitable reaction time, temper- ature, and solvent were also discussed. The total yield of 81.4% was obtained for the title product.
