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 1.2:1 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,temperature,and solvent were also discussed.The total yield of 81.4% was obtained for the title product.
