脂肪族酰胺二元醇的合成与表征

Synthesis and Characterization of Aliphatic Amidediols

以ＤＬ－乳酸、ε－己内酯及乙二胺和己二胺为原料合成了四种结构的脂肪族酰胺二元醇，并用ＩＲ，１ＨＮＭＲ，ＤＳＣ对酰胺二元醇的结构进行了表征。

Four kinds of aliphatic amidediols were synthesized from DL lactic acid or ε caprolactone and aliphatic diamine. DL lactic acid based amidediols were prepared by reacting DL lactic acid with aliphatic diamine at 120℃￣140℃ for 4h and then 190℃￣200℃ for another 4h. ε Caprolactone based amidediols were obtained from the mixtures of ε Caprolactone and diamine heating at 140℃ for 4h. Characterizations of the amidediols were investigated by DSC, 1H NMR and IR spectrum.
