摘要：

Konjac glucomannan(KGM)was aminated by 2-chloroethyl-amine(CEA)as reagent so as to study the influence of concentration of CEA(based on the amount of KGM),concentration of NaOH,reaction time and temperature on the extent of amination.And the molecular simulation technology was adopted to analyze the conformation stability of aminate(AKGM).The results indicate that when the amount of CEA is higher,the extent of amination is higher.The optimum concentration of NaOH,reaction time and temperature are 10%NaOH,70℃and 45 min,respectively.IR shows KGM is successfully aminated.The conformation of AKGM is in a random clew-like shape.
