| 摘 要： | 以羟乙基纤维素为原料、2-氯-4，6-二（N，N-二甲基-N-苄基-1，3-丙二胺）-1，3，5-均三嗪（BT）为改性剂，合成新型季铵盐阳离子羟乙基纤维素醚，讨论了影响产物取代度的主要因素。结果表明：在异丙醇稀释剂中，NaOH和改性剂的物料量比为1．2：1，改性剂和羟乙基纤维素的物料量比为1．5：1，反应温度为95℃、反应时间为5h时，产物的取代度最高达0．24。

| Abstract: | Hydroxyethyl cellulose(HEC)and 2-chloro-4,6-di(N,N-dimethyl-N-benzyl-1,3- propanediamine) -1,3,5-triazine(BT)were respectively used as the material and the modifier to prepare quaternary ammonium hydroxyethyl cationic cellulose ether,and the effects factors in the preparation were analyzed.The results show that in isopropanol medium with a HEC/BT molar ratio of 1.5:1,cationic cellulose ether with a degree of substitution(DS)of 0.24 can be obtained at 95℃after treatment for 5 h. |
