摘　　要：以2,3-环氧丙基三甲基氯化铵(EPTMAC)为醚化剂,在有机溶剂中合成了壳聚糖(chitosan)季铵盐,并选择出了最佳的合成路线。最佳反应条件为2,3-环氧丙基三甲基氯化铵水溶液质量分数为35%,n(EPTMAC)/n(chi-tosan)为1.5,反应温度为80℃,反应时间为10 h。在此条件下合成的产品转化率高,水溶性好,对油田污水具有良好的絮凝净水性能。The most preferable synthesis process for quaternary ammonium salt of chitosan in heterogeneous system was discussed. 2,3-epoxypropyl-trimethyl ammonium chloride （EPTMAC） was used as ethering agent, the molar ratio of EFTMAC to ehitosan was 1.5, and the mass fraction of EPTMAC was 35 %. The reaction temperature was 80 ℃, and the reaction time was 10 hours, The obtained quaternary ammonium salt of chitosan is soluble in water. It has fine flocculation performance to the oilfield produced water.
