摘　　要：以甲基丙烯酸二甲氨基乙酯(DM)和环氧氯丙烷(ECH)为主要原料,合成了一种活性体O-甲基丙烯酰-氧乙基二甲基环氧丙基氯化铵(ODEAC)。采用单因素实验分别讨论了反应溶剂、反应温度、物料比及反应时间对产物的转化率和环氧值的影响,确定了最佳合成工艺为:反应温度60℃,反应溶剂为异丙醇,物料比n(ECH)∶n(DM)=1∶1.6,反应时间4 h,在该条件下目标产物的转化率可达91.67%。并采用傅里叶变换红外光谱仪(FTIR)和核磁共振波谱仪(1HNMR)对产物结构进行了表征。O-Methyl acryloyl-oxygen ethyl dimethyl epoxypropyl ammonium chloride （ODEAC）, an active intermediate ,was synthesized with 2-dimethylamino ethyl methacrylate（DM） and epichlorohydrin （ECH） as the main raw materials. The influence of the solvents,reaction temperature, material ratio and reaction time on product conversion and the epoxy value was respectively discussed based on a single factor experiment, and the optimum synthetic process conditions were ascertained as follows：the reaction temperature of 60 ℃, using isopropanol as the solvent, n （ECH） ： n （ DM ） = 1 ： 1.6, and the reaction time of 4 h;under such optimum conditions, the target product conversion is 91.67 %. And the structure of the product was characterized by means of FTIR and ^1HNMR.
