摘　　要：对二甲基二烯丙基氯化铵（ＤＭＤＡＡＣ）的合成工艺进行了改进。控制合成反应温度在８０℃以下，采取减压蒸馏、减压过滤等提纯工艺步骤，得到无色到淡黄色的水溶液，产物的收率最高达９２．４％，一般可达８５％左右，含无机盐在１％左右。用溴酚蓝对ＤＭＤＡＡＣ进行定性分析，用四苯硼酸钠及折光率法进行定量分析的方法进行了探讨。The improvements in synthesis of dimethyldiallylammonium chloride (DMDAAC) are as follows: maintaining the reaction temperature below 80℃; purifying the crude product by distillation and filtration under vacuum. In result DMDAAC is obtained in colorless to yellowish aqueous solution with yield 92.4% maximally and 85% in average and contaiining 1% NaCl. An investigation is also made on determining DMDAAC qualitatively by bromophenol blue test and quantitatively by tetraphenyl boron sodium precipitation reaction and refractive index measurement.
