- 摘要：在强碱性条件下由烯丙基氯和二甲胺反应,先生成二甲基一烯丙基叔胺,分离后再次加入烯丙基氯,于丙酮介质中结晶析出二甲基二烯丙基氯化铵,产率达75%,以复合引发剂引发聚合,得分子量994万的高聚物.絮凝实验证明,最佳投药量一般小于1ppm,如果与铝盐配合使用,可使浊水达更高的澄清度.
- Abstract：By the reaction of allyl chloride with dimethylammonium in the solution of strong alkali,dimethylallylammonium(tertiary amine) formed. The tertiary amine was separated and added along with allyl chloride to acetone, then the dimethyldiallylammonium cheoride crystallized out. The rate of output was 75%. The monomers were then polymerized in the presence of a composite initiator, the molecular weight of the obtained polymer is 99.4×104. The optimum dosage in jar test was below 1ppm. If the polymer is used along with Al2(SO4)3 as a flocculant for water treatment, higher efficiency of flocculation will be achieved.
