| 中文摘要 |
| 为制备聚二甲基二烯丙基氯化铵絮凝剂,采用二步法制备了二甲基二烯丙基氯化铵单体,即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,将该叔胺分离出来并再次加入烯丙基氯,于丙酮介质中结晶析出季胺盐晶体。该法制备的单体具有很高的纯度,产率可达72%. |
| 英文摘要 |
| Dimethyldiallylammonium chloride (DMDAAC)was prepared by two-step method.first,allyl chloride reacted with dimethylamine in the solution of strong alkaili,producing dimethyallyammonium (tertiary amine).Secondly,the tertiary amine was separated and added along with allyl chloride to acetone then the DMDAAC crystallized from the acetone solution. |
