| 摘 要： | 以甲醇为反应介质，常温下用碳酸钠中和氯乙酸，过滤，制得氯乙酸钠，然后在无水甲醇中与过量三甲胺反应，经过滤除盐，浓缩，冷却，干燥，制得甜菜碱。以氯乙酸计收率92．5％。改进后的工艺较好地解决了化学合成法中的除盐关键技术。

| Abstract: | Betaine was synthesized from sodium chloroactate,which from chloroactic acid by neutralising with sodium carbonate in methanol medium,and reacted with excess trimethylamine in absolute methanol,then via filtration,concentration,cooling and drying with an overall yield of 92.5%(base on chloroactic acid).The improved process approvingly solved the pivotal problem removing salt NaCl. |
