| Abstract: | The method for synthesizing betaine with sodium monochloroacetic acid and trimethylamine as raw materials was introduced.At first,they reacted for half an hour at room temperature,then at 50℃～55℃ for an hour and at 80℃～85℃ for an hour,last betaine was separated from aqueous solution by strong acid inoexchange resin.The yield was over 97% and the purity could reach 98.5%.This method had the advantages of simple procedure,short reaction time,mild reaction conditions,high product purity and etc. |
