Glycine, N-(carboxymethyl)-N-methyl- - Reference Information
| use | for organic synthesis. |
| production method | sodium chloroacetate solution and methylamine solution are reacted below 50 ℃, barium chloride dihydrate solution is added to the reaction mixture, and the isolated barium salt of methyliminodiacetic acid is filtered. The barium salt and sulfuric acid are then reacted to separate the barium sulfate precipitation. The filtrate is concentrated under reduced pressure, anhydrous methanol is added, cooled, filtered, washed with methanol, and dried at 100 ℃ to obtain methyliminodiacetic acid. Yield 63-71%. |
