Production method | Made by the reaction of monochloroacetic acid and sodium hydroxide. Dissolve monochloroacetic acid in distilled water, carefully add liquid alkali to adjust the pH to 9, with the addition temperature of alkali rising, and finally to boiling, continue to maintain at 80-100 ℃ for 2 hours, during which the pH value is not lower than 9. Then concentrate until the film appears on the liquid surface, add an appropriate amount of distilled water to filter while hot, cool the filtrate to about 15 ℃, filter and crystallize, and then refine to obtain the finished product. |
