2-Aminoacetic acid methyl ester - References
| use | methyl glycine Chinese alias 2-methyl aminoacetate. Glycine methyl ester salt is mainly used as household insecticides, pyrethrins and raw materials for the pharmaceutical industry, such as the preparation of chrysanthemum acid and dichlorochrysanthemum acid, and the intermediate of the fungicide iprodione. |
| Preparation | A synthesis method of L-glycine methyl ester salt product, which comprises the following steps: 1) Add a certain weight of L-glycine into methanol and stir evenly, and slowly add concentrated sulfuric acid under normal temperature conditions; 2) After the concentrated sulfuric acid is added, the obtained solution is heated, refluxed and cooled; 3) The obtained L-glycine methyl sulfate methanol solution is concentrated to be evaporated without methanol to obtain L-glycine methyl sulfate concentrated solution; 4) The concentrated solution is cooled to 20-23 ℃, purified water is added to prepare L-glycine methyl sulfate aqueous solution, and the pH of the aqueous solution is adjusted to 0-5 with ammonia water, it was stored at 0~15 ℃. |
