| titleOfInvention | An improved synthetic method for glycine. |
| abstract | (57) [Summary] (Modified) [Purpose] Glycine, which can provide crude glycine of high purity with a high yield of 90% or more as compared with conventional glycine synthesis methods, and energy saving and economical To provide an improved synthetic method. [Structure] A step of chlorinating acetic acid using neutral red phosphorus as a catalyst to produce monochloroacetic acid (A) A step of distilling off unreacted acetic acid in a reaction product to obtain a molten crude monochloroacetic acid (B), And crude or purified monochloroacetic acid in a molten state are fed into a synthesis reaction tank, a lower alkanol is added as a solvent and then a tertiary alkylamine is added to react, and then paraformaldehyde is added at a temperature of 35 to 40 ° C. After adding and dissolving, a step of introducing ammonia gas into the reaction system at a temperature of 40 to 45 ° C. to cause reaction, and further raising the temperature after completion to complete the reaction to obtain crystalline glycine as a crystallized product (C) An improved synthetic method of glycine comprising: |
