| titleOfInvention | Synthesis process of alpha-ketoglutaric acid sodium salt |
| abstract | The invention discloses a continuous flow synthesis process of alpha-ketoglutaric acid sodium salt, which comprises the following steps: (1) using H as NaOH 2 Dissolving O to prepare a NaOH solution with the mass fraction of 5-30% as a material A; (2) preparing alpha-ketoglutaric acid into an alpha-ketoglutaric acid solution with the mass fraction of 10-30% by using a solvent, and taking the alpha-ketoglutaric acid solution as a material B; (3) respectively injecting a material A and a material B into a mixer through a feeding pump, then entering a continuous flow microreactor, reacting and staying in the continuous flow microreactor for a preset time at a preset reaction temperature, and then collecting reaction liquid; wherein, in the reaction process, the molar ratio of NaOH to alpha-ketoglutaric acid is 1.0-2.2: 1; said material A and said material B being in said continuous flow microreactorThe reaction residence time of (a) is 1-10 min; (4) and carrying out post-treatment on the collected reaction liquid to obtain a solid product. The method has the advantages of simple and convenient operation, high yield, easy amplification, stable product quality and high purity. |
