| titleOfInvention | Crystallization method of trisodium carboxylate and prepared trisodium carboxylate crystals |
| abstract | The invention discloses a crystallization method of trisodium caroxoate and a prepared trisodium caroxoate crystal. The crystallization method of trisodium carboxylate includes the following steps: (1) after dissolving the oily trisodium carboxylate raw material in methanol, then adding water; or dissolving the oily trisodium carboxylate raw material in water , and then add methanol to obtain an aqueous solution of trisodium carboxylate; (2) after fully mixing the trisodium carboxylate aqueous solution with a poor solvent, crystals are precipitated; (3) post-processing to obtain trisodium carboxylate crystals. The invention adopts the three-phase crystallization method of alcohol, water and poor solvent, which solves the problem of difficult crystallization of trisodium carboxylate, requires low equipment, does not require high energy consumption, can be used for scale-up production, and the obtained product has good properties and high purity. , the crystallization yield is high. |
