| titleOfInvention | Production method of glycolic acid crystals |
| abstract | The invention relates to a method for producing glycolic acid crystals from a glycolic acid solution, which comprises the steps of cooling the glycolic acid solution, adding the glycolic acid crystals as seed crystals to promote glycolic acid crystallization at a temperature lower than the saturation temperature of raw materials, and finally carrying out solid-liquid separation and drying to obtain the high-purity glycolic acid crystals. The technical scheme adopted by the invention better solves the problem of low efficiency of the crystallization process in the prior art, and can be used for the production of glycolic acid crystals. |
