| 发明名称 | Process for producing adipic acid crystals | ||
| 摘要 | A method for producing crystals of adipic acid is described. In particular, a method for recovering adipic acid in the form of crystals with low impurity content, obtained by crystallization steps in particular using reaction media for synthesizing adipic acid is described. A purification method including a step of crushing the crystals for easier removal or the migration of the impurities in the crystals is also described. | ||

| 主权项 | 1. A process for producing adipic acid crystals from a solution of adipic acid, the process comprising at least one step of purification by crystallization and one step of separation and recovery of the adipic acid crystals, wherein the adipic acid crystals are subjected, before the separation and recovery step, to a grinding phase. | ||
