The invention belongs to the technical field of separation and purification of compounds, and discloses a method for separating 2-adamantanone, comprising step A: a process of preparing a mixed solution, step B: a process of dissolving, step C: a process of flocculation, and step D: a process of removing impurities , step E: organic phase extraction process, step F: distillation process, step G: concentrated sulfuric acid recovery process; the present invention uses solvent and flocculant, and is processed at a certain temperature to achieve high boilers, 2-adamantanone and dilute The sulfuric acid is separated at one time, and the purity of the 2-adamantanone product obtained by the separation and purification of the present invention is greater than or equal to 99%, which can effectively improve the product quality. Green and environmental protection, reduce pollution caused by sulfate waste residue, can reduce production costs. |
