| titleOfInvention | A kind of refining method of progesterone |
| abstract | The invention relates to a method for purifying progesterone, which can improve the quality of the product, and includes the following steps: adding crude progesterone into a reaction vessel, adding a reaction solvent to the reaction vessel and stirring evenly, adding a decontamination agent, and stirring to obtain a first reaction system; the first reaction system is concentrated under reduced pressure to obtain a concentration system with a reaction solvent content of less than 10%; adding a dissolving solvent and water to the concentration system, stirring to dissolve it, and slowly adding an acid solution to obtain a second reaction system system; the second reaction system is allowed to stand to obtain a liquid-liquid layered system composed of an organic phase and an aqueous phase, and the organic phase is extracted from the liquid-liquid layered system; the organic phase is concentrated under reduced pressure and concentrated into the organic phase The content of the dissolving solvent is less than 40%, then add the crystallization solvent to obtain a crystallization system; let the crystallization system stand, crystallize, and obtain a solid-liquid mixed system; perform solid-liquid separation on the solid-liquid mixed system to obtain a solid, and the solid-liquid mixed system is obtained by solid-liquid separation It is dried to obtain a progesterone fine product. |
