A process for preparing sodium acetylsalicylate (sodium aspirin) in the form of plate-like crystals by preparing a solution of sodium aspirin, transferring the solution to a crystallizer, agitating the solution while cooling the crystallizer, intermittently adding seed crystals as crystallization progresses, separating the crystals from the mother liquor, and drying in a fluid bed dryer. |
