| titleOfInvention | Process for the preparation of pure anhydrous sodium acetylsalicylate |
| abstract | Pure anhydrous stable sodium acetylsalicylate is prepared by first reacting acetylsalicylic acid with a basic sodium compound, giving a concentrated aqueous solution of sodium acetylsalicylate. From this solution, sodium acetylsalicylate dihydrate is then precipitated in the form of granular platelet crystals. The dihydrate is separated off and the water of hydration is removed. The sodium acetylsalicylate is used for the same purposes as aspirin. |
