| titleOfInvention | Method for preparing acetylsalicylic acid DL-lysine salt |
| abstract | In the present invention, acetylsalicylic acid is dissolved in 94% to 96%, in particular 95% ethanol, treated with activated carbon, aseptically treated, then sterilized and then slowly added aseptic powdery DL-lysine or its monohydrate while stirring under cooling. Thereby crystallizing the acetylsalicylic acid DL-lysine salt, and the crystallized DL-lysine salt is filtered under vacuum, washed with a solvent, and dried under vacuum. According to the method of the present invention, since no external water is added during the reaction, it is possible to recover the entire amount of the high-purity ethanol used after the reaction is completed without changing the purity, and it is economical, and crystallization of DL-lysine salt of acetylsalicylic acid is greatly precipitated. This provides the advantage of easy recovery of the crystals. |
