| titleOfInvention | Method for preparing 2-hydroxy-4-(methylthio)butyric acid |
| abstract | The present invention relates to a process for the preparation of 2-hydroxy-4-(methylthio)butyric acid (HMTBA) from 2-hydroxy-4-methylthio-butyronitrile (HMTBN), the process comprising the steps of: hydrolyzing HMTBN to HMTBA in the presence of a mineral acid in a medium, neutralizing the medium by addition of a base, and a first phase comprising at least HMTBA and a salt, and a second phase containing a salt; isolating, wherein the method is performed by chromatography of the first phase, wherein the separation of HMTBA from the salt in the first phase. |
