Process for the preparation of beta-hydroxypropionic acid amide |
| abstract |
1. A process for the production of beta-hydroxy-propionic acid amide by the conversion of acrylonitrile with water in the presence of basic catalysts, characterized in that the conversions carried out in the presence of metals and/or metallic compounds as heterogenous catalysts at pH values from 11.8 to 13.5, and at temperatures between 20 degrees C and 200 degrees C. |
