| 摘要 |
A method for obtaining 2-hydroxy-4-methylthiobutyric acid (methionine-hydroxy analog, MHA) in primarily free form which is stable in storage by distilling a product solution containing MHA and by producing MHA product mixtures with improved storage stability from such a distillate. The distillate can be produced directly starting from MHA raw products from any MHA production process, which can optionally also contain solvent or water. The starting material may also be a commercial MHA product. |
