Alpha-hydroxycarboxylic acid and its preparation method |
| abstract |
The present invention relates to a process for the preparation of selective and economically possible methacrylic acid and methacrylic acid esters, starting from acetone cyanohydrin, wherein in the first step 2-hydroxy-2-methylpropionic acid is water and suitable polarity. Prepared and isolated by reaction of sulfuric acid with acetone cyanohydrin in the presence of a solvent, methacrylic acid is subsequently prepared by β-elimination of water starting from 2-hydroxy-2-methylpropionic acid. |
