Method for producing 2-hydroxyisobutyric acid and methacrylic acid from acetone cyanohydrin |
| abstract |
The present invention provides a process for producing 2-hydroxybutyric acid, wherein the acetone cyanohydrin is converted to 2-hydroxybutyric acid using an enzyme catalyst having nitriase activity or a combination of nitrile hydratase and amidase activity. It is about. The present invention also includes a method for producing methacrylic acid, which dehydrates 2-hydroxyisobutyric acid prepared using the catalyst to produce methacrylic acid. |
