Method for producing 2-hydroxy-4-methylthiobutanoic acid |
| abstract |
(57) [Problem] To provide a method for producing 2-hydroxy-4-methylthiobutanoic acid which can efficiently extract 2-hydroxy-4-methylthiobutanoic acid with good operability. SOLUTION: (A): a step of hydrating 2-hydroxy-4-methylthiobutanenitrile in the presence of sulfuric acid to obtain a reaction solution containing 2-hydroxy-4-methylthiobutanamide, (B): (A) A) a step of subjecting 2-hydroxy-4-methylthiobutanamide contained in the reaction solution obtained in the above to a hydrolysis reaction to obtain a reaction solution containing 2-hydroxy-4-methylthiobutanoic acid, and (C): (B) And b) separating the reaction solution obtained in the step (b) into an oil layer containing 2-hydroxy-4-methylthiobutanoic acid and an aqueous layer. A method for producing 2-hydroxy-4-methylthiobutanoic acid circulating in (C). |
