METHOD OF PRODUCING METHIONINE |
| 摘要 |
The invention provides the following method capable of producing methionine in a shorter time by making rapid progress of the hydrolysis of 5-(2-methylmercaptoethyl)hydantoin from an aqueous 5-(2-methylmercaptoethyl)hydantoin solution containing ammonia component. A method of producing methionine is the method comprising hydrolyzing 5-(2-methylmercaptoethyl)hydantoin in an aqueous 5-(2-methylmercaptoethyl)hydantoin solution containing ammonia component, wherein the hydrolysis is performed after the ammonia component is removed from the aqueous solution. |
