PROCESS FOR THE PREPARATION OF LYSINE |
摘要 |
Lysine is produced by a process comprising the steps of 1. Nitrating cyclohexanone to form 2-nitrocyclohexanone; 2. Nitrosating the 2-nitrocyclohexanone to form 2-nitro-6-oximinocyclohexanone; 3. Ring opening the 2-nitro-6-oximinocyclohexanone in alcoholic base to form an ester of 2-oximino-6-nitrocaproic acid; 4. Hydrogenating the 2-oximino-6-nitro caproic acid alkyl ester to form an alkyl ester of lysine; and 5. Saponifying the lysine alkyl ester to afford lysine or a salt thereof.
