| EPA chemical substance information | information provided by: iaspub.epa.gov (external link) |
| Use | intermediate of L-lysine. |
| production method | cyclohexene is used as a raw material, which is obtained by addition, ammonification and Beckmann rearrangement. (1) addition in the presence of liquid sulfur dioxide medium, cyclohexene is reacted with nitrosyl chloride to obtain bis-(2-chloro-1-nitroso-cyclohexane). (2) amination in the presence of a small amount of hexamethylenetetramine, bis-(2-chloro-1-nitroso-cyclohexane) is reacted with liquid chlorine to obtain α-aminocyclohexanone oxime hydrochloride. (3) Beckmann rearrangement α-aminocyclohexanone oxime hydrochloride is reacted by a Beckmann rearrangement in the presence of a translocator chlorosulfonic acid and sulfuric acid to give DL-aminocaprolactam. |
