| 摘要 |
The method of producing a salt of 1-amino-1,3,3,5,5-pentamethylcyclohexane comprising steps (i) to (v): (i) converting isophorone to 3,3,5,5-tetramethylcyclohexanone; (ii) converting 3,3,5,5-tetramethylcyclohexanone obtained in step (i) to 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane; (iii) converting 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane obtained in step (ii) to 1-chloroacetamido-1,3,3,5,5-pentamethylcyclohexane; (iv) converting 1-chloroacetamido-1,3,3,5,5-pentamethylcyclohexane obtained in step (iii) to 1-amino-1,3,3,5,5-pentamethylcyclohexane; wherein at least one of 3,3,5,5-tetramethylcyclohexanone, 1-hydroxy-1,3,3,5,5-pentamethylcyclohexane, 1-chloroacetamido-1,3,3,5,5-pentamethylcyclohexane, is not subjected to a purification step. |
