METHOD FOR PRODUCING LAUROLACTAM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method for producing laurolactam solving a problem of a large amount of sulfonic acid loss or a large energy loss by producing the laurolactam with the Beckmann rearrangement of cyclododecanone oxime by using a catalytic amount of methane sulfonic acid. <P>SOLUTION: This method for producing the laurolactam by the Beckmann rearrangement of the cyclododecanone oxime is characterized by using the methane sulfonic acid in acetonitrile. <P>COPYRIGHT: (C)2009,JPO&INPIT |
