Method for preparing solid acid catalyst and method for producing lactam compound using the catalyst |
| abstract |
The present invention provides a method for producing a corresponding lactam compound by a Beckmann rearrangement reaction from a cycloalkanone oxime compound. SOLUTION: At least one compound selected from the group consisting of oxides and hydroxides is present in the lower layer part of the pipe, and a catalyst having the ability to oxidize sulfur dioxide with oxygen is present in the upper layer part, and contains sulfur trioxide. A solid acid catalyst is prepared by contacting with a gas. A method for producing a corresponding lactam compound from a cycloalkanone oxime compound by a Beckmann rearrangement reaction in the presence of a solid acid catalyst obtained by this preparation method. [Selection figure] None |
