Method for producing maleimide |
| abstract |
(57) [Summary] [Object] An object of the present invention is to industrially produce a corresponding maleimide from a maleamic acid ester compound such as butyl maleamic acid or cyclohexyl maleamic acid with high yield and high selectivity. It is to provide a method of manufacturing advantageously. A maleic acid ester compound is heated in the presence of superheated steam together with at least one catalyst selected from the group consisting of a sulfonic acid catalyst and a phosphoric acid catalyst to carry out a dealcohol ring closure reaction. . |
