Method for producing fumaric acid |
| abstract |
(57) [Abstract] [Purpose] [Structure] In the process for producing fumaric acid by isomerizing maleic acid, thioureas are used as a main solvent and a Lewis acid is used as a co-catalyst, in the presence of an alkaline compound, in an aqueous solvent. A method for producing fumaric acid, which comprises reacting with. According to the method of the present invention, fumaric acid can be produced industrially advantageously in a short time with a high yield. |
