| titleOfInvention | Fumaric acid production catalyst and method for producing fumaric acid using the catalyst |
| abstract | (57) [Summary] [Object] To provide a catalyst for producing fumaric acid by an isomerization reaction of maleic acid and a method for efficiently producing high-quality fumaric acid using the catalyst. [Structure] This catalyst for producing fumaric acid contains, as an essential component, at least one thiourea compound selected from (A) bromate and (B) thiourea and its derivatives. Further, it may contain at least one water-soluble metal salt selected from water-soluble salts of cerium, copper, manganese and iron. Then, maleic acid is isomerized in the presence of this catalyst to produce fumaric acid. [Effect] Despite the small total amount of catalyst added, 1 The isomerization reaction of maleic acid at a relatively low temperature of 00 ° C. or lower can be carried out with a high reaction rate. In addition, the fumaric acid produced has an extremely low content of unreacted maleic acid and by-product malic acid, is free from coloration, and is excellent in heat stability. |
