| titleOfInvention | Preparation method of fumaric acid |
| abstract | The application discloses a preparation method of fumaric acid, which takes malic acid as a raw material, and the malic acid is catalyzed to carry out dehydration reaction under the condition of no solvent or in a hydrocarbon medium to obtain the fumaric acid. The preparation method has simple and direct reaction process, and the key raw material malic acid can be obtained by biomass fermentation, which is a supplement to the existing production route to relieve the dependence on fossil resources. In addition, compared with the traditional production method of fumaric acid, the method avoids the use of high-pollution catalysts such as thiourea, bromine-containing oxides and the like, and the dehydration reaction can be carried out under the normal pressure condition, thus being green and safe. The used catalyst and the reaction process thereof are efficient and clean. |
