Reaction Conditions:
with maleic anhydride in lithium hydroxide monohydrate at 190; for 6 h;Inert atmosphere;Autoclave;Green chemistry;Reagent/catalyst;
Steps:
4
Saturated malic acid in the mother liquid and the water suction filtrate lossy process, the need to fill the filtrate in Example 3 plus a certain amount of the mass of 306g at a concentration of 50%, together with 300g of maleic anhydride was added to a 1000ml autoclave in with N2 Air autoclave was replaced three times at 190 degree, speed of 300 rev / min under conditions of reaction 6h, after the reaction to adjust speed of 100 rev / min to cool to room temperature. Remove the liquid crystalline fumaric acid, fumaric acid filtration to give crystals, placed in 80 oven bake 4h. Finally get fumaric 353.3g, a yield of 99.5%.
