It is soluble in ethanol (5.76g/100g,30°c), slightly soluble in water (0.63g/100ml,25°c) and in ether, and very slightly soluble in chloroform. It has no hygroscopicity, and will sublime at 200°c. Boiling point: 290°c (decompose). It will turn to maleic anhydride at 230°c, and will generate DL-malic acid if boiled with water.       Main Application and Functions:   1) Fumaric acid can be used as an acidulant.2) Fumaric acid has bacteriostatic and antiseptic function. 3) Fumaric acid can be used as acidity […]
