Chemical properties of fumaric acid:
The simplest unsaturated dicarboxylic acid. It was first discovered in Yanhusuo and also found in various mushrooms and fresh beef. Trans butyric acid and maleic acid are geometric isomers of each other, and trans butyric acid is transformed into maleic acid when heated to 250-300 ℃. Trans butenedioic acid can also generate monobasic and binary esters or amides, but cannot generate monobasic acyl chloride. It reacts with phosphorus pentachloride or thionyl chloride to form binary acyl chloride. Trans butyric acid is oxidized by potassium permanganate to form racemic tartaric acid.
