Chemical properties
The easiest unsaturated dicarboxylic acid. First determined in fusso, it is additionally located in many types of mushrooms and sparkling beef. Antibutenedioic acid and maleic acid are geometric isomers of every other, and transbutenedioic acid is heated to 250-300 °C to convert to maleic acid. TBHT additionally produces mono- and di-based esters or amides, however now not monohydryl chlorides. It reacts with phosphorus pentachloride or thionyl chloride to shape diacid chloride. Reverse butenedioic acid is oxidized by using potassium permanganate to produce racemic tartaric acid.
