Fumaric acid 25kg/bag Alternative name: fumaric acid 2800 Sinopec
The synonym fumaric acid generally refers to fumaric acid
Relative density: 1.635 (20/4 ℃) CA S # 110-17-8
Fumaric acid, also known as fumaric acid, corydric acid or lichen acid, namely fumaric acid (IUPAC is called (E) - butenedioic acid), is a colorless, flammable crystal, carboxylic acid derived from butene. Its chemical formula is C4H4O4. Combustion of fumaric acid will release maleic anhydride smoke.
Chinese name Fumaric acid Molecular formula C4H4O4 Molecular weight 116.07
Chinese name: fumaric acid
Chinese alias: fumaric acid; (E) 2-butenedioic acid; Trans-1,2-ethylenedihydroxylate; Fumaric acid; Cordieric acid; E) - 2-butene bis; Fumaric acid; Butene diacid, trans; Fumaric; 1,2-Ethylenedicarboxylic acid; Butenedioic acid (fumaric acid); Fumaric acid/fumaric acid; Allomaleic acid; Fumaric acid; Fumaric acid; E-butenedioic acid; Fumaric acid
Simple unsaturated dicarboxylic acid. Also called fumaric acid or fumaric acid. It is found in Yanhusuo, and also in a variety of mushrooms and fresh beef. The fumaric acid and maleic acid are geometric isomers of each other. The fumaric acid is heated to 250-300 ℃ and converted into maleic acid. The fumaric 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. The fumaric acid is oxidized by potassium permanganate to form racemic tartaric acid.
