Description:
Chemical name: Trans-butenedioicacid
Molecular formula: C4H4O4
Molecular weight: 116.07
CAS NO.: 110-17-8
Properties:
White odorless powder or crystalline solid particles, with speical sourness that is as strong as 1.5 times of citric acid. It is soluble in ethanol (5.76g/100g,30), slightly soluble in water (0.63g/100ml,25) and in ether, and very slightly soluble in chloroform. It has no hygroscopicity, and will sublime at 200. Boiling point: 290 (decompose). It will turn to maleic anhydride at 230, and will generate DL-malic acid if boiled with water.
Package:
25kg net in plastic woven bag lined with PE bag. 18 MT/20'FCL (with pallet) or 20MT/20'FCL (without pallet). 500kg-1000kg container bags of all specifications are available.
