Description
DescriptionPhthalic anhydride is an organic compound with the formula C₆H₄(CO)₂O. It is the anhydride of phthalic acid and is a principal commercial form of phthalic acid. This white solid is an important industrial chemical, especially for the large-scale production of Plasticizers for plastics . This compound was the first anhydride of a dicarboxylic acid to be used commercially.ApplicationOne of the important Organic Chemical Raw Materials. It can be used as an intermediate of organic compounds such as plasticizer, alkyd resin, unsaturated polyester resin, dye and pigment, medicine, food additive and pesticide.SpecificationsItemSpecificationsResultsAppearanceWhite flake solidor powderWhite flake solid with white powderContent%≧99.999.96Melt chromaticity No.≤2010Thermal stability chroma No.≤5030Free mass fraction%≤0.20.018Benzoic acid≤0.050.01Packing specifications25KG paper plastic bag24MT/20GP (palletizing)25MT/20GP (without support)CertificationsISO 9001.
