Phthalic Anhydride (PA)

White scaly or Crystalline powder, Molecular formula C8H403, Molecular weight 148.12, Melting point 131.1l ℃, Boiling point 284.5 ℃, Flash point 151 ℃ (close), 165 ℃ (open), Spontaneous combustion point 584 ℃, Density (Solid) 1.527g / cm3, insoluble in water, soluble in water, alcohol, ether, benzene and most organic solvents. Phthalic anhydride is a cyclic anhydride, is an important chemical raw material, especially for plasticizer manufacturing. Dibutyl phthalate, Dioctyl phthalate are important plasticizers. Phthalic anhydride and polyols (such as glycerol, pentaerythritol) can generate polyarylate resin in condensation way, used in paint industry; if an unsaturated acid with ethylene glycol happening condensation, the resulting chemicals is unsaturated polyester resin, for the manufacturing of insulating paint and glass fiber reinforced plastics . Phthalic anhydride is a raw material of benzoic acid, terephthalic acid, also used in pharmaceutical synthesis. whatsapp:+8615617816797.
