Product Description Product DescriptionPhthalic anhydride is an organic compound with molecular formula c8h4o3. It is a cyclic anhydrideformed by intramolecular dehydration of phthalic acid. Phthalic anhydride is a white solid. It is animportant raw material in chemical industry, especially in the manufacture of plasticizer. Hydrolysis,alcoholysis and ammonolysis can occur, and anthraquinone derivatives can be synthesized byreacting with aromatic hydrocarbons. Phthalic anhydride is industrially prepared by vapor phaseoxidation of naphthalene and air at 350 ~ 360 oC under the catalysis of vanadium pentoxide.It can also be prepared by air oxidation of o-xylene.ItemStandardProduct NameO-Phthalic Anhydride,Phthalic Anhydride,PAPurity≥99.5%CAS NO85-44-9EINECS No.201-607-5AppearanceWhite scale or crystalline powderMelting chromaticity number≤20Crystallization point oC≥130.8Thermal stability color number≤50Free acid%≤0.20Molecular FormulaC8H4O3ApplicationPlasticizer Manufacturing Raw Material.Curing agent for epoxy resin etc.Phthalic anhydride uses1.Phthalic anhydride is one of the most important organic chemical raw materials, and its mainderivatives are dibutyl phthalate; Dioctyl ester and diisobutyl ester are used as plasticizers forPVC, etc; It can also be used to produce unsaturated polyester resin; Alkyd resin; Dyes andpigments; Various paints; Food additives; Phenolphthalein, a laxative in medicine; Imiphos inpesticides; Clomazone and saccharin sodium, etc.2.Phthalic anhydride is used as curing agent of epoxy resin.
