FAQs of Phthalic Anhydride/Phthalic Acid Anhydride

What is phthalic anhydride made from?

Phthalic Anhydride is made from phthalates or naphthalene. The most common method involves the catalytic oxidation of o-xylene with air over a vanadium pentoxide catalyst at high temperatures. This process yields phthalic anhydride as a major product. Another method involves the catalytic oxidation of naphthalene with air over a metal oxide catalyst. Both processes are industrially significant for the production of phthalic anhydride, which is a key intermediate chemical in the production of various plastics, resins, and other industrial products. Douwin, as one of the most professional phthalic anhydridemanufacturers and suppliers in China, produces and supplies high-quality Phthalic Anhydride.

What is phthalic anhydride used for?

It is widely used in the production of plasticizers and pigments. It can also be used as a scorch retarder, light stabilizer, and heat stabilizer. Mainly used in the production of plasticizer, unsaturated polyester resin, alkyd resin, saturated polyester polyol, also used in the production of anthraquinone and its derivatives (dyes), isocyanic anhydride and phthalocyanine dyes (paints, ink pigments), halogenated acid anhydride (reactive flame retardants and flame retardants intermediates), polyether imide resin, medicine, pesticides, saccharin, and other products. In the polyurethane industry, it is mainly used for the synthesis of aromatic polyester polyols, which can be used for rigid polyurethane foam, and can also be used for polyurethane adhesives, coatings, etc. In addition, phthalate plasticizers are also used in small amounts in polyurethane products. As an experienced phthalic anhydride manufacturer, Douwin provides high-quality phthalic anhydride products to our customers for their unique application requirements. If you are looking for reliable phthalic anhydride manufacturers, don't hesitate to contact us directly to get the latest phthalic anhydride price.

Is phthalic anhydride dangerous?

If exposed to phthalic anhydride, it may cause acute irritation to personnel, including irritation to eyes, respiratory tract and skin, but no permanent damage has been observed.

Which process reaction does formation of phthalic anhydride take place by?

There are three ways of the phthalic anhydride production process: Ortho-xylene process, naphthaline process and mixing process.
