About 25kg/500kg/600kg Bag CAS No 85-44-9 Purity 99.5% PA Phthalic Anhydride

Phthalic anhydride is the organic compound with the formula C6H4(CO)2O. It is the anhydride of phthalic acid. This colourless solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics. Phthalic anhydride is an important chemical intermediate in the plastics industry from which are derived numerous phthalate esters that function as plasticizers in synthetic resins. Phthalic anhydride itself is used as a monomer for synthetic resins such as glyptal, the alkyd resins, and the polyester resins. Phthalic anhydride is also used as a precursor of anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, and xanthene dyes. Phthalic anhydride is used in the synthesis of primary amines, the agricultural fungicide phaltan, and thalidomide. Other reactions with phthalic anhydride yield phenolphthalein, benzoic acid, phthalylsulfathiazole (an intestinal antimicrobial agent), and orthophthalic acid.

Versatile Industrial Applications

Phthalic Anhydride is a crucial ingredient in producing plasticizers, alkyd resins, dyes, pigments, pharmaceuticals, perfumes, and agrochemicals. Its high purity and consistent quality make it suitable for a diverse range of industrial chemical synthesis processes. This versatility supports various manufacturing sectors seeking reliable raw materials.

Quality, Safety, and Packaging

Offered in 25kg, 500kg, or 600kg bags, Phthalic Anhydride is packaged to ensure product integrity during transport and storage. It should be handled with care to avoid dust generation and must be stored in well-sealed containers in cool, dry environments. Adhering to GB/T 15336-2006 standards, it delivers consistent performance and meets stringent global export requirements.
