PHTHALIC ANHYDRIDE

Product Description

Phthalic anhydride is a white,crystalline solid with a characteristic pungent odor. It is produced throughthe oxidation of o-xylene or naphthalene in the presence of a catalyst,followed by purification processes. Phthalic anhydride serves as a key rawmaterial in the manufacture of various chemicals, plastics, and resins. It isprimarily used in the production of phthalate esters, which are widely used asplasticizers in the production of polyvinyl chloride (PVC) and other polymersto impart flexibility and durability. Additionally, phthalic anhydride is usedin the production of alkyd resins, which find applications in coatings, paints,and adhesives. It also serves as a precursor in the synthesis of phthalic acidand its derivatives, which are used in the production of polyester resins,dyes, and pharmaceuticals. Phthalic anhydride's versatility and reactivity makeit a valuable compound in various industrial processes, contributing to theproduction of a wide range of consumer and industrial products. However,exposure to phthalic anhydride should be controlled, as it can cause irritationto the skin, eyes, and respiratory system. Proper handling procedures andsafety precautions should be followed during its transportation, storage, anduse.
