PHTHALIC ANHYDRIDE

Product Description

Phthalic anhydride is an organiccompound widely used in the production of various chemicals, plastics, andresins. It is produced through the oxidation of o-xylene or naphthalene in thepresence of a catalyst, followed by purification processes. Phthalic anhydrideis a key raw material in the manufacture of phthalate esters, which are used asplasticizers in the production of polyvinyl chloride (PVC) and other polymersto impart flexibility and durability. Additionally, it serves as a precursor inthe synthesis of phthalic acid and its derivatives, which find applications inthe production of polyester resins, alkyd resins, and dyes. Phthalic anhydrideis also used in the production of pharmaceuticals, insecticides, and flameretardants. Its versatile nature and reactivity make it a valuable intermediatein numerous industrial processes, contributing to the production of a widerange of consumer and industrial products. However, exposure to phthalicanhydride should be controlled as it can cause irritation to the skin, eyes,and respiratory system. Proper handling procedures and safety precautionsshould be followed during its transportation, storage, and use.
